Idealism in Kant and Berkeley

It has become common in philosophy to see Immanuel Kant as a sophisticated proponent of a worldview that is shared by some scientists while Bishop G. Berkeley is referred to only as a slightly crazy adherent of the view that matter does not exist at all. Kant nevertheless called his theory ‘transcendental idealism’ and distinguished it from the ‘problematic idealism’ of Descartes and from the ‘dogmatic idealism’ of Berkeley. Berkeley often refers to his own system as ‘immaterialism,’ and this certainly suggests the idea that there is no material world. On the other hand, Berkeley most often claimed to be a common-sense philosopher, who would not deny things that common sense would affirm. Berkeley can say so much, even on the most simplistic interpretation, save that he claims to know that the ‘something’ is God.
