Pleasure and Pain

Plato refuses both the hedonist and the ascetic. In the Philebus, Socrates stages a contest between pleasure and intellect for the title of the good, and the verdict is that neither alone is sufficient. The good life is a mixture, but it is not an equal mixture. Wisdom, measure, and truth rank higher than pleasure, and the pleasures admitted into the good life must be "pure," free from the admixture of pain that accompanies bodily desire. The pleasure of learning, of contemplating beauty, of mathematical insight: these count. The pleasure of scratching an itch does not.

The Gorgias sharpens the attack on hedonism. Callicles argues that the good life is one of maximum appetite and maximum satisfaction, and Socrates demolishes this with a series of analogies. The man who is always thirsty and always drinking is not happy but sick. Pleasure that depends on a prior state of lack is a symptom of deficiency, not a sign of flourishing. The tyrant who indulges every desire is the most enslaved man in the city.

In Republic Book IX, Plato ranks the pleasures of the three parts of the soul. The philosopher's pleasures are the truest because they correspond to stable realities; the appetitive pleasures are the least real because their objects are constantly shifting. Pleasure, properly understood, tracks the order of being.

Plato set the terms for every later debate: which pleasures are real, which are illusory, and whether pleasure as such can be the measure of a good life.

Aristotle devotes two full treatments to pleasure in the Nicomachean Ethics, one in Book VII and another in Book X, and commentators have debated their consistency ever since. The core insight is constant: pleasure is not a process but something that accompanies and completes an activity. Sight is pleasant when the eye is healthy and the object beautiful. Thinking is pleasant when the mind is sharp and the problem worthy. Pleasure, as Aristotle memorably puts it, is like the bloom of youth, something that comes upon the activity when both agent and object are in good condition.

This means there is no single thing called "pleasure." The pleasure of philosophical contemplation and the pleasure of eating differ not just in degree but in kind, because the activities they complete differ in kind. Some pleasures are proper to good activities and therefore good; others are proper to base activities and therefore bad. The hedonist's error is to treat pleasure as a uniform quantity to be maximized, when in fact the quality of a pleasure depends entirely on the quality of the activity it crowns.

Temperance, for Aristotle, is the virtue that governs bodily pleasures specifically. The temperate person enjoys food, drink, and sex in the right amounts, at the right times, in the right way. This is not suppression of pleasure but its proper ordering. The intemperate person is not someone who feels pleasure but someone who feels the wrong pleasures, or the right pleasures in the wrong measure.

Aristotle's distinction between pleasures by quality, not just quantity, would resurface two thousand years later in Mill's defense of higher pleasures.

Lucretius transmits Epicurean hedonism in its most eloquent form, and the doctrine is subtler than its reputation. The goal of life is pleasure, yes, but pleasure understood as the absence of pain in the body and disturbance in the mind. This is ataraxia, tranquility, and it is achieved not by pursuing intense sensations but by eliminating unnecessary desires. Nature asks very little of us: freedom from hunger, thirst, cold. Everything beyond this is added by opinion, by the restless craving for novelty that keeps men anxious and unsatisfied.

Book II opens with the famous image of watching a storm at sea from the safety of shore. The pleasure is not in the suffering of others but in the awareness of one's own security. This is the model for all Epicurean pleasure: it is defined by contrast with pain, by the relief of knowing that you are not subject to the torments that afflict the ignorant. The pleasures of philosophy, friendship, and simple living are "unmixed" because they carry no inevitable hangover, no cycle of craving and satisfaction.

Book IV tackles sexual desire as the paradigm of mixed pleasure. Lovers are perpetually frustrated because the body can never fully possess what it wants. The Epicurean prescription is not celibacy but detachment: enjoy the body's pleasures without the delusion that they will bring lasting happiness.

Lucretius gave later hedonists their most potent argument: that the pursuit of pleasure, rightly understood, is also the avoidance of misery.

Epictetus, born a slave, offers the most radical position in the tradition: pleasure and pain are not goods and evils at all. They are "indifferent," things that happen to the body and are outside our control. The only true good is the correct use of impressions, the rational faculty's power to assent or withhold assent from the appearances that strike us. A pain in the leg is a sensation; the judgment "this is terrible" is an act of the will, and it is the judgment, not the sensation, that disturbs us.

The Enchiridion opens with the famous division: some things are up to us (our opinions, intentions, desires, aversions) and some are not (our bodies, possessions, reputations, offices). Pleasure and pain fall squarely in the second category. To pursue pleasure or flee pain as though they were the most important things is to enslave yourself to what you cannot control. The Stoic sage may experience pain, but he does not suffer, because he withholds the judgment that pain is evil.

This is not mere indifference. Epictetus acknowledges that pain is "contrary to nature" in a limited sense, but he denies that anything contrary to nature can be a genuine evil for a rational being whose nature is reason. The sick man who maintains his rational composure is healthier, in the way that matters, than the athlete who panics at a scratch.

Epictetus gave Kant and the anti-hedonist tradition their strongest weapon: the insistence that moral worth lies in the will, not in feeling.

Aquinas treats pleasure and pain with the analytical precision of a naturalist classifying specimens. In Questions 31 through 39 of the Summa Theologica I-II, he distinguishes pleasure (delectatio) from joy (gaudium), and bodily pleasure from intellectual delight. Pleasure, he says, is a movement of the sensitive appetite when it rests in a suitable good; joy is its counterpart in the rational appetite. Pain (dolor) and sorrow (tristitia) are the corresponding movements when the appetite encounters evil. Every pleasure and pain is, in this framework, a response to a perceived good or evil, not a brute sensation.

This matters because it means pleasure and pain are always about something. They track the soul's assessment of its situation. Bodily pleasure signals that the body has obtained something it needs; intellectual joy signals that the mind has grasped truth. But neither pleasure nor pain is self-validating. A man may take pleasure in sin, and that pleasure is bad, not because the feeling itself is sinful but because it is directed at a disordered object. Conversely, sorrow over one's sins is a good sorrow, because it is directed at a genuine evil.

Aquinas follows Aristotle in holding that pleasure naturally accompanies virtuous activity. The temperate person enjoys moderate eating, and this enjoyment is a sign of genuine virtue. But pleasure is never the reason for virtue. The virtuous person acts for the sake of the good, and pleasure follows as a natural consequence, never as a motive.

Aquinas insists that pleasure is never merely a feeling but always a response to a perceived good — which means the quality of the pleasure tracks the quality of its object. What he cannot explain is why people reliably take pleasure in the wrong things: the disorder is not in the feeling but in the judgment. That gap between feeling and correct assessment of the good is precisely what Hobbes will close by denying the distinction: good just is whatever you in fact desire.

Hobbes strips the traditional language of good and evil down to its mechanical basis. In Chapter 6 of the Leviathan, he defines good as whatever is the object of desire and evil as whatever is the object of aversion. Pleasure is the appearance of good, the sensation that accompanies the satisfaction of desire; pain is the appearance of evil. There is no good or evil independent of what particular people want and avoid. This is not a theory about the highest good. It is a denial that any such thing exists.

The psychological picture is deliberately simple. Human beings are engines of desire. We move toward what pleases us and away from what pains us, and all the complex passions, love, hate, hope, fear, ambition, envy, are variations on this basic mechanism. Even seemingly selfless actions reduce, in Hobbes's account, to calculations of pleasure and pain. The charitable man gives because giving pleases him; the brave soldier fights because the pain of dishonor exceeds the pain of the wound.

Hobbes's reduction is bracing and intentionally provocative. He knows that it offends the Aristotelian tradition, which distinguishes noble pleasure from base pleasure, and the Christian tradition, which places the good beyond mere desire. But Hobbes insists that these traditions are describing the same mechanism in flattering language. When a philosopher calls some pleasures "higher," he is expressing his own preference, not discovering a fact about nature.

Hobbes makes hedonism respectable in modern philosophy by making it mechanistic — but he purchases clarity at the cost of any distinction between better and worse pleasures. Locke will immediately try to reintroduce that distinction through the concept of "uneasiness," and Mill will reconstruct it on qualitative grounds, yet both will find that Hobbes's leveling move keeps returning: if good just is what is desired, the higher pleasures may be nothing more than the preferences of people who happen to be educated.

Locke accepts from Hobbes the premise that pleasure and pain drive human action, but he develops it with greater psychological sophistication. In the Essay, Book II, Chapters 20 and 21, he catalogues the passions as so many modes of pleasure and pain: love is pleasure attached to an object, hatred is pain attached to one, desire is uneasiness in the absence of a good, joy is delight in a present good. The entire emotional life of a human being can be mapped onto these two fundamental experiences.

Locke's most original contribution is the concept of "uneasiness." It is not the promise of future pleasure that moves us to act, he argues, but the present discomfort of lacking something. The hungry man is motivated not by the idea of satisfaction but by the gnawing of his stomach. This has important consequences: it means that we are more reliably driven by the pain of want than by the attraction of good, and that moral education must attend to what people feel they lack, not only to what they desire.

Locke also insists that pleasure and pain are God's instruments for guiding us toward our preservation and well-being. They are natural signs, built into the human constitution, pointing toward what is beneficial and away from what is harmful. But Locke is no crude hedonist. He acknowledges that the greatest pleasure is the contemplation of God and that prudent self-governance requires resisting immediate pleasures for the sake of long-term good.

Locke's account of uneasiness as the primary motive creates an asymmetry that neither the utilitarian nor the Kantian tradition ever fully resolves: if we are more reliably driven by the pain of want than by the attraction of good, then moral life is essentially reactive, a matter of managing deficiency rather than pursuing flourishing. Kant will respond by insisting that the moral law must be legislated by reason independently of any felt need — that a morality grounded in uneasiness is not morality at all but prudence.

Kant launches the most sustained assault on hedonism in the history of philosophy. His target is the entire tradition running from Hobbes through Locke: the claim that pleasure and pain are the foundations of morality. If the moral law is grounded in pleasure, Kant argues, then it is grounded in something contingent, variable, and subjective. What pleases one person disgusts another. What pleases me today may bore me tomorrow. No universal law can be built on such shifting sand.

The Groundwork introduces the decisive distinction between acting from inclination and acting from duty. A shopkeeper who gives correct change because cheating would hurt his business acts from inclination; his honesty has no moral worth. Only the person who acts from duty, because the moral law commands it, regardless of whether it brings pleasure or pain, acts morally. Kant does not deny that pleasure sometimes accompanies dutiful action. He denies that the pleasure is what makes the action good. If anything, the highest moral worth belongs to the person who does the right thing despite finding it painful.

The Critique of Practical Reason develops this into a systematic rejection of all "material" principles of morality, every system that makes the rightness of an action depend on its consequences for pleasure and pain. Kant calls such systems "heteronomous" because they make the will a servant of desire rather than a legislator of law. Freedom, for Kant, means acting on principles that reason gives itself, not on impulses that nature inflicts.

Kant drew the permanent battle line: morality either rests on pleasure or on duty, and the two foundations yield irreconcilable systems. Mill accepted the challenge.

Mill defends hedonism against Kant by transforming it. Bentham had argued that pleasure is pleasure, differing only in quantity: intensity, duration, certainty, nearness. Mill breaks with his teacher on exactly this point. Pleasures differ in quality as well as quantity, and the higher pleasures of intellect, feeling, and imagination are categorically superior to the lower pleasures of bodily sensation. The person who has experienced both kinds and prefers the higher is the competent judge, and his verdict settles the matter.

This move rescues utilitarianism from Kant's charge of vulgarity, but it introduces a tension that Mill never fully resolves. If quality of pleasure is determined by the judgment of competent observers, then pleasure is no longer a simple, measurable quantity. It becomes something closer to Aristotle's eudaimonia, an assessment of the whole quality of a life. Mill seems aware of this. His famous declaration that it is better to be Socrates dissatisfied than a fool satisfied concedes that the good life may involve more pain than a lesser life, so long as its pleasures are of the right kind.

Chapter 4 of Utilitarianism contains Mill's proof, or attempt at proof, that pleasure is the only thing desirable as an end. Each person desires his own happiness; therefore happiness is a good; therefore the general happiness is a good to the aggregate of persons. The argument has been criticized as a fallacy, but its ambition is clear: Mill wants to ground all of ethics on the single observable fact that human beings seek pleasure and avoid pain.

Mill gave hedonism its most sophisticated modern form. Every subsequent utilitarian must decide whether his qualitative distinction holds or whether it quietly abandons the hedonist premise.

Freud takes the hedonist tradition and turns it inside out. He begins, in his early work, with what looks like orthodox hedonism: the mind operates according to the pleasure principle, seeking to reduce tension and avoid unpleasure. Desire builds up as a kind of psychic pressure, and satisfaction discharges it. The infant at the breast, the dreamer fulfilling a wish, the neurotic repeating a symptom all obey the same law. So far, Hobbes and Locke would recognize the picture.

But Beyond the Pleasure Principle (1920) introduces a disturbance that the tradition never anticipated. Freud observes that patients in analysis compulsively repeat traumatic experiences, returning again and again to scenes of pain. This repetition compulsion cannot be explained by the pleasure principle, since the repeated experience brings no satisfaction. Freud postulates a force more primitive than pleasure: the death instinct, a drive toward the dissolution of life, a return to the inorganic state from which all organisms emerged. The pleasure principle, it turns out, serves the death instinct by reducing tension toward zero.

Civilization and Its Discontents draws the social consequences. Civilization requires the renunciation of instinctual pleasure, and this renunciation produces guilt, aggression, and neurosis. The pain of civilized life is not an accident but a structural feature. Freud's conclusion is bleaker than anything in the philosophical tradition: we cannot organize society around the maximization of pleasure, because the very mechanisms that make society possible demand the suppression of pleasure.

Freud closed the ancient conversation about pleasure and pain by revealing depths beneath it that the philosophers had not suspected. After him, no account of human motivation can rest on the simple opposition of pleasure and pain.
