ABSTRACT
We have noted the central aim of the Critical Philosophy: to set boundaries to the use of human reason. In the previous two chapters we have explored the grounds Kant offers for the contention that religious faith cannot cross over the boundaries set for knowledge in the Critical system. Religious faith is possible but it cannot in principle amount to knowledge. It is not even on the scale that includes opinion at one end and knowledge at the other. But for faith to be possible, God – and the other Ideas of Reason – must surely be thinkable.
