At Last I Will Devote Myself Sincerely

Although My Knowledge Grows More And More, Nevertheless I Do Not For That Reason Believe That It Can Ever Be Actually Infinite, Since It Can Never Reach A Point So High That It Will Be Unable To Attain Any Greater Increase.

I Think; Therefore I Am.

By 'god', I Understand, A Substance Which Is Infinite, Independent, Supremely Intelligent, Supremely Powerful, And Which Created Both Myself And Everything Else [...] That Exists. All These Attributes Are Such That, The More Carefully I Concentrate On Them, The Less Possible It Seems That They Could Have Originated From Me Alone. So, From What Has Been Said It Must Be Concluded That God Necessarily Exists.

On The One Hand I Have A Clear And Distinct Idea Of Myself, In So Far As I Am A Thinking, Non-extended Thing; And On The Other Hand I Have A Distinct Idea Of Body, In So Far A This Is Simply An Extended, Non-thinking Thing. And, Accordingly, It Is Certain That I Am Really Distinct From My Body, And Exist Without It.

Let Whoever Can Do So Deceive Me, He Will Never Bring It About That I Am Nothing, So Long As I Continue To Think I Am Something.
