What is certainty for Descartes?
According to this conception, epistemic certainty requires an infallible guarantee that is (reflexively) accessible to the subject (Dutant 2015).

In the Third Meditation, Descartes says that he is certain that he is a thinking thing, and he explains the certainty of this “first item of knowledge” (it is unclear whether he regards it as distinct from the cogito) as resulting from the fact that it is a clear and distinct perception (PW 2, p. 24).
What is the cause of error according to Descartes?
Errors arises because of the fact that while our understanding is finite, our will is infinite. That is, we can freely choose to believe certain things to be true even when we lack sufficient evidence. This is the core of Descartes’ analysis of errors of judgment.
How does Descartes prove that God is not a deceiver?
Thus, by Descartes’ reasoning, God cannot be a deceiver since he is supremely real and does not participate in any way in nothingness. People, on the other hand, are understood by Descartes to have finite being, and that their lack of infinite being implies that they also participate in nothingness.
What did Descartes find it impossible to doubt?
From here Descartes sets out to find something that lies beyond all doubt. He eventually discovers that “I exist” is impossible to doubt and is, therefore, absolutely certain.
Why does Descartes think we can doubt even math and logic?
ABSTRACT: The view that Descartes called mathematical propositions into doubt as he impugned all beliefs concerning common-sense ontology by assuming that all beliefs derive from perception seems to rest on the presupposition that the Cartesian problem of doubt concerning mathematics is an instance of the problem of …
