Famous quotes containing the word necessity:
“The sadness of the women’s movement is that they don’t allow the necessity of love. See, I don’t personally trust any revolution where love is not allowed.”
—Maya Angelou (b. 1928)
“This, indeed, has always been the fate of the few that have professed scepticism, that, when they have done what they can to discredit their senses, they find themselves, after all, under a necessity of trusting to them. Mr. Hume has been so candid as to acknowledge this; and it is no less true of those who have shewn the same candour; for I never heard that any sceptic runs his head against a post, or stepped into a kennel, because he did not believe his eyes.”
—Thomas Reid (1710–1796)
“We are sure that, though we know not how, necessity does comport with liberty, the individual with the world, my polarity with the spirit of the times. The riddle of the age has for each a private solution.”
—Ralph Waldo Emerson (1803–1882)
