So Far As Physics Is Concerned, Time's

I Am Aware That Many Critics Consider The Conditions In The Stars Not Sufficiently Extreme . . . The Stars Are Not Hot Enough. The Critics Lay Themselves Open To An Obvious Retort: We Tell Them To Go And Find A Hotter Place.

Observation And Theory Get On Best When They Are Mixed Together, Both Helping One Another In The Pursuit Of Truth. It Is A Good Rule Not To Put Overmuch Confidence In A Theory Until It Has Been Confirmed By Observation. I Hope I Shall Not Shock The Experimental Physicists Too Much If I Add That It Is Also A Good Rule Not To Put Overmuch Confidence In The Observational Results That Are Put Forward Until They Have Been Confirmed By Theory.

The Helium Which We Handle Must Have Been Put Together At Some Time And Some Place. We Do Not Argue With The Critic Who Urges That The Stars Are Not Hot Enough For This Process; We Tell Him To Go And Find A Hotter Place.

It Is A Primitive Form Of Thought That Things Exist Or Do Not Exist.

Science Is One Thing, Wisdom Is Another. Science Is An Edged Tool, With Which Men Play Like Children, And Cut Their Own Fingers.
