Every Solution Of A Problem

The Growth Of Our Knowledge Is The Result Of A Process Closely Resembling What Darwin Called 'natural Selection'; That Is, The Natural Selection Of Hypotheses: Our Knowledge Consists, At Every Moment, Of Those Hypotheses Which Have Shown Their (comparative) Fitness By Surviving So Far In Their Struggle For Existence, A Competitive Struggle Which Eliminates Those Hypotheses Which Are Unfit.

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.)

Appealing To His [einstein's] Way Of Expressing Himself In Theological Terms, I Said: If God Had Wanted To Put Everything Into The Universe From The Beginning, He Would Have Created A Universe Without Change, Without Organisms And Evolution, And Without Man And Man's Experience Of Change. But He Seems To Have Thought That A Live Universe With Events Unexpected Even By Himself Would Be More Interesting Than A Dead One.

The True Enlightenment Thinker, The True Rationalist, Never Wants To Talk Anyone Into Anything. No, He Does Not Even Want To Convince; All The Time He Is Aware That He May Be Wrong. Above All, He Values The Intellectual Independence Of Others Too Highly To Want To Convince Them In Important Matters. He Would Much Rather Invite Contradiction, Preferably In The Form Of Rational And Disciplined Criticism. He Seeks Not To Convince But To Arouse - To Challenge Others To Form Free Opinions.

It Is Impossible To Speak In Such A Way That You Cannot Be Misunderstood.
