If We Are Not Prepared To Defend

The Only Way To Test A Hypothesis Is To Look For All The Information That Disagrees With It.

I Do Not Overlook The Fact That There Are Irrationalists Who Love Mankind, And That Not All Forms Of Irrationalism Engender Criminality. But I Hold That He Who Teaches That Not Reason But Love Should Rule Opens Up The Way For Those Who Rule By Hate. (socrates, I Believe, Saw Something Of This When He Suggested That Mistrust Or Hatred Of Argument Is Related To Mistrust Or Hatred Of Man).

I Have Learned More From Hayek Than From Any Other Living Thinker, Except Perhaps Alfred Tarski - But Not Even Excepting Russell.

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.

Philosophy Is A Necessary Activity Because We, All Of Us, Take A Great Number Of Things For Granted, And Many Of These Assumptions Are Of A Philosophical Character; We Act On Them In Private Life, In Politics, In Our Work, And In Every Other Sphere Of Our Lives -- But While Some Of These Assumptions Are No Doubt True, It Is Likely, That More Are False And Some Are Harmful. So The Critical Examination Of Our Presuppositions -- Which Is A Philosophical Activity -- Is Morally As Well As Intellectually Important.
