Without good reason : the rationality debate in philosophy and cognitive science

Are humans rational? Various experiments performed over the last several decades have been interpreted as showing that humans are irrational; certain philosophers, on the other hand, have argued that it is a conceptual truth that humans must be rational. Without Good Reason offers a clear critical account of the rationality debate in philosophy and cognitive science, concluding that the question of human rationality is indeed an empirical one not a conceptual one.
