Famous quotes containing the word necessity:
“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)
“Teach thy necessity to reason thus:
There is no virtue like necessity.”
—William Shakespeare (1564–1616)
“It is the hour when stink and sweat
Subside to let the flesh forget
Affinity for brick and lathe,
The cold necessity to bathe
And certain things one would forget.”
—Allen Tate (1899–1979)
