There is a peculiar arrogance in youth: the quiet conviction that the world’s cruelty persists because those before us did not think clearly enough. One imagines that history is populated by the morally lazy, and that suffering might have been prevented had someone, somewhere, discovered the right principle. Behind this sentiment lies an ancient philosophical temptation - the hope that morality might admit of a formula. Is there a way to maximize happiness? A calculus of felicity? A method that could transform ethical life into something like applied mathematics?
This temptation animates the debate staged in Utilitarianism: For and Against, where J. J. C. Smart defends utilitarianism with disarming clarity and Bernard Williams interrogates the moral cost of that clarity. What emerges is less a dispute over conclusions than a struggle over how morality itself should be imagined.
Smart’s Intellectual Honesty
What I find compelling in Smart is not the doctrine itself, but the intellectual temperament behind it. He begins with suspicion - not toward morality, but toward the metaphysical debris surrounding it. Ordinary ethical thinking, he writes, is often “muddled, or else mixed up with questionable metaphysical assumptions” (p. 3). His ambition is austere: “It will be my object in the present study to state a system of ethics which is free from traditional and theological associations” (p. 4).
This aspiration resonates with a modern philosophical sensibility: a desire to think ethically without metaphysical consolation. If morality is to survive the collapse of theological certainty, perhaps it must learn to walk on empirical legs. In this sense, Smart’s utilitarianism appears almost as an ethical naturalism - morality reconstructed under the sign of scientific sobriety.
Yet even here the ground trembles. Smart confronts the classic divide between act- and rule-utilitarianism, only to dissolve it. An adequate rule-utilitarianism, he argues, would collapse into a single rule: the act-utilitarian one—“maximize probable benefit” (p. 12). What appears as pluralism reduces to unity. Morality contracts into a single imperative: optimize outcomes.
There is something both liberating and unsettling in this reduction. Liberating, because it promises clarity. Unsettling, because it strips morality of its familiar textures—duties, prohibitions, sacred boundaries - and replaces them with a single algorithmic demand.
Moral Language Without Metaphysics
Smart’s non-cognitivist leanings sharpen this austerity. Moral language, on his account, is less about truth than about commendation. “The function of the words ‘ought’ and ‘good’ is primarily to express approval… With ‘ought’ we commend actions… with ‘good’… states of affairs or consequences of actions” (p. 13).
Here I hesitate. For if moral language is primarily expressive, then utilitarianism becomes less a discovery than a decision - a commitment masquerading as neutrality. The system collides, as Smart himself admits, with “ultimate attitudes.” We may agree about consequences and still diverge about what ultimately matters.
Perhaps this is the first fracture in the dream of moral calculation: the recognition that no ethical system floats free from evaluative gravity.
The problem deepens once we ask what exactly is to be maximized. Smart’s reflections on pleasure are more subtle than caricatures of utilitarianism suggest. He distinguishes contentment from pleasure: contentment may be mere absence of unsatisfied desire, whereas pleasure involves a more positive equilibrium. “Pure unconsciousness would be a limiting case of contentment, but not of pleasure. A stone has no unsatisfied desires, but then it just has no desires” (pp. 16–17).
This passage lingers with me. It reveals a utilitarianism struggling against its own abstraction. Happiness cannot be reduced to a void of suffering; it must retain some positive density.
From here, qualitative distinctions emerge. Not all pleasures are equal - not intrinsically, but through their consequences. Some are fecund. The pleasures of poetry, Smart notes, are “more fecund than those of pushpin” (p. 16). Intellectual and aesthetic experiences generate further goods: sensitivity, imagination, moral depth. Other pleasures, he suggests, may be sterile or even corrosive.
Yet the argument carries an unintended confession. If higher pleasures matter because they cultivate richer forms of life, then utilitarianism quietly imports a vision of human flourishing it cannot fully justify. The calculus begins to smuggle in anthropology.
The electrode fantasy exposes this tension. Suppose humans could live in permanent states of stimulation - content, even delighted. We might grant that such beings are satisfied, yet recoil from calling them happy. Smart acknowledges this unease: happiness is “mainly descriptive but also partly evaluative,” making the maxim “You ought to maximize happiness” doubly evaluative (p. 24). The calculus depends on values it cannot compute.
Aggregation and Its Shadows
Once happiness becomes the currency of morality, questions proliferate. Should we maximize total happiness or average happiness? Should we follow the negative utilitarian suggestion - associated with Popper - that we minimize suffering rather than maximize happiness (p. 28)? Smart observes that people agree more readily about miseries to avoid than goods to promote (p. 30). Pain is democratic; happiness is plural.
But the deeper difficulty is distributive. The calculus asks: which course of action makes mankind happier on the whole? Yet the phrase “on the whole” already conceals a moral gamble. It risks dissolving individuals into aggregates. A world of profound injustice might still qualify as morally optimal if its totals are high enough.
Smart attempts to soften this by appealing to fairness in Mill’s sense. But the tension persists: equity appears as a constraint imported from outside the calculus, not generated by it.
Still, I am struck by Smart’s modesty. He does not pretend that utilitarianism harmonizes with all our intuitions. Rather, he presents it as a tool for deliberation. Moral theories, he suggests, are most needed when we must decide consciously - when habit fails. “The actions for whose rightness we as agents want a criterion are… those done thinkingly and deliberately” (pp. 45–46).
This pragmatic framing gives utilitarianism a certain dignity. It is less a metaphysical doctrine than a decision procedure for moments of moral vertigo.
The Moral Psychology of Optimization
Smart extends evaluation beyond actions to agents and motives. “A good agent is one who acts more nearly in a generally optimific way than does the average one … A good motive is one which generally results in beneficent actions” (p. 48).
Here utilitarianism reveals its austere anthropology. Moral worth becomes statistical reliability. The saint and the well-trained bureaucrat begin to resemble one another. Virtue dissolves into optimization.
And yet Smart ends on a note I find almost moving. No ethical theory, he concedes, will sit comfortably with all our attitudes. But utilitarianism, with its empirical flexibility, aligns with the “scientific temper.” It is a morality for a changing world - provisional, revisable, unsentimental. One senses both courage and loss in this vision.
Williams and the Revolt of the Person
If Smart embodies the modern will to clarity, Williams embodies its resistance. He does not merely dispute utilitarian answers; he questions its entire moral optics. The first philosophical question, he suggests, is not whether we accept utilitarian conclusions, but whether we accept its way of seeing (p. 78).
Williams describes Smart’s view as a direct, eudaimonistic consequentialism (p. 79). But where Smart speaks of happiness, Williams prefers the cooler language of utility - perhaps already a sign of distance. His central concern is integrity.
Why, Williams asks, should an individual bear responsibility for outcomes he did not initiate but could prevent? The familiar trolley cases are not puzzles but symptoms. Utilitarianism seems to erase the distinction between doing and allowing. It demands that I regard my own moral boundaries as negotiable variables in a global optimization problem (pp. 108ff).
Here the theory ceases to feel merely demanding; it begins to feel invasive. For our projects, convictions, and refusals are not detachable preferences. They are threads in the fabric of the self. To demand their sacrifice is not merely to ask for altruism - it is to threaten identity.
Williams also exposes a psychological cost. A moral outlook that evaluates everything from the standpoint of aggregate outcomes risks alienating agents from their own actions. Smart’s “causal theory of moral comment,” he argues, lacks openness and makes it difficult for a person to understand his own conduct (p. 124). One begins to see oneself from the outside, as if one were a replaceable instrument.
At the political level, Williams’ critique sharpens into indignation. Utilitarianism, he claims, appears “absurdly primitive” when confronted with real questions of justice and distribution (p. 142). The complexity of political life—its histories, inequalities, and claims of legitimacy - resists reduction to a single maximizing principle. In the face of political reality, he concludes, utilitarianism’s simplicity “disqualifies it totally” (p. 150).
A Tension Without Resolution
Where does this leave us? I find myself unable to dismiss either voice. Smart reminds me that suffering is not sacred, that consequences matter, that morality cannot live on metaphysical nostalgia. His utilitarianism speaks to a modern conscience unwilling to ignore preventable misery.
And yet Williams reminds me that a morality that sees everything may understand nothing. A life reduced to variables in a calculus ceases to be lived from within. Integrity - this stubborn, unquantifiable center of the person - resists aggregation.
Perhaps the youthful dream of a moral formula fails not because the aspiration to reduce suffering is misguided, but because morality inhabits two registers at once. From the outside, we see totals, outcomes, humanity. From the inside, we see commitments, boundaries, selves.
Utilitarianism gives voice to the first perspective with unmatched clarity. Williams gives voice to the second with unmatched depth. Between them stretches a philosophical tension that refuses resolution.
And perhaps this is where philosophy must remain: not in the comfort of synthesis, but in the honesty of fracture. For the desire to calculate happiness and the need to preserve integrity are not errors to be corrected. They are rival truths, and we live in their unresolved interval.
