"Metaphysics therefore, both of nature and of morals, principally the critique of reason daring to fly on its own wings [...] alone define what we can call philosophy in its true understanding." Immanuel Kant Manfred Baum has particularly dedicated himself to exploring Kant's philosophy in its systematic significance. Metaphysics and critique are fundamental functions for Kant's concept of philosophy. The volume contains papers (in English and German language) by internationally acknowledged experts dealing with Kant's theoretical and practical philosophy.
