In Order To Improve The Mind, We

Whatever I Have Up Till Now Accepted As Most True And Assured I Have Gotten Either From The Senses Or Through The Senses. But From Time To Time I Have Found That The Senses Deceive, And It Is Prudent Never To Trust Completely Those Who Have Deceived Us Even Once.

Hence Reason Also Demands That, Since Our Thoughts Cannot All Be True Because We Are Not Wholly Perfect, What Truth They Do Possess Must Inevitably Be Found In The Thoughts We Have When Awake, Rather Than In Our Dreams.

I Should Consider That I Know Nothing About Physics If I Were Able To Explain Only How Things Might Be, And Were Unable To Demonstrate That They Could Not Be Otherwise.

It Is Contrary To Reasoning To Say That There Is A Vacuum Or Space In Which There Is Absolutely Nothing.

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