Science Is Much More Than A Body Of Knowledge. It Is A Way Of Thinking. This Is Central To Its Success. Science Invites Us To Let The Facts In, Even When They Don't Conform To Our Preconceptions. It Counsels Us To Carry Alternative Hypotheses In Our Heads And See Which Ones Best Match The Facts. It Urges On Us A Fine Balance Between No-holds-barred Openness To New Ideas, However Heretical, And The Most Rigorous Skeptical Scrutiny Of Everything - New Ideas And Established Wisdom.

My Parents Were Not Scientists. They Knew Almost Nothing About Science. But In Introducing Me Simultaneously To Skepticism And To Wonder, They Taught Me The Two Uneasily Cohabiting Modes Of Thought That Are Central To The Scientific Method.

What Is Called For Is An Exquisite Balance Between Two Conflicting Needs: The Most Skeptical Scrutiny Of All Hypotheses That Are Served Up To Us And At The Same Time A Great Openness To New Ideas. If You Are Only Skeptical, Then No New Ideas Make It Through To You. On The Other Hand, If You Are Open To The Point Of Gullibility And Have Not An Ounce Of Skeptical Sense In You, Then You Cannot Distinguish Useful Ideas From The Worthless Ones.

All Of The Books In The World Contain No More Information Than Is Broadcast As Video In A Single Large American City In A Single Year. Not All Bits Have Equal Value.

One Of The Reasons For Its Success Is That Science Has A Built-in, Error-correcting Machinery At Its Very Heart. Some May Consider This An Overbroad Characterization, But To Me Every Time We Exercise Self-criticism, Every Time We Test Our Ideas Against The Outside World, We Are Doing Science. When We Are Self-indulgent And Uncritical, When We Confuse Hopes And Facts, We Slide Into Pseudoscience And Superstition.
