Key passages
“As we were at one time children, and as we formed various judgments regarding the objects presented to our senses, when as yet we had not the entire use of our reason, numerous prejudices stand in the way of our arriving at the knowledge of truth; and of these it seems impossible for us to rid ourselves, unless we undertake, once in our lifetime, to doubt of all those things in which we may discover even the smallest suspicion of uncertainty.”
Because we were once children and made judgments based on sensory experience before our reason was fully developed, we are burdened with many prejudices that block truth; the only way to overcome them is to doubt everything that could possibly be uncertain, at least once in our lives.
This passage establishes the motivation and method for Descartes' radical doubt.
