Ethics — Complete Study Notes

This unit examines moral consciousness — the inner sense of right and wrong every human being seems to carry — and asks what actually grounds it. It surveys the immediate "data" of moral experience, weighs Jean-Paul Sartre's atheistic existentialism as a rival account, and finally proposes human inter-relatedness (our being fundamentally social) as the real foundation of the moral order.

1.1 Moral Consciousness vs Moral Experience

Experience is whatever affects us — an emotion, an active or passive state, even a growth in knowledge ("noetic experience"). It leaves an imprint on us whether we notice it or not; much of it sits in the unconscious, quietly shaping behaviour. Consciousness is what happens when we become aware of this — when the implicit becomes explicit.

Human consciousness has different "fields," each defined by its own formal object (the thing it is fundamentally about):

1.2 The Data of Moral Consciousness

The most immediate fact of moral life is simply this: some actions are "good" (allowed) and some are "bad" (not allowed) — and human beings across every culture, throughout history, have made this distinction. This corresponds to the classic scholastic principle:

Reflection uncovers several further "data" (immediately given features) of this moral awareness:

• Gradation of obligation: among good actions, some must be done absolutely, some only conditionally (depending on person/time/place), and some are merely optional (though praiseworthy if done). The same three-fold gradation applies to actions to be avoided.
• The "Absolute Should": a felt sense of obligation or constraint — yet unlike physical force, it leaves us completely free to comply or not. This is moral freedom.
• Objectivity: this "should" is not something we invent for ourselves (unlike a promise we freely make); we find ourselves already obligated before we ever decide anything.
• Universality: if an action is an "absolute should" for me, it is a should for any person who understands the situation as I do — it applies to every human person, not just me.
• Rectitude as its own end: what is "right" should be done because it is right — not merely as a side-effect of some other (even good) motive.
• Satisfaction / guilt: we feel satisfaction when we do what we believe is right, and guilt when we don't — independent of others' praise or blame. This underlies our habit of holding ourselves and others responsible for actions.

1.3 The Foundation of the Moral Order

A moral value is a concrete "moral ideal" — human behaviour as it should be. The moral order is simply the totality of moral values. The central question is:

This single question actually hides two questions: a question of fact (is there such a foundation, and do people actually build on it?) and a question of right (should there be one?). Observation of history, sociology, and psychology could suggest human persons simply create their own values, conditioned by their group, culture, and customs — e.g., a head-hunting tribe's "ideal behaviour" is collecting enemy skulls. But note: even wildly divergent moral values could still rest on the same underlying foundation — just as two people motivated by the same love for a dying mother might choose opposite actions (prolonging life vs. permitting euthanasia).

1.4 Existentialist Humanism — Jean-Paul Sartre

Sartre is the philosopher who most sharply challenges the idea of an objective moral foundation. His position rests on his atheism: an objective foundation for values could only be a "realism of essences" created by God — but for Sartre, God does not exist.

Key Concepts: En-soi and Pour-soi

Because human beings have no pre-fabricated essence, "existence precedes essence." A person is not born with a fixed nature that determines what they will do — a person becomes what they make of themselves, in freedom. With no pre-existing norms to consult, human persons must — like artists inventing aesthetic values with no rulebook — invent their own moral values, so long as the invention is done in the name of freedom.

For Sartre, choosing freedom for oneself necessarily means acknowledging and choosing freedom for others too — this is why he insists his existentialism is a genuine humanism, not a selfish or nihilistic doctrine. But with no god to obey and no ready-made rules, the human person is, in Sartre's famous phrase, "condemned to be free" — alone in an absurd world, gripped by existential anguish.

A Critical Evaluation of Sartre

The unit raises an important objection: Sartre's ethical theory, pushed to its logical end, risks collapsing into moral anarchy — something even Sartre himself would not want. His refusal to define human nature in terms shared with all other people reflects a philosophically shaky nominalism. Still, one insight from Sartre is retained as valuable: moral values are indeed founded on the human person — just not on the isolated, purely individualistic person Sartre describes.

1.5 The Human Order and the Moral Order

Most of what we actually judge to be morally good or bad concerns our relations to other people. Even actions that seem to only concern God, the self (self-mutilation, suicide, drunkenness), or animals turn out — on reflection — to be qualifiable morally mainly because of their indirect effect on our relations with others (e.g., a drunkard's family suffers financially and emotionally).

What Is a "Person"?

An individual is simply a single, particular human being. A person, however, is something more specific: a human being essentially related to other human beings. This "relation to other men" — personhood — is not an accessory added on top of an already-complete human being; it is constitutive of human nature itself. The Aristotelico-Thomistic tradition long insisted that "human person is a social animal" — modern psychology and sociology have simply given this old insight new emphasis.

Why does this recognition matter? Because personhood is not something we already possess in isolation and then display to others — we need recognition by others to become fully aware of ourselves as persons. This is a double movement: myself as a person by others, and others as persons by me.

Love as the Foundation

The unit concludes by defining what it means, in this context, by love: not primarily the emotionally "charged" feeling, but the deliberate act of recognising and treating the other as a "subject" — a "person" with the same rights as I have.

The immediate ontological foundation of the moral order, then, is "human nature adequately considered" — that is, human nature understood in its totality of relationships, not as a static, isolated essence. This foundation leaves open (rather than closes) the further theological question of whether God is the ultimate foundation behind even this human inter-relatedness.

This unit builds Kant's deontological ethics step by step — from the Good Will, through the Categorical Imperative, to Freedom as a necessary postulate — and then explores the wider debate on human freedom and moral responsibility, contrasting determinism, indeterminism, Sartre's existential freedom, and finally Levinas' radical ethics of responsibility for the Other.

2.1–2.2 Kant's Rationalism and the Good Will

For Immanuel Kant, moral knowledge concerns what should be, not what is — so it cannot rest exclusively on experience. Moral precepts carry marks of necessity and universality, which are signs of being a priori (known independent of experience). Kant's task: isolate these a-priori elements within practical reason — reason directed not at knowledge but at moral choice.

Kant rejects finding the basis of morality in human nature, feelings, or society. For him, the ultimate basis of the moral law can only be pure practical reason itself — hence "Kant's rationalism."

2.3 The Categorical Imperative

Since universality is the "form" of the moral law, Kant translates this into a workable rule — the categorical imperative. It is "categorical" (unconditional) as opposed to "hypothetical" (conditional on some desired end, like popularity or wealth).

Notice the word "merely." Kant knows we cannot help using others' services to some extent — the imperative forbids treating people only as tools. Because human persons are ends in themselves capable of legislating moral law for themselves, Kant says the human will is autonomous — it gives itself the very law it obeys, rather than being dictated to by outside authority or desire.

2.4 Freedom as One of the Three Postulates

How is this a-priori imperative even possible? Kant finds the answer in freedom. In the Critique of Pure Reason, freedom could only be shown "negatively possible" (not self-contradictory) — but in the Critique of Practical Reason, Kant treats freedom as a practical necessity for the moral agent: a "condition of possibility" of the categorical imperative, even though it can never be theoretically proven.

This means the human person belongs not only to the phenomenal world (determined causality) but also to the noumenal world (freedom). Kant's supreme good requires two things together: virtue (will in accord with moral law) and happiness — but experience shows no guaranteed connection between the two. This gap leads Kant to posit two further postulates.

2.5 Human Freedom and Moral Responsibility

We saw in Unit 1 that "satisfaction" and "guilt" are immediate data of moral consciousness. Holding ourselves or others responsible for an action presupposes that the action was done freely — we can hardly blame someone for something they had no control over. So the very idea of responsibility connotes freedom.

This question of freedom shows up differently at three levels:

2.6 Determinism versus Indeterminism

2.7 Existential Situation and Human Freedom

For existentialists, morality is defined by each autonomous individual; the world itself is without inherent meaning ("absurd"), and any meaning must be put into it by the individual. Sartre — again the major protagonist — holds that human person is "condemned to be free" because there is no human essence prior to what one makes of one's existence (which would require a transcendent God, whom Sartre rejects).

2.8 Levinas' Philosophy of Responsibility for the Other

Emmanuel Levinas, a French-Jewish philosopher, makes ethics — not ontology (the study of being) — "first philosophy." He argues that grasping "the other" through concepts and categories (what he calls totalization) does violence to the other's genuine otherness.

Levinas criticises both Plato (whose doctrine of recollection reduces knowing to recalling what is already within the self) and his own teacher Husserl (whose intersubjective recognition still interprets the other only "in terms of my categories"). Even Heidegger comes under fire: Heidegger subordinates our relation with the Other to our relation with Being in general — which, Levinas warns, can lead to imperialist domination.

The Face of the Other

The face of the other calls me to responsibility — it "both calls forth and tears itself away from presence and objectivity." I can describe someone's physical features, but the face, properly understood, always exceeds any such catalogue. This encounter with irreducible otherness awakens the self (l'éveil du pour-soi) — but one cannot be responsible, even self-responsible, without the Other.

Because my very selfhood (Dasein) is accounted for by my relation to the other, ethics is prior to ontology — the ethical relationship comes before, and grounds, any philosophy of being.

Discourse ethics tries to establish right moral and political principles not by appeal to a fixed human nature or a private conscience, but by examining the presuppositions built into communication itself. This unit covers Kant's deontology as its prototype, then the two leading German proponents — Jürgen Habermas and Karl-Otto Apel.

3.1 What Is Discourse Ethics?

Discourse ethics holds that the "right" principles are those that would emerge from communication carried out under specified ideal conditions:

1. Parties regard each other as equals; equal regard is given to everyone's interests
2. There is an absence of constraint — direct force or indirect/structural pressure
3. The only admissible form of persuasion is rational argument
4. No assumption is immune to inquiry
5. Assumptions are accepted only if all parties agree
6. Communication is open-ended — no authority can declare an issue permanently settled

The first condition is a moral constraint; the rest are constraints of rationality. Real-world communication is never perfectly ideal, but envisaging what the outcome would be under such conditions helps us understand what the right principles are. This is also called argumentation ethics.

3.2 Kantian Deontological Ethics (Recap & Foundation)

Deontology comes from the Greek deon ("duty," "obligation," "moral necessity"). It holds that the correctness of an action lies within the action itself, not in its consequences — in contrast to teleological (consequence-based) ethics. Even if character assassination produced good results, a deontologist would still call it wrong.

Kant's "Universalisability Test": imagine what would happen if everyone did what you're considering doing. If we all stole from each other constantly, the very concept of "stealing" (which presupposes private property) would collapse into an "illogical black hole" — so stealing fails the test. Kant's moral law also demands: "So act as to treat humanity… always as an end, and never as only a means." Because of human dignity and the capacity to legislate as a moral agent in a "kingdom of ends," each person's duty consists in both the perfection of oneself and the perfection of others.

Discourse ethics, especially Habermas', is essentially an attempt to reformulate Kant's insights — replacing the private, "monological" reasoning of a solitary Kantian moral agent with the actual, public process of communicative argument.

3.3 Jürgen Habermas' Discourse Ethics

Habermas works within critical theory and pragmatism. He holds that pluralistic, polycentric societies inevitably generate disputes about norms — disputes that require participants to rise to a "post-conventional" level of moral consciousness. He prefers the label "discourse theory of morality," though "discourse ethics" has become the entrenched name.

Three General Features

Instrumental vs. Communicative Action

In Habermas' view, distorted communication allowed a few capitalists to subjugate the majority. He therefore envisions an ideal speech situation: complete absence of barriers to communicative exchange, all participants treated as dialogue partners with equal rights, and conclusions reached purely by the force of the better argument. Habermas is honest that this is not a realised situation — only a hoped-for possibility that favourable conditions could bring closer to reality.

This is Habermas' consensus theory of truth: a statement is true only if it earns the consent of everyone in the discussion, reached through the better argument within an ideal speech situation.

3.4 The Rules of Argumentation

Habermas argues that anyone who genuinely participates in argumentative speech and understands what it means to justify a norm must assume the validity of a principle of universalisability. The rules constituting an ideal "discourse" fall into two groups:

The remaining rules describe the "ideal speech situation" — the formal conditions under which rationally motivated agreement could be reached:

1. Everyone capable of speech and action ought to be allowed to participate in discourse
2. Everyone ought to be allowed to question any proposal
3. Everyone ought to be allowed to introduce any proposal into discourse
4. Everyone ought to be allowed to express their attitudes, wishes, and needs
5. No one ought to be hindered by compulsion — internal or external — from exercising the rights above

3.5 Moral Consciousness, Discourse Ethics & Kohlberg's Stages

Habermas builds on Lawrence Kohlberg's theory of moral development, which distinguishes six stages of moral judgment grouped into three levels:

Two elements matter most to Habermas here: (1) each stage requires learning — rebuilding earlier cognitive structures to meet new challenges; and (2) the stages form a hierarchy, where a higher stage "sublates" (preserves while reorganising) the lower one in a more differentiated form.

As children mature, their perspective evolves: from defining interests purely in relation to authority, to recognising others' interests, to seeing interactions as embedded in a wider social world of roles, and finally to justifying norms themselves from principles that reach beyond one's own social world — invoking an increasingly abstract "third party" perspective. This gradual shift is what Habermas calls the "naturalistic core… of moral consciousness."

3.6 Karl-Otto Apel's Discourse Ethics

Apel offers a modernised, transcendental version of Kant's philosophy, starting from the fundamental fact of language — the community of communication and discourse of which every human being is a member. He argues that all past moral theories were monological (results of a solitary thinker's private reflection), forgetting that even solitary thought only happens within a shared, communal language.

Reflecting on the transcendental conditions of discourse, Apel identifies four universal validity claims (borrowed from Habermas) built into every act of communication:

It is this fourth claim — the need for intersubjective validation — that grounds morality. To speak or argue at all is, in principle, to seek validation from the community of persons, implicitly acknowledging the equality and autonomy of all interlocutors. Respect for this community of persons is, for Apel, the transcendental condition of possibility of language and discourse itself — and therefore the foundation and ground of morality.

3.7 Apel's Critique of Previous Moral Theories

Apel argues that no past moral theory has adequately grounded a truly universal morality:

Apel's diagnosis: all past theories are monological — the product of a solitary thinker who forgets that all thought and reflection happens within, and is made possible by, a communal language. Only by starting from this linguistic condition can we find truly universal grounds for morality.

Apel's Transformed Categorical Imperative

Unlike Kant's private, "monological" universality, Apel's version demands the concrete universality of a real dialogue with those genuinely affected — representing all their true, legitimate interests, individually and collectively.

From Ethics of Intention to Ethics of Responsibility

Apel acknowledges a practical difficulty: in the real world, not everyone follows moral norms — some act on pragmatic or strategic principles instead (e.g., negotiators, national leaders). His answer avoids both naïve utopianism and amoral "real politik." We must:

• Respect the actual level of discourse and ethical life already achieved (laws, treaties, institutions)
• Make a constant effort to move progressively closer to the ideal community of communication

Human beings are, in Aristotle's phrase, "social and political creatures." This unit studies social institutions — the stable clusters of norms, values, structures, and roles ("the wheels on which human society marches on") — surveying sociological and philosophical accounts of what institutions are, their general properties, and their deep connection to rights, duties, and distributive justice.

4.1–4.2 What Is a Social Institution?

"Social institution" covers complex, self-reproducing social forms: governments, the family, human languages, universities, hospitals, business corporations, legal systems. Some influential definitions:

Philosophers care about institutions too — notably John Rawls, who developed elaborate theories of the justice that ought to govern them. Five major institutions are conventionally identified:

Institutions vs. Societies vs. Organisations

Institutions must be distinguished from simpler forms (conventions, norms, roles, rituals — which are their constitutive elements) and from more complete wholes such as societies (which are largely self-sufficient — they reproduce membership, have their own territory, culture, language, and economic/political independence, none of which a single institution needs).

Governments are a special case: meta-institutions — institutions whose function is largely to organise other institutions (economic systems, education, police, military) through legislation.

4.3 General Properties of Social Institutions

Four salient properties define an institution:

There can even be competing cultures within a single organisation — an "official" culture aligned with formal tasks and rules, versus an "unofficial" culture adhered to informally by a sub-group of the membership.

4.4 Three Theoretical Accounts: Atomistic, Holistic, Molecularist

4.5 A Teleological Account of Institutions

Teleology (Greek telos, "end," + logos, "science") explains and justifies values by reference to a final purpose. The central concept here is joint action: intentional individual actions of several agents directed at a shared collective end — an end possessed by each individual, yet realised only by the combined actions of all or most (e.g., two people lifting a table together).

Collective ends can be implicit (never explicitly formulated) or even latent (not currently being pursued, yet still remaining an end of the institution across generations). Social norms are regularities that also carry a felt "ought" — a duty to conform that goes beyond mere instrumental self-interest (though this "ought" is broader than, and not limited to, the specifically moral "ought").

Organisations and the "Layered Structure of Joint Actions"

Organisations (governments, universities, corporations, armies) are individuated by their characteristic ends — governments order and lead societies, universities discover and disseminate knowledge. A striking feature of organisational action is its layered structure: e.g., in a battle, the mortar squad destroying gun emplacements, air-cover, and infantry holding ground are each severally necessary and, together, jointly sufficient to defeat the enemy — constituting one overall joint action.

4.6 Normative Character of Social Institutions

Social institutions carry a multi-faceted normative dimension: human rights and duties, contract-based rights and obligations, and rights/duties arising from collective goods. Take the police: they protect people's human right to life/liberty and institutional right to property — distinctively through the use, or threatened use, of coercive force, which sets policing apart from most other institutions.

Institutional Moral Rights vs. Mere Institutional Rights

There are also joint moral rights — rights that attach to individuals but only jointly, e.g., joint owners of land together holding the right to exclude trespassers.

4.7 Social Institutions and Distributive Justice

Justice is central to evaluating most social institutions — market economies, wage structures, tax systems, judicial systems, prisons. It's important to keep three concepts distinct: justice, rights, and well-being. Genocide, for instance, violates the right to life but is not, strictly speaking, primarily an act of injustice in the narrow relational sense used here.

Distributive justice matters for most institutions because role-occupants are recipients/providers of benefits (wages, products) and bearers of burdens (tasks). Some institutions (arguably governments) have distributive justice as a defining function; others (like human language, defined around the end of truth) do not have justice as a defining feature at all.

The unit closes by extending this to the globalised economy: if citizens are committed, on moral grounds, to enforcing distributive justice within their own society (intra-societal), it is hard to see why they should not be equally committed to it in trans-societal economic relationships — e.g., multinational corporations paying fair wages that reflect a worker's real contribution, regardless of which country that worker is in.
