Descartes’ Philosophy: Substance, Doubt, and Existence
Descartes’ Philosophy: Doubt and the Foundations of Knowledge
After applying metaphysical doubt, as required by his method, Descartes concludes that there is one thing he cannot doubt: that he is doubting.

Knowledge
The generalization, as a process to convert observable facts into laws or principles, is carried out by inference (connected to understanding). There are two types of inference:
- Deductive: Passage from one concept to another (cause-effect relationships).
