Question

What is the Cartesian circle, and why is it a problem for Descartes's project in the Meditations?

Answer 1

The Cartesian circle is a potential mistake in reasoning associated with Rene Descartes. Descartes argues that clear and distinct perception is a guarantor of truth because God, who is not a deceiver, would not allow him to be mistaken about which he clearly and distinctly realize. The argument relies on his earlier proof of the existence of God. But he is not sure that his proof does not contain any error. He wanted to address this issue through his method of doubt. His basic strategy was to consider false any belief that falls prey to even the slightest doubt. This serves the way for what Descartes considers to be an unprejudiced search for truth.
