Descartes’s “rationalist” philosophy

QUESTION 1: On Hume and his Empiricism: by using your knowledge of Descartes’s “rationalist” philosophy, explain how Hume, as an empiricist, would critique Descartes’ “proof” of the existence of God.
QUESTION 2. We positioned Kant between both Hume (an empiricist) and Descartes (a rationalist). Explain how Kant’s philosophical stance rests between both; that is, what does Kant say to Hume and what does he say to Descartes? Remember to focus on the respective theories of knowledge in Hume (the empiricist. who’s concerned to ground all knowledge is only experience) and Descartes (the rationalist, who thinks that some knowledge can be known independently of any experience).
