Man Is The Matter Of The Cosmos,

Books Tap The Wisdom Of Our Species -- The Greatest Minds, The Best Teachers -- From All Over The World And From All Our History. And They're Patient.

Religions Contradict One Another-on Small Matters, Such As Whether We Should Put On A Hat Or Take One Off On Entering A House Of Worship, Or Whether We Should Eat Beef And Eschew Pork Or The Other Way Around, All The Way To The Most Central Issues, Such As Whether There Are No Gods, One God, Or Many Gods.

In Science It Often Happens That Scientists Say, "you Know That's A Really Good Argument; My Position Is Mistaken..."

I Would Be Very Ashamed Of My Civilization If We Did Not Try To Find Out If There Is Life In Outer Space.

In Science It Often Happens That Scientists Say, 'you Know That's A Really Good Argument; My Position Is Mistaken,' And Then They Would Actually Change Their Minds And You Never Hear That Old View From Them Again. They Really Do It. It Doesn't Happen As Often As It Should, Because Scientists Are Human And Change Is Sometimes Painful. But It Happens Every Day. I Cannot Recall The Last Time Something Like That Happened In Politics Or Religion.
