I Have Spoken To Einstein And He

It Is Not Intuitive Ease I Am After, But Rather A Point Of View Which Is Sufficiently Definite To Clear Up Some Difficulties, And To Be Criticized In Rational Terms. (bohr's Complementarity Cannot Be So Criticized, I Fear; It Can Only Be Accepted Or Denounced - Perhaps As Being Ad Hoc, Or As Being Irrational, Or As Being Hopelessly Vague.)

I Have Come To The Conclusion That Darwinism Is Not A Testable Scientific Theory, But A Metaphysical Research Programme.

We Know A Great Deal, But Our Ignorance Is Sobering And Boundless. With Each Step Forward, With Each Problem Which We Solve, We Not Only Discover New And Unsolved Problems, But We Also Discover That Where We Believed That We Were Standing On Firm And Safe Ground, All Things Are, In Truth, Insecure And In A State Of Flux.

A System Is Empirical Or Scientific Only If It Is Capable Of Being Tested By Experience. These Considerations Suggest That Not The Verifiability But The Falsifiability Of A System Is To Be Taken As A Criterion Of Demarcation... It Must Be Possible For An Empirical Or Scientific System To Be Refuted By Experience.

But It Is Certainly Not Possible To Insist On One Hand That The Formalism Is Complete And To Insist On The Other Hand That Its Application To 'the Actual' Actually Demands A Step Which Cannot Be Derived From It.
