There Is No History, Only Histories.

But Some Of These Theories Are So Bold That They Can Clash With Reality: They Are The Testable Theories Of Science. And When They Clash, Then We Know That There Is A Reality; Something That Can Inform Us That Our Ideas Are Mistaken.

Do Not Allow Your Dreams Of A Beautiful World To Lure You Away From The Claims Of Men Who Suffer Here And Now. Our Fellow Men Have A Claim To Our Help; No Generation Must Be Sacrificed For The Sake Of Future Generations.

Science Must Begin With Myths, And With The Criticism Of Myths.

Science Does Not Rest Upon Solid Bedrock. The Bold Structure Of Its Theories Rises, As It Were, Above A Swamp. It Is Like A Building Erected On Piles. The Piles Are Driven Down From Above Into The Swamp, But Not Down To Any Natural Or 'given' Base; And If We Stop Driving The Piles Deeper, It Is Not Because We Have Reached Firm Ground. We Simply Stop When We Are Satisfied That The Piles Are Firm Enough To Carry The Structure, At Least For The Time Being.

The Survival Value Of Intelligence Is That It Allows Us To Extinct A Bad Idea, Before The Idea Extincts Us.
