Descartes method of doubt is to through out all ideas and truths that can be doubted. He would doubt everything including God's and his own existence. The first principal he tackled is sense perception, a major source of beliefs. He believed they can certainly be doubted because people are often misled by there senses

An example of Descartes method of doubt would be his doubt of senses (a major source of beliefs), an ore in the water appears bent, but in reality it is straight. He has been fooled before by a dream in which he actually thinks he is doing something or that some thing exists, but when he awakes he finds out he was misled. He gives the example of his hand in front of his face, he can doubt that because again he may be dreaming his hand.

Descartes believed that all knowledge is related and if he were to build his knowledge on solid undoubtable foundation of facts, his knowledge would be pure. Descartes is trying to prove a solid body of knowledge in which he can build more solid knowledge upon. His first undoubtable truth is that he exists (I think, therefore I am). He then attempts to build upon this to prove God and the existence of corporeal objects. Descartes believed his utility of doubt would deliver him from every kind of prejudice.

The Problems with this method is he did not doubt his own sanity, language itself or logic.
