What leaded Descartes to this great problem; well before he came up with the problem he had a great education and a great opportunity to get one. I think Descartes is a man of the Lord, he understand great things that no one else can. During his studies of philosophy, he became really skeptic and starting to doubt the things he learned in the past. He studied up on Plato and his Forms and form and the natural and unnatural world.
