In the philosophy of science classical rationalism equates rationality with proof and proof with Truth.
What is the meaning of rather 'critical rationalism'? Is it the view advocated by Popper by which rationality is no more than criticism as opposed to'proof'? If so, does critical rationalism give up Truth? Or does it give up certainty only? If he only gives up certainty but does not give up Truth, how does it still reach Truth?
