This research is aimed at critical study of John Searle''s criticism of artificial intelligence and cognitive science. The main stance of Searle is defended against the counter arguments . However at the same time few problems with Searle''s position are explained as well. Finally it is shown that Searle''s successful refutation of cognitive science is demanding a complete cognitive science .His idea is that a genuine science of cognition should allow more than what it promises at the moment.
