Kant’s Division of Philosophy | Instant Homework Help

Except for logic, both physics and ethics, according to Kant’s division of philosophy, have an “empirical” part, in addition to a “non-empirical” or “a priori” part. (The Latin expression ‘a priori’ in philosophy means “coming prior to, and standing before all experience of the world—experience itself being made possible by the use of the various senses.”) Why, according to Kant’s way of thinking, is there a need for a “pure ethics”—that is, one that is grounded in purely a priori principles? Why can’t ethics concern itself only with what is strictly “empirical”?
