If You Know That Things Are Bound

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.

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

Science May Be Described As The Art Of Systematic Over-simplification.

If We Are Uncritical We Shall Always Find What We Want: We Shall Look For, And Find, Confirmations, And We Shall Look Away From, And Not See, Whatever Might Be Dangerous To Our Pet Theories. In This Way It Is Only Too Easy To Obtain What Appears To Be Overwhelming Evidence In Favor Of A Theory Which, If Approached Critically, Would Have Been Refuted.

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.
