Francis Hutcheson (1694–1746)

Hutcheson argued that moral judgment is grounded in a “moral sense” — an internal faculty, analogous to the external senses, that perceives virtue and vice as naturally as the eye perceives colour. The proposal was directed against two positions: Hobbes’s egoism (all action is self-interested) and the rationalist ethics of Samuel Clarke (moral truths are known by reason alone). Against Hobbes, Hutcheson argued that benevolence is a real and irreducible motivation — that people genuinely care about the welfare of others, not merely about their own. Against the rationalists, he argued that moral distinctions are perceived, not deduced — that we feel the wrongness of cruelty as immediately as we feel the warmth of a fire. The moral-sense theory shaped the Scottish Enlightenment: Hume developed and modified it (replacing the moral sense with sympathy); Adam Smith extended it (through the impartial spectator). Hutcheson’s formulation — “that action is best which procures the greatest happiness for the greatest numbers” — anticipates Bentham’s utilitarianism by half a century.

Life

Born 8 August 1694 in Drumalig, County Down, Ireland, to a family of Scottish Presbyterian ministers. Educated at the University of Glasgow (1710–16). Ran a private academy in Dublin (1719–29), where he wrote his major philosophical works. Appointed professor of moral philosophy at the University of Glasgow (1730–46) — the chair he held until his death and from which he taught Adam Smith. Hutcheson was reportedly a charismatic lecturer who broke with tradition by lecturing in English rather than Latin; Smith later said the experience of Hutcheson’s lectures was formative.

Died 8 August 1746 in Dublin, on his fifty-second birthday.

The moral sense

An Inquiry into the Original of Our Ideas of Beauty and Virtue (1725) and An Essay on the Nature and Conduct of the Passions and Affections, with Illustrations on the Moral Sense (1728) develop the theory.

The moral sense as internal sense. Just as we have external senses (sight, hearing, touch) that perceive qualities in the physical world, we have an internal sense that perceives moral qualities in actions and characters. The perception is immediate — we do not deduce that cruelty is wrong; we see it, as directly as we see that a sunset is red. The moral sense approves of benevolence (actions aimed at the good of others) and disapproves of malice (actions aimed at harm). The perception is natural — all normally constituted human beings have it, just as all normally constituted human beings have sight.

Against Hobbesian egoism. Hutcheson devoted sustained argument to showing that benevolence is not reducible to self-interest. The parent who sacrifices for a child, the stranger who helps an injured person, the citizen who risks safety for the community — these are not disguised self-interest but genuine other-directed motivation. The moral sense perceives and approves this motivation directly.

The greatest-happiness formula. Hutcheson wrote: “That action is best, which procures the greatest happiness for the greatest numbers; and that, worst, which, in like manner, occasions misery.” The formula anticipates utilitarian ethics, though Hutcheson grounded it in the moral sense (we perceive that happiness-maximising actions are virtuous) rather than in rational calculation (Bentham’s approach).

Where Hutcheson stops

The moral-sense theory faces the diversity objection: if the moral sense is universal and natural, why do moral judgments vary across cultures? Hutcheson acknowledged variation but attributed it to differences in circumstance and information, not to differences in the moral sense itself — everyone has the sense, but what it is applied to varies. Whether this response is adequate — whether the degree of moral diversity across cultures can be explained by variation in circumstances alone, without variation in the faculty — is contested. Hume modified the theory by replacing the moral sense with sympathy (a more flexible and socially mediated mechanism), partly in response to this pressure.

The relationship between the moral sense and reason is underspecified. Hutcheson insists that moral perception is immediate — not a conclusion of reasoning — but he also allows that reason plays a role in determining the consequences of actions (which the moral sense then evaluates). Where the boundary between perception and inference falls — at what point moral judgment becomes calculation rather than perception — is unclear in Hutcheson’s account and was pressed by both Hume and the rationalists.
