There Is No History, Only Histories.

[great Scientists] Are Men Of Bold Ideas, But Highly Critical Of Their Own Ideas: They Try To Find Whether Their Ideas Are Right By Trying First To Find Whether They Are Not Perhaps Wrong. They Work With Bold Conjectures And Severe Attempts At Refuting Their Own Conjectures.

The History Of Science, Like The History Of All Human Ideas, Is A History Of Irresponsible Dreams, Of Obstinacy, And Of Error.

Every Genuine Test Of A Theory Is An Attempt To Falsify It, Or To Refute It.

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.

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.)
