Francis Hutcheson: The Man Who Named the Moral Sense
In his correspondence Adam Smith reserved a particular epithet for exactly two men. One was David Hume. The other was his old professor at Glasgow, whom he called "the never to be forgotten Hutcheson." That is an extraordinary thing for the author of *The Wealth of Nations* to have written about a lecturer, and it points at something the published record only partly captures: Hutcheson's influence travelled through rooms as much as through books.
Drumalig, and a Presbyterian Inheritance
Hutcheson was born on 8 August 1694 at Drumalig, in the parish of Saintfield, County Down, in the Kingdom of Ireland. He was the son of a Presbyterian minister of Ulster-Scottish stock whose family came from Ayrshire — an Irish philosopher of Scottish descent, and the hybrid matters, because his entire career was conducted across that channel. He was educated at Killyleagh, then studied at the University of Glasgow from 1710 to 1718, taking in philosophy, classics, literature and theology and receiving his degree in 1712. He supported himself as tutor to the Earl of Kilmarnock. In 1725 he married his cousin Mary, daughter of Francis Wilson of Longford; of their seven children only one, Francis Hutcheson the younger, survived.
The Dublin Academy
From 1718 to 1729 Hutcheson ran a private academy in Dublin, assisted by Thomas Drennan — roughly a decade of teaching outside any university. It was in these years, and anonymously, that he published the work that made his name: *Inquiry concerning Beauty, Order, Harmony and Design* and *Inquiry concerning Moral Good and Evil*, both in 1725, alongside *Thoughts on Laughter* (1725) and the *Observations on the Fable of the Bees* (1725-27), followed by the *Essay on the Nature and Conduct of the Passions and Affections* and the *Illustrations upon the Moral Sense*, both 1728.
The Moral Sense
The doctrine at the centre of all of it is deceptively simple. Hutcheson defined a sense as "any determination of our minds to receive ideas independently on our will, and to have perceptions of pleasure and pain." He argued that alongside the five external senses humans possess an internal one that responds to actions as the eye responds to light — approving benevolence, recoiling from cruelty, immediately and without calculation. Moral judgment, on this account, is not the conclusion of an argument. It is a perception.
The target was Hobbes, and behind Hobbes, Mandeville. Where they derived all human conduct from self-interest, Hutcheson insisted that benevolence is an original and irreducible feature of human nature — not a disguised form of selfishness, not a habit imposed by education, but a fact about the equipment we are issued with. Only benevolent actions, he held, deserve moral approval at all.
The Greatest Happiness of the Greatest Number
Hutcheson also supplied the sentence. Long before Bentham built a system on it, he proposed as the test of a virtuous action its tendency to promote general welfare, formulating the principle of the greatest happiness for the greatest number. He extended moral consideration to animals on the same grounds — that sentient creatures can experience pleasure and pain, and that this, not rationality, is what makes a being morally considerable, an argument Bentham would restate decades later.
He was, in parallel, among the first modern philosophers to treat beauty as the object of an internal sense, noting "a natural power of perception or sense of beauty in objects, antecedent to all custom, education or example" while allowing for the role of association. In doing so he helped make aesthetics a distinct branch of philosophy rather than a corner of rhetoric.
The Chair at Glasgow
In 1729 he succeeded Gershom Carmichael as Professor of Moral Philosophy at Glasgow, taking up his duties in 1730 with an inaugural lecture, *De naturali hominum socialitate*. He was delighted to return: "I was, therefore, moved by no mean frivolous pleasure when I had heard that my alma mater had delivered me, its one time alumnus, into freedom." He was the first professor at Glasgow to lecture in English rather than Latin — a decision that sounds administrative and was in fact revolutionary, because it opened moral philosophy to anyone in the room rather than to those with a classical education.
His Glasgow publications included *Considerations on Patronage* (1735) and the textbooks *Philosophiae moralis institutio compendiaria* and *Metaphysicae synopsis* (both 1742). *A System of Moral Philosophy* appeared posthumously in two volumes in 1755, the *Reflections Upon Laughter* in 1750 and a *Compendium of Logic* in 1764. He died in Dublin on 8 August 1746 — his fifty-second birthday — and was buried at Saint Mary's churchyard.
Why Francis Is Called a Genius
Hutcheson's claim rests on identification rather than system-building. He isolated and named a faculty — the moral sense — that had not been given a clear place in the architecture of the mind, and in doing so reframed the central question of ethics from what reason commands to what human nature perceives. Everything downstream follows: Hume's separation of reason and sentiment in moral judgment is built on his analysis; Adam Smith studied under him and organised his own lectures, and the structure of *The Wealth of Nations*, along the lines of Hutcheson's *System*; the greatest-happiness formula passed to Bentham. Norman Fiering called him "probably the most influential and respected moral philosopher in America in the eighteenth century."
The deflationary reading has force. Scholars note that Smith's principal debt was to Hutcheson's magnetic personality and method of lecturing rather than to textual borrowing — which suggests the man was more remarkable than the argument. He wrote no single masterpiece; his most systematic work appeared after his death. His central doctrine drew durable rebuttal from Gilbert Burnet, John Balguy, John Taylor, Joseph Butler and above all Richard Price, who held that actions are right or wrong inherently and are perceived by the understanding, not by any sense. The fair verdict: not a first-rank system-maker, but the man who set the terms of the debate the Scottish Enlightenment then had.
Legacy
His reach ran further than his reputation. Francis Alison, his former student, taught three signers of the Declaration of Independence at the College of Philadelphia; John Witherspoon leaned heavily on Hutcheson at the College of New Jersey; John Adams read the *Short Introduction to Moral Philosophy* shortly after leaving Harvard. His association of unalienable rights with collective resistance to oppression entered American political vocabulary. Garry Wills argued in 1978 that the Declaration's phrasing owed largely to Hutcheson, a thesis Ronald Hamowy substantially criticised and Samuel Fleischacker partly defended. Between Locke's empiricism and the Scottish school of common-sense realism, he is the hinge — and modern arguments in aesthetics, utilitarian ethics and animal welfare all run back through a Presbyterian minister's son from County Down who insisted that a person who feels nothing at cruelty is missing a sense, not an argument.
