TUCKER, ABRAHAM (1705-1774), English moralist, was born in London, of a Somerset family, on the 2nd of September 1705, son of a wealthy city merchant. His parents dying during his infancy, he was brought up by his uncle, Sir Isaac Tillard. In 1721 he entered Merton College, Oxford, as a gentleman commoner, and studied philosophy, mathematics, French, Italian and music. He afterwards studied law at the Inner Temple, but was never called to the bar. In 1727 he bought Betchworth Castle, near Dorking, where he passed the remainder of his life. He took no part in politics, and wrote a pamphlet, " The Country Gentleman's Advice to his Son on the Subject of Party Clubs " (1755), cautioning young men against its snares. In 1736 Tucker married Dorothy, the daughter of Edward Barker of East Betchworth, cursitor baron of the exchequer. On her death in 1754, he occupied himself in collecting together all the letters that had passed between them, which, we are told, he transcribed twice over under the title of " The Picture of Artless Love." From this time onward he occupied himself with the composition of his chief work, The Light of "Nature Pursued., of which in 1763 he published a specimen under the title of " Free Will." The strictures of a critic in the Monthly Review of July 1763 drew from him a pamphlet called Man in Quest of Himself, by Cuthbert Comment (reprinted in Parr's Metaphysical Tracts, 1837), " a defence of the individuality of the human mind or self." In 1765 the first four volumes of his work were published under the pseudonym " Edward Search." The remaining three volumes appeared posthumously. His eyesight failed him completely in 1771, but he contrived an ingenious apparatus which enabled him to write so legibly that the result could easily be transcribed by his daughter. In this way he completed the later volumes, which were ready for publication when he died on the 20th of November 1774.
His work embraces in its scope many psychological and more strictly metaphysical discussions, but it is chiefly in connexion with ethics that Tucker s speculations are remembered. In some impor- tant points he anticipates the utilitarianism afterwards systematized by Paley, who expresses in the amplest terms his obligations to his predecessor. " Every man's own satisfaction " Tucker holds to be the ultimate end of action; and satisfaction or pleasure is one and the same in kind, however much it may vary in degree. This universal motive is further connected, as by Paley, through the will of God, with the " general good, the root where out all our rules of conduct and sentiments of honour are to branch."
The Light of Nature was republished with a biographical sketch by Tucker's grandson, Sir H. P. St John Mildmay (1905), 7 vols. (other editions 1834, 1836, etc.), and an abridged edition by W. Hazhtt appeared in 1807.
