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)
“There is no necessity to separate the monarch from the mob; all authority is equally bad.”
—Oscar Wilde (1854–1900)
