The Book Of Nature Is Written In

Mathematics Is The Language With Which God Has Written The Universe.

I Think That In The Discussion Of Natural Problems We Ought To Begin Not With The Scriptures, But With Experiments, And Demonstrations.

I Have Been Judged Vehemently Suspect Of Heresy, That Is, Of Having Held And Believed That The Sun In The Centre Of The Universe And Immoveable, And That The Earth Is Not At The Center Of Same, And That It Does Move. Wishing However, To Remove From The Minds Of Your Eminences And All Faithful Christians This Vehement Suspicion Reasonably Conceived Against Me, I Abjure With A Sincere Heart And Unfeigned Faith, I Curse And Detest The Said Errors And Heresies, And Generally All And Every Error, Heresy, And Sect Contrary To The Holy Catholic Church. (quoted In Shea And Artigas 194)

And Believe Me, If I Were Again Beginning My Studies, I Should Follow The Advice Of Plato And Start With The Mathematical Sciences, Which Proceed Very Cautiously And Admit Nothing As Established Until It Has Been Rigorously Demonstrated.

I Do Not Feel Obliged To Believe That The Same God Who Has Endowed Us With Senses, Reason, And Intellect Has Intended Us To Forego Their Use.
