Famous quotes containing the words biological and/or matter:
“No further evidence is needed to show that “mental illness” is not the name of a biological condition whose nature awaits to be elucidated, but is the name of a concept whose purpose is to obscure the obvious.”
—Thomas Szasz (b. 1920)
“I must beg you to indulge me in the matter of hyphens.... You will find that I have marked out a great many in the proofs. We are in danger of Germanizing our printing by using them so much, and I have a very decided preference in the matter.”
—Woodrow Wilson (1856–1924)
