The Positivists Have A Simple Solution: The World Must Be Divided Into That Which We Can Say Clearly And The Rest, Which We Had Better Pass Over In Silence. But Can Anyone Conceive Of A More Pointless Philosophy, Seeing That What We Can Say Clearly Amounts To Next To Nothing? If We Omitted All That Is Unclear, We Would Probably Be Left Completely Uninteresting And Trivial Tautologies.

You May Object That By Speaking Of Simplicity And Beauty I Am Introducing Aesthetic Criteria Of Truth, And I Frankly Admit That I Am Strongly Attracted By The Simplicity And Beauty Of Mathematical Schemes Which Nature Presents Us. You Must Have Felt This Too: The Almost Frightening Simplicity And Wholeness Of The Relationship, Which Nature Suddenly Spreads Out Before Us.

Modern Physics Has Changed Nothing In The Great Classical Disciplines Of, For Instance, Mechanics, Optics, And Heat. Only The Conception Of Hitherto Unexplored Regions, Formed Prematurely From A Knowledge Of Only Certain Parts Of The World, Has Undergone A Decisive Transformation. This Conception, However, Is Always Decisive For The Future Course Of Research.

In The Strict Formulation Of The Law Of Causality—if We Know The Present, We Can Calculate The Future—it Is Not The Conclusion That Is Wrong But The Premise. On An Implication Of The Uncertainty Principle.

I Believe That The Existence Of The Classical "path" Can Be Pregnantly Formulated As Follows: The "path" Comes Into Existence Only When We Observe It.
