Physics Is Much Too Hard For Physicists.

Besides It Is An Error To Believe That Rigour Is The Enemy Of Simplicity. On The Contrary We Find It Confirmed By Numerous Examples That The Rigorous Method Is At The Same Time The Simpler And The More Easily Comprehended. The Very Effort For Rigor Forces Us To Find Out Simpler Methods Of Proof.

He Who Seeks For Methods Without Having A Definite Problem In Mind Seeks In The Most Part In Vain.

Mathematics Is A Presuppositionless Science. To Found It I Do Not Need God, As Does Kronecker, Or The Assumption Of A Special Faculty Of Our Understanding Attuned To The Principle Of Mathematical Induction, As Does Poincaré, Or The Primal Intuition Of Brouwer, Or, Finally, As Do Russell And Whitehead, Axioms Of Infinity, Reducibility, Or Completeness, Which In Fact Are Actual, Contentual Assumptions That Cannot Be Compensated For By Consistency Proofs.

I Have Tried To Avoid Long Numerical Computations, Thereby Following Riemann's Postulate That Proofs Should Be Given Through Ideas And Not Voluminous Computations.

We Ought Not To Believe Those Who Today, Adopting A Philosophical Air And With A Tone Of Superiority, Prophesy The Decline Of Culter And Are Content With The Unknowable In A Self-satisfied Way. For Us There Is No Unknowable, And In My Opinion There Is Also Non Whatsoever For The Natural Sciences. In Place Of This Foolish Unknowable, Let Our Watchword On The Contrary Be: We Must Know - We Shall Know.
