To Test A Perfect Theory With Imperfect

Before Another Century Is Done It Will Be Hard For People To Imagine A Time When Humanity Was Confined To One World, And It Will Seem To Them Incredible That There Was Ever Anybody Who Doubted The Value Of Space And Wanted To Turn His Or Her Back On The Universe.

Humanity Is Cutting Down Its Forests, Apparently Oblivious To The Fact That We May Not Be Able To Live Without Them.

A Good Question Is, Of Course, The Key By Which Infinite Answers Can Be Educed.

Once, When A Religionist Denounced Me In Unmeasured Terms, I Sent Him A Card Saying, "i Am Sure You Believe That I Will Go To Hell When I Die, And That Once There I Will Suffer All The Pains And Tortures The Sadistic Ingenuity Of Your Deity Can Devise And That This Torture Will Continue Forever. Isn't That Enough For You? Do You Have To Call Me Bad Names In Addition?"

Grip The Nettle Firmly And It Will Become A Stick With Which To Beat Your Enemy.
