Instead Of Encouraging The Student To Devote

The Method Of Science Depends On Our Attempts To Describe The World With Simple Theories: Theories That Are Complex May Become Untestable, Even If They Happen To Be True. Science May Be Described As The Art Of Systematic Over-simplification-the Art Of Discerning What We May With Advantage Omit.

For Myself, I Am Interested In Science And In Philosophy Only Because I Want To Learn Something About The Riddle Of The World In Which We Live, And The Riddle Of Man's Knowledge Of That World. And I Believe That Only A Revival Of Interest In These Riddles Can Save The Sciences And Philosophy From An Obscurantist Faith In The Expert's Special Skill And In His Personal Knowledge And Authority.

Our Aim Must Be To Make Our Successive Mistakes As Quickly As Possible. To Speed Up Evolution.

It Must Be Possible For An Empirical Or Scientific System To Be Refuted By Experience.
