Unlimited Tolerance Must Lead To The Disappearance Of Tolerance.

We Should Therefore Claim, In The Name Of Tolerance, The Right Not To Tolerate The Intolerant.

The Conspiracy Theory Of Society... Comes From Abandoning God And Then Asking: "who Is In His Place"

It Is Easy To Obtain Confirmations, Or Verifications, For Nearly Every Theory-if We Look For Confirmations. Confirmations Should Count Only If They Are The Result Of Risky Predictions... 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. Every Genuine Test Of A Theory Is An Attempt To Falsify It, Or Refute It.

Optimism Is A Duty. The Future Is Open. It Is Not Predetermined. No One Can Predict It, Except By Chance. We All Contribute To Determining It By What We Do. We Are All Equally Responsible For Its Success.

The Growth Of Our Knowledge Is The Result Of A Process Closely Resembling What Darwin Called 'natural Selection'; That Is, The Natural Selection Of Hypotheses: Our Knowledge Consists, At Every Moment, Of Those Hypotheses Which Have Shown Their (comparative) Fitness By Surviving So Far In Their Struggle For Existence, A Competitive Struggle Which Eliminates Those Hypotheses Which Are Unfit.
