Doubt Is The Origin Of Wisdom

Even If I Were To Suppose That I Was Dreaming And Whatever I Saw Or Imagined Was False, Yet I Could Not Deny That Ideas Were Truly In My Mind.

Desire Awakens Only To Things That Are Thought Possible.

Wonder Is The First Of All The Passions.

For I Found Myself Embarrassed With So Many Doubts And Errors That It Seemed To Me That The Effort To Instruct Myself Had No Effect Other Than Th Eincreasing Discovery Of My Own Ignorance

The Only Secure Knowledge Is That I Exist.
