What was one of Descartes' philosophical writings?
Descartes arrives at only a single principle: thought exists.
Thought cannot be separated from me, therefore, I exist.
Did this theory become popular?

How did he arrive at this conclusion?
Descartes concludes that he can be certain that he exists because he thinks.
But in what form?
He perceives his body through the use of the senses.

Question: Does he explain how the senses connect to thought?
