There is such a thing as food and such a thing as poison. But the damage done by those who pass off poison as food is far less than that done by those who generation after generation convince people that food is poison.
(Paul Goodman (1911-1972), U.S. author, poet, critic. "Ireland, Spring 1958," sct. 2, Five Years (1966).)
Virtue, like wholesome food, is better than poisons, however corrected.
(David Hume (1711-1776), Scottish philosopher. "Of Refinement in the Arts," part II, essay II, p. 279, Essays Moral, Political, and Literary, ed. Eugene F. Miller, revised edition, Indianapolis, Liberty Fund, Inc. (1987).)
