There Is Nothing So Strange And So

Science Is Practical Philosophy.

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

For I Found Myself Embarrassed With So Many Doubts And Errors That It Seemed To Me That The Effort To Instruct Myself Had No Effect Other Than Th Eincreasing Discovery Of My Own Ignorance

My Third Maxim Was To Try Always To Conquer Myself Rather Than Fortune, And To Change My Desires Rather Than The Order Of The World, And Generally To Accustom Myself To Believing That There Is Nothing Entirely In Our Power Except Our Thoughts, So That After We Have Done Our Best Regarding Things External To Us, Everything In Which We Do Not Succeed Is For Us Absolutely Impossible.

So Blind Is The Curiosity By Which Mortals Are Possessed, That They Often Conduct Their Minds Along Unexplored Routes, Having No Reason To Hope For Success, But Merely Being Willing To Risk The Experiment Of Finding Whether The Truth They Seek Lies There.
