“ 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 important points he anticipates the utilitarianism afterwards systematized by Paley, who expresses in the amplest terms his obligations to his predecessor.

“ 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. ”

“ 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. ”
