The Importance of Religion for Kant´s Moral. A Investigation of the development

This Work pretends to examinate the relation between Kant´s moral und religions philosophy. That´s why the main text in this investigation are those about moral: 'Grundlegung zur Metaphysik der Sitten' (1785), 'Kritik der praktischen Vernunft' (1787) and the 'Vorlesungen' and 'Reflexionen zur Moralphilosophie'. An important place too have the 'Kritik der reinen Vernunft' (1781 und 1787) and the 'Religion innerhalb der Grenzen der bloßen Vernunft' (1791). Related to this texts we make the question about the meaning of the religion in the moral philosophy of Kant. Because this meaning ist different in the 'Vorlesungen' and in the 'Reflexionen' as in Kant´s moral Works we analyse they separatly to demonstrate that this difference its enougt to confirm that Kant´s moral philosophy hat two periods in relation with the meaning of religion
