DESCARTES' METHOD OF DOUBT
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.
