In The Way That Scepticism Is Sometimes Applied To Issues Of Public Concern, There Is A Tendency To Belittle, To Condescend, To Ignore The Fact That, Deluded Or Not, Supporters Of Superstition And Pseudoscience Are Human Beings With Real Feelings, Who, Like The Sceptics, Are Trying To Figure Out How The World Works And What Our Role In It Might Be. Their Motives Are In Many Cases Consonant With Science. If Their Culture Has Not Given Them All The Tools They Need To Pursue This Great Quest, Let Us Temper Our Criticism With Kindness. None Of Us Comes Fully Equipped.

We Are Star Stuff Harvesting Sunlight.

We Seem, These Days, Much More Willing To Recognize The Perils Before Us Than We Were Even A Decade Ago. The Newly Recognized Dangers Threaten All Of Us, Equally. No One Can Say How It Will Turn Out Down Here. But This Is Also, We May Note, The First Time That A Species Has Become Able To Journey To The Planets And The Stars.

The Absence Of Evidence Is Not The Evidence Of Absence.

The Uniqueness Of Humans Has Been Claimed On Many Grounds, But Most Often Because Of Our Tool-making, Culture, Language, Reason And Morality. We Have Them, The Other Animals Don't, And -- So The Argument Goes -- That's That.

Science Arouses A Soaring Sense Of Wonder. But So Does Pseudoscience. Sparse And Poor Popularizations Of Science Abandon Ecological Niches That Pseudoscience Promptly Fills. If It Were Widely Understood That Claims To Knowledge Require Adequate Evidence Before They Can Be Accepted, There Would Be No Room For Pseudoscience.

Science Is A Way Of Thinking Much More Than It Is A Body Of Knowledge. Its Goal Is To Find Out How The World Works, To Seek What Regularities There May Be, To Penetrate To The Connections Of Things-from Subatomic Particles, Which May Be The Constituents Of All Matter, To Living Organisms, The Human Social Community, And Thence To The Cosmos As A Whole.

Scientists Can Routinely Predict A Solar Eclipse, To The Minute, A Millennium In Advance.

If We Can't Think For Ourselves, If We're Unwilling To Question Authority, Then We're Just Putty In The Hands Of Those In Power. But If The Citizens Are Educated And Form Their Own Opinions, Then Those In Power Work For Us. In Every Country, We Should Be Teaching Our Children The Scientific Method And The Reasons For A Bill Of Rights. With It Comes A Certain Decency, Humility And Community Spirit. In The Demon-haunted World That We Inhabit By Virtue Of Being Human, This May Be All That Stands Between Us And The Enveloping Darkness.

It Is All A Matter Of Time Scale. An Event That Would Be Unthinkable In A Hundred Years May Be Inevitable In A Hundred Million.

The Dumbing Down Of American Is Most Evident In The Slow Decay Of Substantive Content In The Enormously Influential Media, The 30 Second Sound Bites (now Down To 10 Seconds Or Less), Lowest Common Denominator Programming, Credulous Presentations On Pseudoscience And Superstition, But Especially A Kind Of Celebration Of Ignorance.

When You Realize That No One Really Knows What They Are Doing And That Everyone Is Doing The Best They Can According To Their Own Level Of Consciousness, Life Gets A Lot Easier.

If We Could Travel Into The Past, It's Mind-boggling What Would Be Possible. For One Thing, History Would Become An Experimental Science, Which It Certainly Isn't Today. The Possible Insights Into Our Own Past And Nature And Origins Would Be Dazzling. For Another, We Would Be Facing The Deep Paradoxes Of Interfering With The Scheme Of Causality That Has Led To Our Own Time And Ourselves. I Have No Idea Whether It's Possible, But It's Certainly Worth Exploring.

I Am Often Amazed At How Much More Capability And Enthusiasm For Science There Is Among Elementary School Youngsters Than Among College Students.

Eratosthenes's Only Tools Were Sticks, Eyes, Feet, And Brains; Plus A Zest For Experiment. With Those Tools He Correctly Deduced The Circumference Of The Earth, To High Precision, With An Error Of Only A Few Percent. That's Pretty Good Figuring For 2200 Years Ago.

The Impediment To Scientific Thinking Is Not, I Think, The Difficulty Of The Subject. Complex Intellectual Feats Have Been Mainstays Even Of Oppressed Cultures. Shamans, Magicians And Theologians Are Highly Skilled In Their Intricate And Arcane Arts. No, The Impediment Is Political And Hierarchical.

The Cosmos Is Within Us. We Are Made Of Star Stuff

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.

The Visions We Offer Our Children Shape The Future. It _matters_ What Those Visions Are. Often They Become Self-fulfilling Prophecies. Dreams Are Maps.

At A Few Hundred Kilometers Altitude, The Earth Fills Half Your Sky, And The Band Of Blue That Stretches From Mindanao To Bombay, Which Your Eye Encompasses In A Single Glance, Can Break Your Heart With Its Beauty.

Ask Courageous Questions. Do Not Be Satisfied With Superficial Answers.

Who Are We, If Not Measured By Our Impact On Others?

In College, In The Early 1950s, I Began To Learn A Little About How Science Works, The Secrets Of Its Great Success, How Rigorous The Standards Of Evidence Must Be If We Are Really To Know Something Is True, How Many False Starts And Dead Ends Have Plagued Human Thinking, How Our Biases Can Colour Our Interpretation Of Evidence, And How Often Belief Systems Widely Held And Supported By The Political, Religious And Academic Hierarchies Turn Out To Be Not Just Slightly In Error, But Grotesquely Wrong.

Humans — Who Enslave, Castrate, Experiment On, And Fillet Other Animals — Have Had An Understandable Penchant For Pretending Animals Do Not Feel Pain. A Sharp Distinction Between Humans And 'animals' Is Essential If We Are To Bend Them To Our Will, Make Them Work For Us, Wear Them, Eat Them — Without Any Disquieting Tinges Of Guilt Or Regret. It Is Unseemly Of Us, Who Often Behave So Unfeelingly Toward Other Animals, To Contend That Only Humans Can Suffer. The Behavior Of Other Animals Renders Such Pretensions Specious. They Are Just Too Much Like Us.

But, Jefferson Worried That The People - And The Argument Goes Back To Thucydides And Aristotle - Are Easily Misled. He Also Stressed, Passionately And Repeatedly, That It Was Essential For The People To Understand The Risks And Benefits Of Government, To Educate Themselves, And To Involve Themselves In The Political Process. Without That, He Said, The Wolves Will Take Over.

Better The Hard Truth, I Say, Than The Comforting Fantasy.

Few Scientists Now Dispute That Today's Soaring Levels Of Carbon Dioxide And Other Gases In The Atmosphere Will Cause Global Temperature Averages To Rise By As Much As Nine Degrees Fahrenheit Sometime After The Year 2000.

The Suppression Of Uncomfortable Ideas May Be Common In Religion Or In Politics, But It Is Not The Path To Knowledge, And There's No Place For It In The Endeavor Of Science. We Do Not Know Beforehand Where Fundamental Insights Will Arise From About Our Mysterious And Lovely Solar System. The History Of Our Study Of Our Solar System Shows Us Clearly That Accepted And Conventional Ideas Are Often Wrong, And That Fundamental Insights Can Arise From The Most Unexpected Sources.

One Of The Great Commandments Of Science Is: 'mistrust Arguments From Authority.'

That Kind Of Skeptical, Questioning, "don't Accept What Authority Tells You" Attitude Of Science - Is Also Nearly Identical To The Attitude Of Mind Necessary For A Functioning Democracy. Science And Democracy Have Very Consonant Values And Approaches, And I Don't Think You Can Have One Without The Other.

Before We Invented Civilization Our Ancestors Lived Mainly In The Open Out Under The Sky. Before We Devised Artificial Lights And Atmospheric Pollution And Modern Forms Of Nocturnal Entertainment We Watched The Stars. There Were Practical Calendar Reasons Of Course But There Was More To It Than That. Even Today The Most Jaded City Dweller Can Be Unexpectedly Moved Upon Encountering A Clear Night Sky Studded With Thousands Of Twinkling Stars. When It Happens To Me After All These Years It Still Takes My Breath Away.

But I Could Be Wrong.

[science] Is Not Perfect. It Can Be Misused. It Is Only A Tool. But It Is By Far The Best Tool We Have, Self-correcting, Ongoing, Applicable To Everything. It Has Two Rules. First: There Are No Sacred Truths; All Assumptions Must Be Critically Examined; Arguments From Authority Are Worthless. Second: Whatever Is Inconsistent With The Facts Must Be Discarded Or Revised. ... The Obvious Is Sometimes False; The Unexpected Is Sometimes True.

All Over The World There Are Enormous Numbers Of Smart, Even Gifted, People Who Harbor A Passion For Science. But That Passion Is Unrequited. Surveys Suggest That Some 95% Of Americans Are "scientifically Illiterate." That's...the Same Fraction...of Slaves Who Were Illiterate Before The Civil War.

Has There Ever Been A Religion With The Prophetic Accuracy And Reliability Of Science? . . . No Other Human Institution Comes Close.

It Is The Responsibility Of Scientists Never To Suppress Knowledge, No Matter How Awkward That Knowledge Is, No Matter How It May Bother Those In Power; We Are Not Smart Enough To Decide Which Pieces Of Knowledge Are Permissible, And Which Are Not.

A Single Message From Space Will Show That It Is Possible To Live Through Technological Adolescence. . . . It Is Possible That The Future Of Human Civilization Depends On The Receipt Of Interstellar Messages.

Scientists Make Mistakes. Accordingly, It Is The Job Of The Scientist To Recognize Our Weakness, To Examine The Widest Range Of Opinions, To Be Ruthlessly Self-critical. Science Is A Collective Enterprise With The Error-correction Machinery Often Running Smoothly.

The Method Of Science Is Tried And True. It Is Not Perfect, It's Just The Best We Have. And To Abandon It, With Its Skeptical Protocols, Is The Pathway To A Dark Age.

The Size And Age Of The Cosmos Are Beyond Ordinary Human Understanding. Lost Somewhere Between Immensity And Eternity Is Our Tiny Planetary Home.

It's Perilous And Foolhardy For The Average Citizen To Remain Ignorant About Global Warming, Say, Or Ozone Depletion, Air Pollution, Toxic And Radioactive Wastes, Acid Rain, Topsoil Erosion, Tropical Deforestation, Exponential Population Growth. Jobs And Wages Depend On Science And Technology.

At The Heart Of Science Is An Essential Balance Between Two Seemingly Contradictory Attitudes-an Openness To New Ideas, No Matter How Bizarre Or Counterintuitive They May Be, And The Most Ruthless Skeptical Scrutiny Of All Ideas, Old And New. This Is How Deep Truths Are Winnowed From Deep Nonsense.

Each Of Us Is A Tiny Being, Permitted To Ride On The Outermost Skin Of One Of The Smaller Planets For A Few Dozen Trips Around The Local Star.

We've Begun At Last To Wonder About Our Origins, Star Stuff Contemplating The Stars, Organized Collections Of Ten Billion Billion Billion Atoms Contemplating The Evolution Of Matter, Tracing That Long Path By Which It Arrived At Consciousness Here On The Planet Earth And Perhaps Throughout The Cosmos. Our Obligation To Survive And Flourish Is Owed Not Just To Ourselves But Also To That Cosmos, Ancient And Vast, From Which We Spring.

We All Have A Thirst For Wonder. It's A Deeply Human Quality. Science And Religion Are Both Bound Up With It. What I'm Saying Is, You Don't Have To Make Stories Up, You Don't Have To Exaggerate. There's Wonder And Awe Enough In The Real World. Nature's A Lot Better At Inventing Wonders Than We Are.

The Idea That God Is An Oversized White Male With A Flowing Beard, Who Sits In The Sky And Tallies The Fall Of Every Sparrow Is Ludicrous. But If By 'god,' One Means The Set Of Physical Laws That Govern The Universe, Then Clearly There Is Such A God. This God Is Emotionally Unsatisfying... It Does Not Make Much Sense To Pray To The Law Of Gravity.
