The Greatest Of The Changes That Science

There Must Be No Barriers To Freedom Of Inquiry... There Is No Place For Dogma In Science. The Scientist Is Free, And Must Be Free To Ask Any Question, To Doubt Any Assertion, To Seek For Any Evidence, To Correct Any Errors. Our Political Life Is Also Predicated On Openness. We Know That The Only Way To Avoid Error Is To Detect It And That The Only Way To Detect It Is To Be Free To Inquire. And We Know That As Long As Men Are Free To Ask What They Must, Free To Say What They Think, Free To Think What They Will, Freedom Can Never Be Lost, And Science Can Never Regress.

The Optimist Thinks This Is The Best Of All Possible Worlds. The Pessimist Fears It Is True.

Sometimes The Answer To Fear Does Not Lie In Trying To Explain Away The Causes, Sometimes The Answer Lies In Courage.

When You See Something That Is Technically Sweet, You Go Ahead And Do It And You Argue About What To Do About It Only After You Have Had Your Technical Success. That Is The Way It Was With The Atomic Bomb.

Today, It Is Not Only That Our Kings Do Not Know Mathematics, But Our Philosophers Do Not Know Mathematics And - To Go A Step Further - Our Mathematicians Do Not Know Mathematics.
