The Attempt To Make Heaven On Earth

I Think That We Shall Have To Get Accustomed To The Idea That We Must Not Look Upon Science As A 'body Of Knowledge,' But Rather As A System Of Hypotheses; That Is To Say, As A System Of Guesses Or Anticipations Which In Principle Cannot Be Justified, But With Which We Work As Long As They Stand Up To Tests, And Of Which We Are Never Justified In Saying That We Know They Are 'true' Or 'more Or Less Certain' Or Even 'probable.'

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.)

Our Belief In Any Particular Natural Law Cannot Have A Safer Basis Than Our Unsuccessful Critical Attempts To Refute It.

Plato Felt That A Complete Reconstruction Of Society's Political Program Was Needed.

Better Our Hypotheses Die For Our Errors Than Ourselves.
