Kant’s most important book is The Critique of Pure Reason, (ist edition 1781 ; 2nd edition 1787.) The purpose of this work is to prove that, although none of our knowledge can transcend experience, it is nevertheless in part a priori and not inferred inductively from experience. The part of our knowledge which is a priori embraces, according to him, not only logic, but much that cannot be included in logic or deduced from it.
