Die Religion innerhalb der Grenzen der bloßen Vernunft

In this work, Kant delves into the relationship between religion and morality, arguing that a moral framework exists independently of religious belief and relies solely on reason.

He critiques traditional theological doctrines and discusses the concept of a supreme moral good and its implications for the existence of a divine being.

The book also presents a theory of 'radical evil' in human nature and touches on issues such as divine grace and scriptural interpretation.
