We Have The Right Not To Tolerate

A Theory Which Is Not Refutable By Any Conceivable Event Is Non-scientific. Irrefutability Is Not A Virtue Of A Theory (as People Often Think) But A Vice.

In Point Of Fact, No Conclusive Disproof Of A Theory Can Ever Be Produced; For It Is Always Possible To Say That The Experimental Results Are Not Reliable Or That The Discrepancies Which Are Asserted To Exist Between The Experimental Results And The Theory Are Only Apparent And That They Will Disappear With The Advance Of Our Understanding. If You Insist On Strict Proof (or Strict Disproof) In The Empirical Sciences, You Will Never Benefit From Experience, And Never Learn From It How Wrong You Are.

The Quest For Precision Is Analogous To The Quest For Certainty And Both - Precision And Certainty Are Impossible To Attain.

Propose Theories Which Can Be Criticized. Think About Possible Decisive Falsifying Experiments-crucial Experiments. But Do Not Give Up Your Theories Too Easily-not, At Any Rate, Before You Have Critically Examined Your Criticism.

We All Remember How Many Religious Wars Were Fought For A Religion Of Love And Gentleness; How Many Bodies Were Burned Alive With The Genuinely Kind Intention Of Saving Souls From The Eternal Fire Of Hell.
