Errors Are Not In The Art But

The Best Way To Understanding Is A Few Good Examples.

A Vulgar Mechanick Can Practice What He Has Been Taught Or Seen Done, But If He Is In An Error He Knows Not How To Find It Out And Correct It, And If You Put Him Out Of His Road He Is At A Stand. Whereas He That Is Able To Reason Nimbly And Judiciously About Figure, Force, And Motion, Is Never At Rest Till He Gets Over Every Rub. (from A Letter Dated 25 May, 1694)

He Who Thinks Half-heartedly Will Not Believe In God; But He Who Really Thinks Has To Believe In God.

To Derive Two Or Three General Principles Of Motion From Phænomena, And Afterwards To Tell Us How The Properties And Actions Of All Corporeal Things Follow From Those Manifest Principles, Would Be A Very Great Step In Philosophy.

I See I Have Made My Self A Slave To Philosophy.
