Famous quotes containing the word universal:
“The earliest instinct of the child, and the ripest experience of age, unite in affirming simplicity to be the truest and profoundest part for man. Likewise this simplicity is so universal and all-containing as a rule for human life, that the subtlest bad man, and the purest good man, as well as the profoundest wise man, do all alike present it on that side which they socially turn to the inquisitive and unscrupulous world.”
—Herman Melville (1819–1891)
“I have been maintaining that the meaning of the word ‘ought’ and other moral words is such that a person who uses them commits himself thereby to a universal rule. This is the thesis of universalizability.”
—Richard M. Hare (b. 1919)
