"I am a thinking thing, a substance whose whole essence or nature consists in thinking, and there is no need of any place, nor does it depend on any material thing."
"I have always taken the greatest pleasure in mathematics."
"My purpose is not to teach a method which everyone ought to follow to guide his reason, but only to show how I have tried to guide mine."
