If I Simply Refrain From Making A

With Me, Everything Turns Into Mathematics.

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.

I Concluded That I Might Take As A General Rule The Principle That All Things Which We Very Clearly And Obviously Conceive Are True: Only Observing, However, That There Is Some Difficulty In Rightly Determining The Objects Which We Distinctly Conceive.

And Thereby Make Ourselves, As It Were, The Lords And Masters Of Nature.

In The Matter Of A Difficult Question It Is More Likely That The Truth Should Have Been Discovered By The Few Than By The Many.
