Not… what opinions are held, but… how they are held: instead of being held dogmatically, [liberal] opinions are held tentatively, and with a consciousness that new evidence may at any moment lead to their abandonment. – Bertrand Russell, Unpopular Essays, 1950
Hormones, vitamines, stimulants and depressives are oils upon the creaky machinery of life. Principal item, however, is the machinery. – Martin H. Fischer (1879–1962)
