Neither Divine Grace Nor Natural

I Can Doubt Everything, Except One Thing, And That Is The Very Fact That I Doubt. Simply Put - I Think, Therefore I Am

I Am Indeed Amazed When I Consider How Weak My Mind Is And How Prone To Error.

You Just Keep Pushing. You Just Keep Pushing. I Made Every Mistake That Could Be Made. But I Just Kept Pushing.

I Hope That Posterity Will Judge Me Kindly, Not Only As To The Things Which I Have Explained, But Also To Those Which I Have Intentionally Omitted So As To Leave To Others The Pleasure Of Discovery.

I Did Not Imitate The Skeptics Who Doubt Only For Doubting's Sake, And Pretend To Be Always Undecided; On The Contrary, My Whole Intention Was To Arrive At A Certainty, And To Dig Away The Drift And The Sand Until I Reached The Rock Or The Clay Beneath.
