God and Religion of the Enlightened Man According to Kant

Having revealed an illusion of man’s cognitive efforts, Kant sealed the progress of enlightenment inscribed into a historical process, with a deep conviction that an ancient Greek prescription to “know thyself” was finally fulfilled. A man became aware of being equipped with a mind, and accordingly, with freedom as well as the ability to act morally, still remaining a finite natural being with limited cognitive skills. This critical self-knowledge of an enlightened man relieved him of his nonage to open his eyes for a new vision of both the world and a man himself regarded as a self-conscious subject and active creator of his fate.

The character and ontological status of religious beliefs, the enlightened man confesses, are in fact defined by the famous Kantian formula: as if (als ob). Driven by moral reasons, they are distinguished with a rationality for which a fundamental value is the Highest Good, purely rationalistic construction, a kind of God thought to be an essential being and a ration for existence of the phenomenal world.
