On Hempel's Paradoxes Of Confirmation

The paradoxes of confirmation were found by Hempel when hestudied Nicod's criterion of confirmation and the equivalence condition,which include intuitive paradoxes and logical paradoxes of confirmation.This discovery gives rise to scientific philosophers' extreme attention tothem. A lot of philosophers try to resolve them, though some of theirmethods are not very satisfying, these methods provide good thinking forus. Firstly, this article will introduce the method of solving theseparadoxes, which is provided by Hempel. He concludes the appearance ofparadoxes to our reliance on a misleading intuition. He thinks that theimpression of a paradoxical situation is not objectively founded and thatit is a psychological illusion. Secondly, this article will introduce themethod of solving these paradoxes, which is provided by Von Wright.He puts forward the concept of "range of relevance" in the range ofdeductive logic. Finally, this article will introduce in detail the methodwhich Howson and Urbach apply the Bayesian notion of confirmation tosolve the paradoxes of confirmation. By the contrast of the three methods,we think the Bayesian method of Howson and Urbach has a good future.
