If You Would Be A Real Seeker

When I Consider This Carefully, I Find Not A Single Property Which With Certainty Separates The Waking State From The Dream. How Can You Be Certain That Your Whole Life Is Not A Dream?

I Accept No Principles Of Physics Which Are Not Also Accepted In Mathematics.

Common Sense Is The Most Fairly Distributed Thing In The World, For Each One Thinks He Is So Well-endowed With It That Even Those Who Are Hardest To Satisfy In All Other Matters Are Not In The Habit Of Desiring More Of It Than They Already Have.

It Is Possible That I Am Dreaming Right Now And That All Of My Perceptions Are False.

As I Considered The Matter Carefully It Gradually Came To Light That All Those Matters Only Were Referred To Mathematics In Which Order And Measurements Are Investigated, And That It Makes No Difference Whether It Be In Numbers, Figures, Stars, Sounds Or Any Other Object That The Question Of Measurement Arises. I Saw Consequently That There Must Be Some General Science To Explain That Element As A Whole Which Gives Rise To Problems About Order And Measurement, Restricted As These Are To No Special Subject Matter. This, I Perceived Was Called 'universal Mathematics'.
