We Do Not Describe The

The Senses Deceive From Time To Time, And It Is Prudent Never To Trust Wholly Those Who Have Deceived Us Even Once.

I Should Consider That I Know Nothing About Physics If I Were Able To Explain Only How Things Might Be, And Were Unable To Demonstrate That They Could Not Be Otherwise.

Be That As It May, There Is Fixed In My Mind A Certain Opinion Of Long Standing, Namely That There Exists A God Who Is Able To Do Anything And By Whom I, Such As I Am, Have Been Created. How Do I Know That He Did Not Bring It About That There Is No Earth At All, No Heavens, No Extended Thing, No Shape, No Size, No Place, And Yet Bringing It About That All These Things Appear To Me To Exist Precisely As They Do Now?

I Suppose Therefore That All Things I See Are Illusions; I Believe That Nothing Has Ever Existed Of Everything My Lying Memory Tells Me. I Think I Have No Senses. I Believe That Body, Shape, Extension, Motion, Location Are Functions. What Is There Then That Can Be Taken As True? Perhaps Only This One Thing, That Nothing At All Is Certain.

I Am Accustomed To Sleep And In My Dreams To Imagine The Same Things That Lunatics Imagine When Awake.
