Opinion, Belief or Faith, and Knowledge

Abstract

Kant famously said he 'had to deny knowledge (Wissen) in order to make room for faith (Glaube)’ (B xxx). But what exactly was his conception of Glaube, and how does it fit into his epistemology? In the first Critique it is not until the concluding Method section that he explicitly addresses these issues. In the Canon of Pure Reason he lists three questions that sum up ‘all interest of my reason’: What can I know? What should I do? What may I hope? (A 805/B 833). Kant here put hope on the agenda of philosophy. In his essays on history he argued that we can hope for secular progress in the development of human culture; but in his moral and religious philosophy he was also concerned with eschatological hopes that we can perfect our characters in a life after death, and that the moral governor of the universe will ensure that happiness is eventually proportionate to virtue. About immortality and the existence of God, his constant refrain is that we can have only a practical kind of faith (Glaube).
