[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.

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.)

The Initial Stage, The Act Of Conceiving Or Inventing A Theory, Seems To Me Neither To Call For Logical Analysis Nor To Be Susceptible Of It.

Every Discovery Contains An Irrational Element Or A Creative Intuition.

[the Aim Of Science Is] To Explain What So Far Has Taken To Be An Explicans, Such As A Law Of Nature. The Task Of Empirical Science Constantly Renews Itself. We May Go On Forever, Proceeding To Explanations Of A Higher And Higher Universality.
