It Is Impossible To Speak In Such

No Book Can Ever Be Finished. While Working On It We Learn Just Enough To Find It Immature The Moment We Turn Away From It

If We Are Uncritical We Shall Always Find What We Want: We Shall Look For, And Find, Confirmations, And We Shall Look Away From, And Not See, Whatever Might Be Dangerous To Our Pet Theories. In This Way It Is Only Too Easy To Obtain What Appears To Be Overwhelming Evidence In Favor Of A Theory Which, If Approached Critically, Would Have Been Refuted.

If You Know That Things Are Bound To Happen Whatever You Do, Then You May Feel Free To Give Up The Fight Against Them.

There Is An Almost Universal Tendency, Perhaps An Inborn Tendency, To Suspect The Good Faith Of A Man Who Holds Opinions That Differ From Our Own Opinions. It Obviously Endangers The Freedom And The Objectivity Of Our Discussion If We Attack A Person Instead Of Attacking An Opinion Or, More Precisely, A Theory.

Thus Science Must Begin With Myths, And With The Criticism Of Myths; Neither With The Collection Of Observations, Nor With The Invention Of Experiments, But With The Critical Discussion Of Myths, And Of Magical Techniques And Practices.
