Famous quotes containing the words sound and/or system:
“You can’t, in sound morals, condemn a man for taking care of his own integrity. It is his clear duty. And least of all can you condemn an artist pursuing, however humbly and imperfectly, a creative aim. In that interior world where his thought and his emotions go seeking for the experience of imagined adventures, there are no policemen, no law, no pressure of circumstance or dread of opinion to keep him within bounds. Who then is going to say Nay to his temptations if not his conscience?”
—Joseph Conrad (1857–1924)
“Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.”
—Rudolf Carnap (1891–1970)
