Chapter 1: Foundations of Ethical Theory

1.1 What Is Ethics?

Ethics is the branch of philosophy that investigates questions about right and wrong, good and bad, virtue and vice, justice and injustice. It asks not merely what people do but what people ought to do and what kind of persons they ought to become. Unlike descriptive disciplines that report on moral behaviour as it exists—sociology, anthropology, psychology—ethics is fundamentally normative: it sets out standards, principles, and frameworks by which conduct and character can be evaluated.

Matthews (2019) distinguishes three broad domains within the study of ethics. Metaethics concerns the nature and status of moral claims themselves: Are moral truths objective or culturally constructed? Do moral facts exist independently of human opinion? Normative ethics develops systematic theories about which actions are right and which character traits are virtuous. Applied ethics brings those theories to bear on concrete practical problems—bioethics, environmental ethics, business ethics, and, as in this course, sexual and relational ethics. SRF 310 operates primarily in the domain of applied ethics but draws constantly on normative theories and occasionally touches metaethical questions about the objectivity or relativity of sexual norms.

1.1.1 Ethics vs. Morality

In everyday language “ethics” and “morality” are often used interchangeably, but a useful distinction can be drawn. Morality refers to the set of values, norms, and customs that a community or individual actually holds. Ethics is the reflective, critical study of those values and norms. A person’s morality tells them that adultery is wrong; ethics asks why it is wrong, whether it is always wrong, and what underlying principles ground that judgment. Throughout this course, we engage in ethical inquiry about sexual and relational practices that many people hold strong moral convictions about, and part of the educational aim is to distinguish between merely having moral feelings and reasoning carefully about them.

1.1.2 The Role of Ethical Theories

An ethical theory is a systematic framework that aims to provide general principles for determining the rightness or wrongness of actions, the goodness or badness of outcomes, or the virtuousness or viciousness of character. Theories serve several functions: they impose order on our moral intuitions, they help us reason about novel cases, they reveal hidden assumptions, and they enable productive moral disagreement by making premises explicit. No single theory commands universal assent, which is precisely why studying multiple theories is essential. In the context of sexuality and relationships, different theories will illuminate different dimensions of the same ethical problem—consent, harm, power, care, flourishing, justice—and competent ethical reflection requires facility with more than one lens.

1.2 Consequentialism

Consequentialism holds that the moral value of an action is entirely determined by its consequences. The right action is the one that produces the best overall outcome. The most influential form of consequentialism is utilitarianism, associated with Jeremy Bentham and John Stuart Mill, which defines the best outcome as the greatest aggregate well-being (or happiness, or preference satisfaction) for all affected parties.

1.2.1 Classical Utilitarianism

Bentham proposed a “felicific calculus” for summing pleasures and pains across all individuals affected by an action. Mill refined this by introducing qualitative distinctions among pleasures: intellectual and moral pleasures rank higher than merely bodily pleasures. For both, the fundamental principle is the greatest happiness principle: an action is right insofar as it tends to promote happiness and wrong insofar as it tends to produce unhappiness, where happiness is understood as pleasure and the absence of pain.

1.2.2 Consequentialism Applied to Sexual Ethics

Applied to sexual and relational contexts, consequentialism asks: What are the effects of a given sexual practice or relational arrangement on the well-being of all involved? Consensual sexual activity between adults that produces mutual pleasure and emotional satisfaction would be judged positively. Deception, coercion, or exploitation in sexual contexts would be judged negatively because of the suffering they produce. Importantly, consequentialism is neutral about the form of sexual expression or relationship structure; what matters is not whether the activity is heterosexual or homosexual, monogamous or polyamorous, but whether it produces good consequences for those involved and for society.

This neutrality is both a strength and a limitation. It provides a non-judgmental framework for evaluating diverse sexual practices, but it can struggle with cases where an apparently pleasurable outcome was obtained through morally questionable means—for instance, a deceptive seduction that the deceived party never discovers, thereby producing no measurable suffering. Critics argue that consequentialism cannot adequately account for the moral importance of honesty, fidelity, and respect independently of outcomes.

1.3 Deontological Ethics

Deontological ethics (from the Greek deon, meaning duty) holds that certain actions are intrinsically right or wrong, regardless of their consequences. The pre-eminent deontological theorist is Immanuel Kant, whose moral philosophy centres on the categorical imperative.

1.3.1 Kant’s Categorical Imperative

Kant formulated the categorical imperative in several ways, two of which are most frequently invoked:

1. The universalizability formulation: Act only according to that maxim by which you can at the same time will that it should become a universal law. An action is morally permissible only if you could consistently will that everyone in similar circumstances would act the same way.

2. The humanity formulation: Act so that you treat humanity, whether in your own person or in that of any other, always as an end and never merely as a means. This forbids using people solely as instruments for your own purposes.

1.3.2 Deontology Applied to Sexual Ethics

The humanity formulation has profound implications for sexual ethics. It grounds the moral centrality of consent: to engage in sexual activity with someone without their informed, freely given consent is to treat them merely as a means to one’s own gratification—a paradigmatic violation of the categorical imperative. Deontological ethics thus provides a principled foundation for condemning sexual assault, coercion, and deception.

Kant himself was notably conservative about sex, arguing that sexual desire inherently reduces the other person to an object of appetite, and that only within marriage could this objectification be morally redeemed through the mutual, contractual gift of one’s whole person. Contemporary Kantians have largely abandoned this restrictive view while retaining the core insight that sexual interactions must respect the autonomous agency and dignity of all participants. The emphasis on respect for persons, rather than mere calculation of pleasure and pain, gives deontological ethics a distinctive strength in analysing power dynamics, exploitation, and the ethics of truthfulness in intimate relationships.

1.4 Virtue Ethics

Virtue ethics shifts the focus from actions and their consequences to the character of the moral agent. Rooted in Aristotle’s Nicomachean Ethics, virtue ethics asks not “What should I do?” but “What kind of person should I be?” A virtuous person is one who has cultivated stable dispositions—virtues—such as courage, temperance, justice, honesty, compassion, and practical wisdom (phronesis). The right action is the action that a virtuous person would perform in the circumstances.

1.4.1 Virtue Ethics Applied to Sexual and Relational Life

Virtue ethics is particularly well suited to relational and sexual contexts because relationships are not one-off decisions but ongoing practices of character. A person who cultivates honesty will be truthful with their partner not because a rule commands it or because honesty maximises utility, but because truthfulness is constitutive of the kind of person they aspire to be. Similarly, virtues like temperance, generosity, loyalty, and empathy bear directly on how one conducts oneself in intimate relationships.

Aristotle’s concept of eudaimonia—variously translated as happiness, flourishing, or well-being—suggests that virtuous relationships are those that contribute to the flourishing of all parties. This framework can accommodate diverse relationship forms: the question is not whether a relationship is conventional but whether it is characterized by mutual respect, honest communication, care, and the pursuit of shared goods. A polyamorous relationship sustained by honesty, compassion, and equitable attention to all partners’ needs can be virtuous; a monogamous marriage corroded by deceit, contempt, and indifference cannot.

1.5 Care Ethics

Care ethics emerged in the 1980s from the work of Carol Gilligan and Nel Noddings as a challenge to the dominant emphasis on abstract principles, impartiality, and rights in moral philosophy. Rather than asking what abstract rules require, care ethics asks what attention to particular relationships and responsibilities demands.

1.5.1 Core Features of Care Ethics

Care ethics foregrounds several distinctive commitments:

• Relationality: Persons are not isolated, self-sufficient individuals but fundamentally relational beings whose identities, capacities, and well-being are constituted through their connections with others.
• Particularity: Moral reasoning must attend to the concrete details of specific situations and relationships rather than applying universal principles mechanically.
• Responsiveness: Ethical action requires attentive listening, empathy, and responsiveness to the expressed and unexpressed needs of those with whom one is in relationship.
• Vulnerability and dependency: All human beings pass through periods of vulnerability and dependency, and ethical life must be organized around the recognition of and response to this reality.

Held (2006) argues that care is both a practice and a value: it involves the actual work of maintaining and repairing relationships, and it recognizes that this work has moral significance that mainstream ethical theories have undervalued—in part because care work has historically been assigned to women and rendered invisible.

1.5.2 Care Ethics in Sexual and Relational Contexts

Care ethics provides a rich vocabulary for analysing the ethics of intimate relationships. It draws attention to the emotional labour involved in sustaining partnerships, the asymmetries of power and dependency that exist within many relationships, and the importance of attending to the particular needs of a particular partner rather than applying one-size-fits-all rules. It also raises critical questions about who bears the burden of care in relationships and whether that burden is distributed equitably.

In the domain of sexual ethics, care ethics complements consent-based frameworks by insisting that consent alone is not sufficient for ethical sexual interaction. A sexual encounter may be technically consensual yet still ethically deficient if one party is inattentive to the other’s comfort, pleasure, vulnerability, or emotional state. Ethical sex, from a care perspective, requires ongoing responsiveness, communication, and genuine concern for the other’s well-being.

1.6 Feminist Ethics

Feminist ethics is not a single theory but a family of approaches united by attention to gender, power, and the ways in which traditional moral philosophy has reflected and reinforced patriarchal assumptions. Feminist ethicists interrogate the supposed neutrality and universality of mainstream ethical theories, arguing that these theories were developed by men, in male-dominated institutions, and often implicitly assume a male subject.

1.6.1 Key Contributions of Feminist Ethics

Feminist ethics makes several important contributions to sexual and relational ethics:

• Power analysis: Feminist ethics insists that we cannot understand the ethics of sexuality and relationships without attending to structures of power—between genders, between sexual orientations, between economic classes, between races. What appears to be a free choice may be conditioned by systemic inequalities.
• Critique of the public/private distinction: Traditional liberal ethics treats the domestic and intimate sphere as “private” and therefore beyond the reach of ethical and political scrutiny. Feminist ethics insists that what happens in bedrooms and families is as much a matter of justice as what happens in legislatures and marketplaces. “The personal is political.”
• Intersectionality: Feminist ethics recognizes that gender oppression intersects with race, class, sexuality, disability, and other axes of marginalization, and that ethical analysis must attend to these intersections.
• Embodiment: Feminist ethics takes seriously the fact that moral agents are embodied beings, and that the body—its pleasures, vulnerabilities, reproductive capacities—is not ethically irrelevant.

1.6.2 Feminist Sexual Ethics

Feminist sexual ethics engages with questions about objectification, commodification of sexuality, pornography, sex work, reproductive autonomy, sexual violence, and the construction of sexual desire within patriarchal culture. A central feminist insight is that sexual norms are not natural or inevitable but are socially constructed and politically consequential. The regulation of women’s sexuality—through slut-shaming, purity culture, restrictive reproductive policies—serves to maintain patriarchal control, and challenging these norms is an ethical imperative.

At the same time, feminist sexual ethics grapples with internal tensions: between sexual liberation and protection from exploitation, between respecting women’s choices (including choices to engage in sex work or BDSM) and questioning whether those choices are truly free in a context of pervasive inequality. These tensions do not admit of easy resolution, and navigating them is one of the central challenges of the field.

Chapter 2: Autonomy, Relationality, and the Self

2.1 Individual Autonomy in Liberal Ethics

The concept of autonomy—literally self-governance—occupies a central place in modern Western ethics. In the liberal tradition, autonomy is understood as the capacity of individuals to make their own choices about how to live, free from coercion and undue interference by others or by the state. Respect for autonomy is the foundation of informed consent in medical ethics, contractual freedom in law, and the right to privacy in political theory.

In the context of sexual and relational ethics, autonomy grounds the principle that adults should be free to conduct their intimate lives as they see fit, provided they do not harm others. This principle supports the decriminalization of homosexuality, the legalization of same-sex marriage, the protection of reproductive rights, and the tolerance of diverse relationship structures. Autonomy-based arguments have been powerful tools for sexual liberation.

2.1.1 Limitations of the Individualist Model

However, the individualist conception of autonomy has significant limitations. It tends to imagine the autonomous agent as a solitary, rational decision-maker who arrives at choices through independent deliberation, uninfluenced by relationships, emotions, social contexts, or power structures. This picture is, as many critics have argued, a fiction—and a gendered, racialized, class-inflected fiction at that. The paradigmatic autonomous agent of liberal theory is implicitly male, white, propertied, able-bodied, and unburdened by care responsibilities. Real human beings are embedded in webs of relationship and dependency, and their capacity for autonomous choice is shaped by their social circumstances.

2.2 Relational Autonomy

Relational autonomy is an alternative conception developed by feminist philosophers, notably Catriona Mackenzie and Natalie Stoljar, that retains the value of self-governance while acknowledging its social conditions. Dove et al. (2017) argue that relational autonomy provides a more realistic and ethically richer framework for understanding decision-making in contexts where individuals are deeply interdependent.

2.2.1 Core Commitments of Relational Autonomy

Relational autonomy holds that:

1. Autonomy is socially constituted: The capacities required for autonomous choice—self-reflection, self-confidence, access to information, the ability to imagine alternatives—are developed through social relationships and can be undermined by oppressive social conditions.

2. Autonomy is exercised in relationship: Human beings do not make choices in isolation. Their decisions are made in dialogue with others, shaped by commitments to others, and have consequences for others. Recognizing this does not diminish autonomy but enriches it.

3. Autonomy requires enabling conditions: Genuine autonomy is not merely the absence of coercion but requires positive conditions—education, economic security, freedom from violence, access to healthcare, social recognition—that enable individuals to develop and exercise their capacities for self-governance.

2.2.2 Relational Autonomy in Sexual and Relational Contexts

Dove et al. (2017) argue that moving beyond individualism toward relational autonomy has important implications for how we understand consent, decision-making, and responsibility in intimate contexts. When we adopt a relational lens, we recognize that a person’s capacity to consent to or refuse sexual activity is shaped by their relationship history, their economic situation, their social support networks, their experience of violence or coercion, and the power dynamics within their current relationship. A purely individualist framework treats consent as a simple yes-or-no matter; a relational framework recognizes that consent exists on a spectrum of freedom and constraint.

This does not mean that relational autonomy undermines consent—quite the opposite. By taking seriously the conditions that make genuine consent possible, relational autonomy provides a more robust foundation for consent-based sexual ethics. It demands that we attend not only to whether consent was formally given but to whether the conditions for meaningful consent were present.

2.3 Unity and Difference in Relationships

One of the perennial ethical tensions in intimate relationships is between unity and difference—between merging with another person and maintaining one’s distinct identity. Romantic love, in particular, is often described in terms of union: “two becoming one,” completing each other, finding one’s “other half.” While these metaphors express something genuine about the experience of deep intimacy, they also carry ethical dangers.

When unity is pursued at the expense of difference, relationships become enmeshed: individual boundaries dissolve, one partner’s needs and identity are subsumed by the other’s, and the capacity for autonomous self-expression is lost. This dynamic is particularly concerning when it intersects with gender norms that encourage women to subordinate their identities to their male partners, or when it occurs in relationships characterized by coercive control.

A healthy ethical framework for intimate relationships recognizes both the value of deep connection and the importance of maintaining distinct identities. Partners can share a life without losing themselves; indeed, the richest relationships are often those in which both partners continue to grow as individuals while also growing together. Relational autonomy provides the theoretical resources for understanding this balance: autonomy is not threatened by intimacy but is exercised within intimacy when both partners support each other’s development and respect each other’s boundaries.

2.4 Equality, Equity, and Hierarchy

Another fundamental ethical dimension of relationships is the question of equality. The ideal of equality in intimate relationships—that partners should relate to each other as equals, with equal voice, equal respect, and equal power—is a relatively recent historical development. For most of human history, intimate relationships were explicitly hierarchical: husbands had legal and social authority over wives, parents over children, masters over servants.

2.4.1 Formal Equality vs. Substantive Equity

Even where formal legal equality has been achieved, substantive inequalities persist. Partners may be formally equal under the law but profoundly unequal in economic power, social status, physical strength, or emotional dependency. The concept of equity goes beyond formal equality to require that these substantive differences be acknowledged and addressed. An equitable relationship is not necessarily one in which everything is split fifty-fifty but one in which each partner’s contributions, needs, and vulnerabilities are recognized and responded to fairly.

2.4.2 Power Dynamics in Intimate Relationships

Feminist ethics directs attention to the ways in which broader social power structures—patriarchy, heteronormativity, racism, ableism, economic inequality—are reproduced within intimate relationships. A man may not consciously dominate his female partner, but if he earns more, does less housework, and assumes that his career takes priority, the relationship reflects and reinforces patriarchal norms. Recognizing and challenging these dynamics is an ongoing ethical task that requires self-awareness, honest communication, and willingness to change.

Hierarchy is not always oppressive. In some relationships, partners may freely and reflectively agree to power dynamics that are asymmetrical—as in consensual BDSM relationships or in relationships where one partner makes certain categories of decisions. The ethical question is not whether hierarchy exists but whether it is freely chosen, mutually understood, regularly renegotiated, and consistent with the dignity and well-being of all parties.

2.5 Stability and Change

Relationships exist in time, and one of their central ethical challenges is navigating the tension between stability and change. Commitment—the promise to remain in a relationship through difficulty and uncertainty—is widely valued, and for good reason: it provides security, enables trust, and makes possible the deep forms of intimacy that require time to develop. But commitment can also become rigidity, trapping people in relationships that no longer serve their flourishing or that have become harmful.

Ethical relational life requires the capacity to honour commitments while also remaining open to the reality that people change, circumstances change, and relationships must evolve. This means that promises of permanence—“till death do us part”—should be understood not as unconditional obligations but as expressions of serious intent that may, in some circumstances, ethically be revisited. The virtue of fidelity, properly understood, is not blind adherence to a commitment regardless of consequences but the disposition to take commitments seriously, to work at relationships, and to end them honestly and compassionately when they can no longer be sustained.

Chapter 3: Sexual Ethics

3.1 Why Sexual Ethics?

Carmody (2015) poses the question directly: Why do we need a specific ethics of sexuality? Why not simply apply general ethical principles to sexual contexts and be done with it? The answer lies in several features that make sexuality a distinctive ethical domain.

First, sexuality involves unique forms of vulnerability. In sexual encounters, people expose their bodies, their desires, their insecurities, and their emotional needs in ways that create particular risks of harm. The potential for physical injury, emotional devastation, disease transmission, and unwanted pregnancy makes sexual interactions high-stakes in ways that most other human interactions are not.

Second, sexuality is pervasively regulated by social norms that often have more to do with power, control, and tradition than with genuine ethical reasoning. Religious prohibitions, gender norms, heteronormative assumptions, racial stereotypes, and ableist attitudes all shape the landscape of sexual morality in ways that require critical examination.

Third, sexuality is deeply connected to identity. For many people, their sexuality is not merely something they do but something they are—a central dimension of their selfhood. Ethical judgments about sexuality therefore carry implications for judgments about persons, which raises the stakes considerably.

Carmody argues for an approach to sexual ethics grounded in ethical negotiation: the ongoing, communicative process through which sexual partners establish mutual understanding about desires, boundaries, and expectations. This framework goes beyond the minimalist “no means no” model of consent to require active, affirmative engagement with the question of what each partner wants and is comfortable with.

3.1.1 The Limits of “No Means No”

The “no means no” model, while an important advance over the outright denial of sexual autonomy, has significant limitations. It places the burden of refusal on the person who does not want a particular sexual act, rather than requiring the person who initiates to ascertain that their partner is an enthusiastic participant. It treats consent as a binary—given or withheld—rather than as an ongoing process that can be withdrawn at any time. And it focuses on preventing the worst outcomes (assault, coercion) while saying nothing about what constitutes good sexual interaction.

3.1.2 Affirmative Consent and Ethical Negotiation

The affirmative consent model (“yes means yes”) requires that all parties to a sexual encounter actively and clearly communicate their willingness to participate. This model better reflects the relational character of sexual interaction and distributes the responsibility for ensuring consent more equitably. Carmody’s concept of ethical negotiation goes further still, framing the communicative process around sex not as a burden or obstacle but as an integral part of respectful, pleasurable sexual interaction. On this view, talking about what one wants and does not want, checking in with a partner, and adjusting one’s behaviour in response to verbal and nonverbal cues are not interruptions of sexual pleasure but expressions of care and respect that enhance it.

3.2 Consent: Philosophical Foundations

Consent is arguably the most widely invoked concept in contemporary sexual ethics. Its philosophical foundations draw on several ethical traditions:

• Deontological foundations: Kant’s requirement to treat persons as ends, never merely as means, entails that sexual interaction without consent is a fundamental violation of human dignity. Consent transforms a potential use of another person into a mutual activity between free agents.
• Liberal foundations: The liberal commitment to individual liberty holds that adults should be free to do as they choose provided they do not harm non-consenting others. Consent delineates the boundary between permissible and impermissible sexual conduct.
• Contractual foundations: Some theorists model consent on the logic of contracts: parties negotiate terms, agree to them, and are bound by their agreement. This model has been criticized for being overly legalistic and for failing to capture the relational, emotional, and embodied dimensions of sexual interaction.

3.2.1 Conditions for Valid Consent

For consent to be morally valid, several conditions must be met:

3.2.2 Structural Constraints on Consent

Relational autonomy theory draws attention to the ways in which structural inequalities can compromise the conditions for valid consent even in the absence of overt coercion. Economic dependency, immigration status, institutional power (as between a professor and a student, an employer and an employee), and histories of abuse can all create contexts in which the formal conditions for consent are met but the substantive conditions—genuine freedom, real alternatives, adequate support—are not. Sexual ethics must attend to these structural dimensions rather than treating consent as a purely individual transaction.

3.3 Objectification and Commodification

Sexual objectification occurs when a person is treated as a mere object for another’s sexual pleasure, reduced to their body or body parts, stripped of subjectivity and agency. Feminist philosophers, notably Martha Nussbaum and Catharine MacKinnon, have analysed objectification as both a moral wrong and a pervasive feature of patriarchal culture.

Nussbaum identifies seven dimensions of objectification: instrumentality (treating a person as a tool), denial of autonomy, inertness (treating a person as lacking agency), fungibility (treating a person as interchangeable), violability (treating a person as something that may be damaged), ownership (treating a person as property), and denial of subjectivity (treating a person as though their experiences do not matter).

Not all of these dimensions are present in every instance of objectification, and Nussbaum acknowledges that some forms of objectification may be morally benign in the context of a loving relationship where autonomy and subjectivity are otherwise respected. The ethical concern arises when objectification is systematic, unilateral, and embedded in structures of inequality.

Commodification of sexuality occurs when sexual interactions or sexual attributes are treated as commodities to be bought and sold in a marketplace. Debates about sex work, pornography, and surrogacy centrally involve questions about whether and when the commodification of sexuality is ethically problematic. Liberal arguments hold that consenting adults should be free to exchange sexual services; feminist arguments raise concerns about whether consent is meaningful in a context where economic desperation and gender inequality drive many people into sex work.

3.4 Sexual Orientation, Gender Identity, and Ethics

Ethical questions about sexual orientation and gender identity have been central to public discourse for decades. The fundamental ethical question is whether there is any morally relevant difference between heterosexual and non-heterosexual orientations, or between cisgender and transgender identities. The major ethical traditions provide varying answers:

• Consequentialism finds no basis for moral condemnation of non-heterosexual orientations or transgender identities, since these do not inherently produce harm and can be sources of profound happiness and fulfilment.
• Deontology (at least in its Kantian form) treats all persons as having equal dignity regardless of their sexual orientation or gender identity; discrimination based on these characteristics treats people as less than fully human.
• Virtue ethics asks whether a person’s sexual orientation or gender identity is compatible with a flourishing life, and the evidence overwhelmingly indicates that it is—provided the person lives in a social environment that does not subject them to stigma, violence, and discrimination.
• Care ethics attends to the quality of care and connection in relationships regardless of the genders or orientations of the people involved.
• Feminist ethics critiques the heteronormative and cisnormative structures that marginalize LGBTQ+ persons and argues for the recognition and affirmation of sexual and gender diversity.

The ethical consensus in contemporary philosophy is clear: discrimination based on sexual orientation or gender identity is morally unjustifiable. The remaining ethical debates concern the pace and mechanisms of social change, the proper scope of legal protections, and the negotiation of conflicts between LGBTQ+ rights and claims of religious liberty.

Chapter 4: Relational Ethics — Infidelity, Monogamy, and Beyond

4.1 Infidelity as an Ethical Problem

Infidelity—broadly, the violation of an agreement of sexual or romantic exclusivity—is one of the most common and emotionally charged ethical problems in intimate relationships. Andersson (2022) explores how individuals in consensually non-monogamous relationships negotiate the concept of infidelity, revealing that the moral landscape of fidelity is far more complex than conventional norms suggest.

4.1.1 Why Infidelity Is Considered Wrong

Several ethical arguments converge on the wrongness of infidelity:

• Promise-breaking: If partners have explicitly or implicitly agreed to exclusivity, infidelity violates that agreement. Deontological ethics treats promise-breaking as intrinsically wrong; it damages the trust that is foundational to intimate relationships.
• Deception: Infidelity almost always involves deception—lying, concealment, misdirection. Deception violates the deceived partner’s autonomy by depriving them of information they need to make informed decisions about their own life.
• Harm: Infidelity typically causes profound emotional suffering to the betrayed partner, including feelings of inadequacy, humiliation, grief, and anger. Consequentialist ethics condemns it on these grounds.
• Breach of care: From a care ethics perspective, infidelity represents a failure of attentiveness and responsiveness to one’s partner’s needs and vulnerabilities.

4.1.2 Complicating the Picture

While the ethical case against infidelity within monogamous agreements is strong, several complexities deserve attention:

First, not all infidelity occurs in the same circumstances. There is a moral difference between a pattern of calculated deception and a single lapse of judgment; between infidelity that occurs in a context of mutual neglect and infidelity that violates an actively loving partnership; between infidelity that the unfaithful partner confesses and seeks to address and infidelity that is systematically concealed.

Second, the conventional focus on sexual exclusivity as the defining feature of fidelity can obscure other forms of relational betrayal. Emotional neglect, contempt, financial deception, and failure to share in the labour of maintaining a household and raising children can all constitute violations of the implicit agreements that sustain intimate partnerships, yet these are rarely discussed with the same moral urgency as sexual infidelity.

Third, as Andersson (2022) documents, the very concept of infidelity is historically and culturally variable. What counts as infidelity depends on what has been agreed, and these agreements are shaped by cultural norms, religious traditions, and individual negotiation.

4.2 Monogamy and Non-Monogamy

The ethical question of whether monogamy is morally superior to non-monogamy is distinct from the question of whether infidelity is wrong. One can maintain that breaking a monogamous agreement is wrong (because promise-breaking and deception are wrong) while also holding that there is nothing inherently wrong with non-monogamous relationship structures that are openly agreed upon.

4.2.1 The Ethics of Monogamy

Monogamy—the practice of having only one romantic and sexual partner at a time—is normative in most Western societies. Its ethical advantages include:

• Simplicity of expectations: Monogamy provides a clear framework of expectations that reduces ambiguity and the potential for misunderstanding.
• Depth of attachment: The exclusive focus on one partner may facilitate deeper emotional intimacy and investment.
• Security: The promise of exclusivity can provide a sense of security and stability that supports well-being.
• Social support: Monogamous relationships are supported by legal, social, and cultural institutions that provide material and symbolic benefits.

However, monogamy also carries ethical risks. It can foster possessiveness and jealousy; it can create unrealistic expectations that one person should meet all of another’s emotional, intellectual, sexual, and social needs; and when it is enforced through social pressure rather than freely chosen, it can constrain autonomy.

4.2.2 The Ethics of Consensual Non-Monogamy

Consensual non-monogamy (CNM) encompasses a range of relationship structures—polyamory, open relationships, relationship anarchy, swinging—in which partners agree that sexual or romantic involvement with others is permitted. Andersson (2022) examines how individuals in CNM relationships in Sweden negotiate the moral boundaries of their relationships, finding that these individuals do not reject the concept of infidelity but rather redefine it.

The ethical framework that emerges from studies of CNM relationships emphasizes process over structure. What matters is not the form of the relationship (monogamous vs. non-monogamous) but the quality of the ethical practices within it: honesty, transparency, ongoing negotiation, respect for boundaries, attentiveness to jealousy and insecurity, and equitable distribution of time and care.

4.2.3 Drawing the Line: Relationship Morality

Andersson’s research on “drawing the line at infidelity” reveals that all relationships, whether monogamous or non-monogamous, require moral boundary-work: the ongoing process of negotiating, articulating, and enforcing the norms that govern the relationship. This process is not a one-time event but an iterative practice that must respond to changing circumstances, evolving desires, and the introduction of new parties.

The ethical demands of this boundary-work are significant. It requires a high degree of self-knowledge (understanding one’s own desires, insecurities, and limits), communicative skill (the ability to articulate these to partners), emotional intelligence (the capacity to receive difficult information from partners without reacting destructively), and a commitment to fairness (ensuring that boundary-setting is mutual rather than one-sided).

4.3 Well-Being and Hardship in Relationships

All intimate relationships involve both well-being and hardship. The ethical question is not how to eliminate hardship—which is impossible—but how to navigate it in ways that are honest, compassionate, and consistent with the flourishing of all parties.

Well-being in relationships encompasses many dimensions: emotional intimacy, sexual satisfaction, companionship, shared purpose, mutual support, personal growth, and the feeling of being known and accepted. These goods are among the most significant sources of human happiness, and their absence is a significant source of suffering.

Hardship in relationships includes conflict, disappointment, boredom, jealousy, illness, financial stress, divergent life goals, and the inevitable friction of two (or more) distinct individuals attempting to share a life. The ethical question is not whether these difficulties will arise but how they will be addressed. Virtue ethics offers guidance here: the virtues of patience, forgiveness, honesty, and practical wisdom are essential tools for navigating relational difficulty. Care ethics adds the importance of attentive listening and responsive action. And feminist ethics reminds us that hardship is not equally distributed—women, people of colour, LGBTQ+ individuals, and economically disadvantaged people often bear disproportionate burdens within their relationships and deserve ethical attention to that inequity.

Chapter 5: Love, Friendship, and Family as Ethical Concepts

5.1 Love and Ethics

Love is one of the most powerful and pervasive human experiences, yet it receives surprisingly little systematic attention in mainstream moral philosophy. Ethics has traditionally been concerned with duty, rights, justice, and utility—concepts that seem, at first glance, to have little to do with the passionate, irrational, overwhelming experience of falling in love. But love is deeply ethical in at least three senses.

5.1.1 Love as an Ethical Orientation

To love someone is, at minimum, to care about their well-being, to be disposed to act for their benefit, and to take their interests seriously. Love thus generates ethical obligations: obligations of care, loyalty, honesty, and support. These obligations are not chosen in the way that contractual obligations are chosen; they arise from the relationship itself and from the emotional bonds that constitute it.

5.1.2 Love as a Source of Ethical Knowledge

Iris Murdoch argued that love—specifically, the loving, attentive perception of another person—is a form of moral knowledge. To truly see another person, to attend to them with care and without prejudice, is to apprehend moral reality in a way that abstract principle cannot achieve. Love teaches us about the particularity of other persons, the complexity of their situations, and the depth of their needs.

5.1.3 Love as an Ethical Challenge

Love also poses ethical challenges. It can be possessive, jealous, obsessive, and controlling. It can blind us to a partner’s faults or to the harm they do to us or others. It can create dependencies that undermine autonomy. The idealization of romantic love in Western culture can lead people to tolerate mistreatment, to sacrifice their own well-being, or to inflict suffering on others in the name of passion. An ethics of love must therefore be critical as well as celebratory, attentive to the ways in which love can go wrong as well as the ways in which it enriches human life.

5.1.4 Forms of Love

The ancient Greek vocabulary of love—eros (romantic, passionate love), philia (friendship love), storge (familial love), agape (unconditional, universal love)—provides useful distinctions. Each form of love generates distinctive ethical demands. Eros demands honesty about desire and respect for the beloved’s autonomy. Philia demands loyalty, reciprocity, and mutual respect. Storge demands care, protection, and the fostering of development. Agape demands compassion and concern for all persons, not only those to whom we are personally attached.

5.2 Friendship and Ethics

Friendship is a neglected topic in modern moral philosophy, though Aristotle devoted extensive attention to it in the Nicomachean Ethics. Aristotle identified three types of friendship: friendships of utility (based on mutual benefit), friendships of pleasure (based on shared enjoyment), and friendships of virtue (based on mutual recognition of and admiration for each other’s character). Only the last, Aristotle argued, constitutes true friendship.

5.2.1 Friendship as an Ethical Relationship

Friendships of virtue are ethically significant because they involve several features that are central to the moral life:

• Reciprocity: True friendship is mutual; both parties give and receive.
• Honesty: Friends are expected to be truthful with each other, including telling hard truths.
• Loyalty: Friends stand by each other in difficulty.
• Equality: Aristotle held that true friendship is possible only between equals—a claim that raises important questions about friendships across differences of power, status, and privilege.
• Mutual flourishing: The aim of true friendship is not merely mutual enjoyment but mutual development; friends help each other become better people.

5.2.2 The Ethics of Friendship in Contemporary Life

Contemporary ethical questions about friendship include: Do we have obligations to our friends that override our obligations to strangers? Is partiality toward friends morally justified, or does it conflict with the demands of impartial justice? How should we navigate friendships that cross boundaries of race, class, gender, and sexuality? What ethical obligations arise when a friendship ends?

These questions connect to broader themes in relational ethics. Care ethics validates the moral significance of particular attachments, arguing that we cannot and should not try to care for everyone equally; the depth and quality of our care for those close to us is a moral good in itself. Impartialist theories (utilitarian, Kantian) may be more sceptical of partiality but can accommodate it through arguments about the instrumental value of close relationships.

5.3 Family and Ethics

The family is perhaps the most ethically charged of all human institutions. It is the primary site of care, socialization, and identity formation; it is also a site of power, conflict, obligation, and, all too often, abuse. Ethical questions about the family are questions about who counts as family, what obligations family members owe each other, how family structures should be organized, and what role the state should play in regulating family life.

5.3.1 Diverse Family Forms

The nuclear family—two married heterosexual parents and their biological children—has never been the only family form, but it has been culturally privileged as the ideal. Ethical analysis must reckon with the diversity of actual family forms: single-parent families, blended families, multigenerational households, chosen families, families headed by same-sex couples, cohabiting partnerships without marriage, communal child-rearing arrangements, and more.

The ethical question is not which of these forms is “natural” or “traditional” (since the history of the family is one of tremendous variation) but which forms promote the flourishing of their members, particularly the most vulnerable members: children, elderly dependents, and those with disabilities.

5.3.2 Family Obligations

What do family members owe each other? This question generates significant philosophical debate. Some argue that family obligations are chosen—we voluntarily enter into intimate partnerships, and the obligations of those partnerships are analogous to contractual obligations. Others argue that many family obligations are unchosen—we do not choose our parents, siblings, or children (in the sense that we cannot predict who they will turn out to be), and the obligations that arise from these relationships are not reducible to voluntary agreement.

Care ethics provides a framework for thinking about family obligations that centres on need and vulnerability rather than choice and contract. Parents owe care to their children because children are vulnerable and dependent, not because the children consented to be born. Adult children may owe care to aging parents not because of a reciprocal contract but because of the history of care and connection that constitutes their relationship.

5.3.3 Power and Justice in Families

Feminist ethics insists that families are not havens from the political world but are themselves political institutions in which power is exercised, labour is divided, and justice or injustice prevails. The division of domestic labour, the allocation of financial resources, the distribution of decision-making authority, and the treatment of children are all matters of justice. A family in which one partner does all the housework and childcare while the other pursues career advancement is a family in which injustice is being done, regardless of whether both partners “agreed” to this arrangement—because such agreements are often shaped by gendered expectations and economic constraints.

Chapter 6: Queer Ethics and Families of Choice

6.1 Weeks, Heaphy, and Donovan: Same Sex Intimacies

Weeks, Heaphy, and Donovan (2001) in Same Sex Intimacies: Families of Choice and Other Life Experiments document and analyse the relational lives of non-heterosexual individuals in the context of rapid social change. Their work is both descriptive—reporting on how LGBTQ+ people actually organize their intimate lives—and normative, arguing that these “life experiments” have broader ethical significance.

6.1.1 Families of Choice

The concept of families of choice refers to the networks of intimate connection that LGBTQ+ people create when biological families reject them or when the nuclear family model does not fit their relational lives. Families of choice may include lovers, ex-lovers, close friends, and selected biological relatives. What defines them is not blood or legal ties but mutual care, commitment, and emotional significance.

Weeks et al. argue that families of choice are not merely substitutes for “real” families but are genuine forms of family that deserve ethical recognition and social support. They embody values—flexibility, negotiation, chosen commitment, egalitarianism—that are ethically admirable and that the broader culture might learn from.

6.1.2 The Ethics of Life Experiments

Weeks et al. use the phrase “life experiments” to describe the creative relational practices of LGBTQ+ people. These experiments include:

• Renegotiating the meaning of commitment: In the absence of (historically available) legal marriage, many same-sex couples developed forms of commitment that were based on ongoing choice rather than legal obligation. This required constant renegotiation and could not rely on institutional supports, making it in some ways more demanding but also more reflective and intentional.

• Redefining the boundaries of intimacy: LGBTQ+ relational practices often challenge the conventional boundaries between friendship, romance, and family. Ex-lovers may become close friends; friends may become co-parents; intimate networks may include people related by neither blood, sex, nor romance but by deep care and shared history.

• Creating egalitarian relationships: Weeks et al. find that same-sex couples, freed from the gendered scripts that organize heterosexual relationships, often develop more egalitarian arrangements for dividing domestic labour, making decisions, and managing finances. This does not mean that same-sex relationships are free from power dynamics, but it does mean that these dynamics must be negotiated rather than assumed.

6.1.3 Broader Ethical Significance

The ethical significance of families of choice and queer life experiments extends well beyond the LGBTQ+ community. They demonstrate that intimate relationships are not fixed by nature or tradition but are ongoing ethical projects that require creativity, communication, and care. They challenge the assumption that there is one right way to organize intimate life and suggest that the diversity of relational forms is itself an ethical good, enabling different people to find arrangements that support their flourishing.

At the same time, it is important not to romanticize these experiments. LGBTQ+ relationships exist in a context of homophobia, transphobia, and legal and social marginalization that creates distinctive burdens and vulnerabilities. The creativity of queer relational practices is, in part, a response to exclusion and adversity. Full ethical recognition requires not only celebrating the resilience and inventiveness of LGBTQ+ people but also dismantling the structures of injustice that make such resilience necessary.

6.2 Queer Theory and the Critique of Normativity

Queer theory provides a broader intellectual framework for understanding the ethical significance of non-normative sexualities and relationships. Queer theorists, building on the work of Michel Foucault, Judith Butler, and Eve Kosofsky Sedgwick, argue that sexual and gender categories are not natural or fixed but are socially constructed through discourse, institutions, and power relations.

6.2.1 Heteronormativity and Homonormativity

Heteronormativity is the set of cultural assumptions, institutional practices, and social norms that treat heterosexuality as the default, natural, and morally superior sexual orientation. Queer ethics challenges heteronormativity not merely by advocating for the inclusion of LGBTQ+ people within existing institutions (such as marriage) but by questioning whether those institutions are ethically sound in the first place.

This raises the question of homonormativity—the assimilation of LGBTQ+ people into mainstream heteronormative culture, including the adoption of monogamous marriage, nuclear family structures, and consumerist lifestyles. Some queer theorists argue that this assimilation, while securing important legal protections, comes at the cost of the radical ethical potential of queer life: the potential to model alternative forms of intimacy, community, and care that challenge the limitations of the heteronormative model.

6.2.2 Queering Ethical Theory

Queer ethics also challenges mainstream ethical theory. It asks: Whose experiences have been centred in the development of ethical theories? Whose have been excluded? What happens when we take the experiences of queer, transgender, non-binary, and intersex persons as starting points for ethical reflection rather than as marginal cases? The result is an ethics that is more attentive to diversity, more sceptical of universal claims, and more committed to justice for those at the margins.

Chapter 7: Educating on Sexual and Relational Ethics

7.1 Carmody’s Framework for Sexual Ethics Education

Carmody (2015) argues that conventional approaches to sexual education are inadequate because they focus primarily on risk reduction—preventing unwanted pregnancy, sexually transmitted infections, and sexual assault—rather than on cultivating the ethical capacities required for respectful, pleasurable, and mutually fulfilling sexual lives. While risk reduction is important, an education that addresses only risks and dangers produces a stunted understanding of sexuality, one that is fundamentally negative and fear-based.

7.1.1 From Risk Reduction to Ethical Practice

Carmody proposes a shift from risk reduction to ethical practice. This involves educating young people not merely about the mechanics of sex and the dangers of STIs, but about:

• Consent as an ongoing communicative practice, not a one-time event.
• Respect for diverse sexualities and gender identities, challenging homophobia, transphobia, and gender stereotyping.
• Critical analysis of sexual norms, including the ways in which media, pornography, and peer culture shape expectations about sex.
• Emotional literacy: the ability to identify, articulate, and manage one’s own emotions and to respond empathetically to the emotions of others.
• Ethical negotiation: the capacity to engage in honest, respectful conversation about desires, boundaries, and expectations.

7.1.2 The Role of Ethical Negotiation

Ethical negotiation requires several capacities that can and should be cultivated through education:

1. Self-knowledge: Understanding one’s own desires, boundaries, values, and vulnerabilities.
2. Communication skills: The ability to express desires and boundaries clearly and to hear and respect those of others.
3. Empathy: The capacity to imagine another person’s experience and to respond to their verbal and nonverbal cues.
4. Critical thinking: The ability to question received assumptions about sex, gender, and relationships and to reason independently about ethical questions.
5. Courage: The willingness to speak up about one’s boundaries and to challenge behaviour that one finds unethical, even in the face of social pressure.

7.2 Challenges in Sexual Ethics Education

7.2.1 Cultural and Religious Diversity

Sexual ethics education operates in a context of profound cultural and religious diversity. What is considered ethically appropriate sexual behaviour varies enormously across cultures and religious traditions. Educators face the challenge of respecting this diversity while also maintaining certain ethical non-negotiables—particularly around consent, non-violence, and non-discrimination.

One approach is to distinguish between thick and thin ethical principles. Thin principles—such as the prohibition of coercion and the requirement of consent—may command broad cross-cultural agreement. Thick principles—such as the value of premarital chastity or the superiority of monogamy—are culturally specific and should not be imposed through education. The task of sexual ethics education is not to promote a particular sexual morality but to cultivate the capacities for ethical reflection and negotiation that enable individuals to navigate the moral complexities of their own sexual and relational lives.

7.2.2 The Influence of Pornography and Media

A critical challenge for sexual ethics education is the pervasive influence of pornography and media representations of sexuality. For many young people, pornography is a primary source of information about sex—a source that typically presents sex as performance-oriented, male-focused, unrealistic in its depiction of bodies and desires, and devoid of emotional content or ethical consideration. Sexual ethics education must address this influence directly, helping young people to analyse media representations critically and to develop more realistic and ethical understandings of sexual interaction.

7.2.3 Addressing Power and Vulnerability

Effective sexual ethics education must attend to the realities of power and vulnerability in sexual contexts. Young people are not equally empowered; gender, race, class, disability, and sexual orientation all affect their capacity to negotiate sexual encounters. Education must acknowledge these inequalities and provide tools for navigating them, rather than assuming a level playing field.

7.3 Group Exhibits as Pedagogical Practice

Module 4 of this course involves student-led group exhibits on topics related to sexual and relational ethics. This pedagogical approach reflects several of the course’s commitments:

• Active learning: Students are not passive recipients of information but active constructors of knowledge.
• Collaborative inquiry: The group format requires students to negotiate among themselves about content, presentation, and perspective—modelling the ethical negotiation that is a central theme of the course.
• Public engagement: Presenting to an audience requires students to communicate complex ethical ideas clearly and accessibly, a skill that has value far beyond the classroom.
• Diversity of perspectives: Group exhibits allow a wider range of topics and perspectives to be explored than any single syllabus could cover.

The exhibit format also provides an opportunity for students to integrate the ethical theories and concepts from the first three modules and to apply them to specific, concrete topics of their choosing. This integration and application is the culmination of the course’s learning outcomes.

Chapter 8: Integrating Ethical Perspectives

8.1 Pluralism in Ethical Reasoning

One of the central lessons of this course is that no single ethical theory provides a complete account of sexual and relational morality. Each theory illuminates certain dimensions while leaving others in shadow:

• Consequentialism directs attention to outcomes—happiness, suffering, well-being—but can struggle with questions of rights, dignity, and fairness.
• Deontology provides strong foundations for consent and respect for persons but can be rigid and inattentive to context.
• Virtue ethics attends to character and flourishing but can be vague about specific action-guidance and can reflect culturally specific ideals of virtue.
• Care ethics foregrounds relationships, vulnerability, and emotional responsiveness but can undervalue justice and risk reinforcing gendered expectations about who should provide care.
• Feminist ethics attends to power and inequality but is a diverse field with internal disagreements about fundamental questions.

Ethical pluralism—the view that multiple ethical theories and perspectives are needed for adequate moral reasoning—is not a weakness but a strength. It reflects the genuine complexity of moral life and the diversity of values that are at stake in sexual and relational contexts.

8.2 Applying Multiple Lenses

Consider a concrete example: a married couple in which one partner wishes to open the relationship and the other does not.

• A consequentialist analysis would ask: What would produce the greatest overall well-being? Would opening the relationship increase or decrease happiness for both partners and any other affected parties?
• A deontological analysis would ask: Does either partner have a right to demand monogamy or non-monogamy? What does respect for each partner’s autonomy require? Is the original monogamous agreement morally binding?
• A virtue ethics analysis would ask: What would a person of good character do in this situation? What virtues—honesty, compassion, courage, fairness—are relevant, and what do they demand?
• A care ethics analysis would ask: What does attentive, responsive care require? How can each partner attend to the other’s needs, fears, and vulnerabilities? What would sustain the relationship as a caring connection?
• A feminist analysis would ask: Are there gendered power dynamics shaping this disagreement? Does one partner’s greater economic power or social capital give them an unfair advantage in the negotiation?

No single analysis provides a complete answer. But together, they illuminate the multiple dimensions of the ethical problem and provide a richer foundation for decision-making than any one theory alone.

8.3 The Practice of Ethical Reflection

Ultimately, sexual and relational ethics is not primarily an academic exercise but a practice—something one does, not merely something one studies. The theories, concepts, and frameworks explored in this course are tools for living, intended to be used in the ongoing work of navigating intimate relationships with integrity, care, and justice.

This practice involves several ongoing commitments:

• Self-examination: Regularly reflecting on one’s own values, assumptions, desires, and behaviour.
• Honest communication: Speaking truthfully to intimate partners about one’s needs, boundaries, fears, and failures.
• Active listening: Attending carefully to what partners say and do not say, and responding with empathy and respect.
• Willingness to be challenged: Remaining open to the possibility that one’s own views may be wrong or incomplete, and engaging seriously with perspectives that differ from one’s own.
• Commitment to justice: Working to ensure that one’s intimate relationships are fair, equitable, and free from domination.
• Compassion: Responding to one’s own and others’ failures with understanding as well as accountability.

These commitments do not guarantee that one’s relationships will be free from conflict, pain, or failure. But they make possible a quality of relational life that is honest, caring, and ethically reflective—and that, in the end, is what sexual and relational ethics is about.
