Genius, As An Explosive Power,

There Are Some Men Who Are Counted Great Because They Represent The Actuality Of Their Own Age, And Mirror It As It Is. Such An One Was Voltaire, Of Whom It Was Epigrammatically Said: "he Expressed Everybody's Thoughts Better Than Anyone." But There Are Other Men Who Attain Greatness Because They Embody The Potentiality Of Their Own Day And Magically Reflect The Future. They Express The Thoughts Which Will Be Everybody's Two Or Three Centuries After Them. Such As One Was Descartes.

Ecclesiasticism In Science Is Only Unfaithfulness To Truth

Man's Place In Nature.

As To Sagacity, I Should Say That His Judgement Respecting The Warmest Place And The Softest Cushion In A Room Is Infallible, His Punctuality At Meal Times Is Admirable, And His Pertinacity In Jumping On People's Shoulders Till They Give Him Some Of The Best Of What Is Going, Indicates Great Firmness.

It Is Not To Be Forgotten That What We Call Rational Grounds For Our Beliefs Are Often Extremely Irrational Attempts To Justify Our Instincts.
