In So Far As A Scientific Statement

There Can Be No Ultimate Statements Science: There Can Be No Statements In Science Which Can Not Be Tested, And Therefore None Which Cannot In Principle Be Refuted, By Falsifying Some Of The Conclusions Which Can Be Deduced From Them.

A Rationalist, As I Use The Word, Is A Man Who Attempts To Reach Decisions By Argument And Perhaps, In Certain Cases, By Compromise, Rather Than By Violence. He Is A Man Who Would Rather Be Unsuccessful In Convincing Another Man By Argument Than Successful In Crushing Him By Force, By Intimidation And Threats, Or Even By Persuasive Propaganda.

Every Discovery Contains An Irrational Element Or A Creative Intuition.

The Old Scientific Ideal Of Episteme - Of Absolutely Certain, Demonstrable Knowledge - Has Proved To Be An Idol. The Demand For Scientific Objectivity Makes It Inevitable That Every Scientific Statement Must Remain Tentative For Ever.

If We Are Not Prepared To Defend A Tolerant Society Against The Onslaught Of The Intolerant, Then The Tolerant Will Be Destroyed, And Tolerance With Them.
