Truth, springs from agrument amongst friends. — David Hume. Scottish philosopher, historian, economist and essayist (1711–1776)
Learning has been [a] great loser by being shut up in colleges and cells and secluded from the world and good company.
If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, "Does it contain any abstract reasoning concerning quantity or number?" No. "Does it contain any experimental reasoning concerning matter of fact and existence?" No. Commit it then to the flames: for it can contain nothing but sophistry and illusion.
