Give Me Extension And Motion And I

Nothing Is More Fairly Distributed Than Common Sense: No One Thinks He Needs More Of It Than He Already Has.

Hence Reason Also Demands That, Since Our Thoughts Cannot All Be True Because We Are Not Wholly Perfect, What Truth They Do Possess Must Inevitably Be Found In The Thoughts We Have When Awake, Rather Than In Our Dreams.

I Am Thinking, Therefore I Exist. (...) I Was A Substance Whose Whole Essence Or Nature Is Solely To Think, And Which Does Not Require Any Place, Or Depend On Any Material Thing, In Order To Exist. Accordingly This 'i' - That Is, The Soul By Which I Am What I Am - Is Entirely Distinct From The Body, And Indeed Is Easier To Know Than The Body, And Would Not Fail To Be Whatever It Is, Even If The Body Did Not Exist.

Conquer Yourself Rather Than The World.

How Do We Know That Anything Really Exists, That Anything Is Really The Way It Seems Ot Us Through Our Senses?
