The Survival Value Of Intelligence Is That

What Really Makes Science Grow Is New Ideas, Including False Ideas.

A Theory That Explains Everything, Explains Nothing

It Is Not His Possession Of Knowledge, Of Irrefutable Truth, That Makes The Man Of Science, But His Persistent And Recklessly Critical Quest For Truth.

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.

Better Our Hypotheses Die For Our Errors Than Ourselves.
