The Word Reality Frightens Me.

Proof Is An Idol Before Which The Mathematician Tortures Himself.

Schrödinger's Wave-mechanics Is Not A Physical Theory, But A Dodge - And A Very Good Dodge Too.

If Someone Points Out To You That Your Pet Theory Of The Universe Is In Disagreement With Maxwell's Equations - Then So Much The Worse For Maxwell's Equations. If It Is Found To Be Contradicted By Observation - Well, These Experimentalists Do Bungle Things Sometimes. But If Your Theory Is Found To Be Against The Second Law Of Thermodynamics I Can Give You No Hope; There Is Nothing For It But To Collapse In Deepest Humiliation.

Life Would Be Stunted And Narrow If We Could Feel No Significance In The World Around Us Beyond That Which Can Be Weighed And Measured With The Tools Of The Physicist Or Described By The Metrical Symbols Of The Mathematician.

Who Will Observe The Observers?
