The Percept Is The Reality. It Is Not In Propositional Form. But The Most Immediate Judgment Concerning It Is Abstract.

We Cannot Begin With Complete Doubt. We Must Begin With All The Prejudices Which We Actually Have When We Enter Upon The Study Ofphilosophy. These Prejudices Are Not To Be Dispelled By A Maxim, For They Are Things Which It Does Not Occur To Us Can Be Questioned. A Person May, It Is True, In The Course Of His Studies, Find Reason To Doubt What He Began By Believing; But In That Case He Doubts Because He Has A Positive Reason For It, And Not On Account Of The Cartesian Maxim. Let Us Not Pretend To Doubt In Philosophy What We Do Not Doubt In Our Hearts.
