Science May Be Described As The Art

It Is Clear That Everybody Interested In Science Must Be Interested In World 3 Objects. A Physical Scientist, To Start With, May Be Interested Mainly In World 1 Objects--say Crystals And X-rays. But Very Soon He Must Realize How Much Depends On Our Interpretation Of The Facts, That Is, On Our Theories, And So On World 3 Objects. Similarly, A Historian Of Science, Or A Philosopher Interested In Science Must Be Largely A Student Of World 3 Objects.

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.'

The Survival Value Of Intelligence Is That It Allows Us To Extinct A Bad Idea, Before The Idea Extincts Us.

The History Of Science Is Everywhere Speculative. It Is A Marvelous Hiatory. It Makes You Proud To Be A Human Being.

It Is Part Of My Thesis That All Our Knowledge Grows Only Through The Correcting Of Our Mistakes.
