Comparing Knowledge in Descartes’ Meditations on First Philosophy and Hume’s An Enquiry Concerning Human Understanding,

Rationalists would claim that knowledge comes from reason or ideas, while empiricists would answer that knowledge is derived from the senses or impressions. The difference between these two philosophical schools of thought, with respect to the distinction between ideas and impressions, can be examined in order to determine how these schools determine the source of knowledge. The distinguishing factor that determines the perspective on the foundation of knowledge is the concept of the divine.

Descartes is a prime example of a rationalist. Descartes begins his Meditations on First Philosophy by doubting his senses in the first meditation. “From time to time I [Descartes] have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once”(Descartes: 12). In the second meditation, Descartes begins to rebuild the world he broke down in the first meditation by establishing cogito ergo sum with the aid of natural light.

The presence of a concept of the divine is the deciding factor of whether knowledge originates from the senses or the ideas.
