Quote by Putnam, Hilary
"The attempt to ground knowledge in certainty is bound to fail; we must accept degrees of justification."
More from Putnam, Hilary
"The world is not intrinsically divided into minds and physical objects."
"Realism is not the view that the world exists independently of all schemes of description."
"Truth is not correspondence to reality."
"We can have a rational picture of the world only if we are willing to question our intuitions."
