You Can't Have It Both

I Have Great Faith In Optimism As A Guiding Principle, If Only Because It Offers Us The Opportunity Of Creating A Self-fulfilling Prophecy.

A Single Test Which Proves Some Piece Of Theory Wrong Is More Valuable Than A Hundred Tests Showing That Idea Might Be True.

Every Age Has Its Dreams, Its Symbols Of Romance. Past Generations Were Moved By The Graceful Power Of The Great Windjammers, By The Distant Whistle Of Locomotives Pounding Through The Night, By The Caravans Leaving On The Golden Road To Samarkand, By Quinqueremes Of Nineveh From Distant Ophir . . . Our Grandchildren Will Likewise Have Their Inspiration-among The Equatorial Stars. They Will Be Able To Look Up At The Night Sky And Watch The Stately Procession Of The Ports Of Earth-the Strange New Harbors Where The Ships Of Space Make Their Planetfalls And Their Departures.

A Faith That Cannot Survive Collision With The Truth Is Not Worth Many Regrets.

In Fact, One Of The Arguments For Searching For Intelligent Life In Space, Elsewhere, Is That We Have No Evidence That Intelligence Has Any Survival Value. The Most Successful Creatures On This Planet Are The Cockroaches. They've Been Around, What Is It, 100 Million Years Or So And I Suspect They'll Still Be There 100 Million Years In The Future. Maybe Intelligence Is An Evolutionary Aberration Which Dooms Its Possessors In The Way Armor May Have Doomed Some Of The Dinosaurs.
