We Can't Help It. Life Looks For Life.

Philosophers And Scientists Confidently Offer Up Traits Said To Be Uniquely Human, And The Monkeys And Apes Casually Knock Them Down -- Toppling The Pretension That Humans Constitute Some Sort Of Biological Aristocracy Among The Beings On Earth.

A Book Is Made From A Tree. It Is An Assemblage Of Flat, Flexible Parts (still Called "leaves") Imprinted With Dark Pigmented Squiggles. One Glance At It And You Hear The Voice Of Another Person, Perhaps Someone Dead For Thousands Of Years. Across The Millennia, The Author Is Speaking, Clearly And Silently, Inside Your Head, Directly To You. Writing Is Perhaps The Greatest Of Human Inventions, Binding Together People, Citizens Of Distant Epochs, Who Never Knew One Another. Books Break The Shackles Of Time ― Proof That Humans Can Work Magic.

We Are Prodding, Challenging, Seeking Contradictions Or Small, Persistent Residual Errors, Proposing Alternative Explanations, Encouraging Heresy. We Give Our Highest Rewards To Those Who Convincingly Disprove Established Beliefs.

Your Religion Assumes That People Are Children And Need A Boogeyman So They'll Behave. You Want People To Believe In God So They'll Obey The Law. That's The Only Means That Occurs To You: A Strict Secular Police Force, And The Threat Of Punishment By An All-seeing God For Whatever The Police Overlook. You Sell Human Beings Short.

What Counts Is Not What Sounds Plausible, Not What We Would Like To Believe, Not What One Or Two Witnesses Claim, But Only What Is Supported By Hard Evidence Rigorously And Skeptically Examined. Extraordinary Claims Require Extraordinary Evidence.

Every Cell Is A Triumph Of Natural Selection, And We’re Made Of Trillions Of Cells. Within Us, Is A Little Universe.

If Some Good Evidence For Life After Death Were Announced, I'd Be Eager To Examine It; But It Would Have To Be Real Scientific Data, Not Mere Anecdote. As With The Face On Mars And Alien Abductions, Better The Hard Truth, I Say, Than The Comforting Fantasy.

All Colours Are Arbitrary.

Thus The Recent Rapid Evolution Of Human Intelligence Is Not Only The Cause Of But Also The Only Conceivable Solution To The Many Serious Problems That Beset Us.

Science Is Only A Latin Word For Knowledge

The Illegality Of Cannabis Is Outrageous, An Impediment To Full Utilization Of A Drug Which Helps Produce The Serenity And Insight, Sensitivity And Fellowship So Desperately Needed In This Increasingly Mad And Dangerous World.

Dangerous World

The Values Of Science And The Values Of Democracy Are Concordant, In Many Cases Indistinguishable. Science And Democracy Began - In Their Civilized Incarnations - In The Same Time And Place, Greece In The Seventh And Sixth Centuries B.c. . . . Science Thrives On, Indeed Requires, The Free Exchange Of Ideas; Its Values Are Antithetical To Secrecy. Science Holds To No Special Vantage Points Or Privileged Positions. Both Science And Democracy Encourage Unconventional Opinions And Vigorous Debate. Both Demand Adequate Reason, Coherent Argument, Rigorous Standards Of Evidence And Honesty.

In The Long Run, The Aggressive Civilizations Destroy Themselves, Almost Always. It's Their Nature. They Can't Help It.

We Wish To Find The Truth, No Matter Where It Lies. But To Find The Truth We Need Imagination And Skepticism Both. We Will Not Be Afraid To Speculate, But We Will Be Careful To Distinguish Speculation From Fact.

Not Explaining Science Seems To Me Perverse. When You're In Love, You Want To Tell The World.

Where Did God Come From? If We Decide This Is An Unanswerable Question Why Not Save A Step And Conclude That The Origin Of The Universe Is An Unanswerable Question.

A Proclivity For Science Is Embedded Deeply Within Us, In All Times, Places, And Cultures. It Has Been The Means For Our Survival. It Is Our Birthright. When, Through Indifference, Inattention, Incompetence, Or Fear Of Skepticism, We Discourage Children From Science, We Are Disenfranchisin G Them, Taking From Them The Tools Needed To Manage Their Future.

Understanding Is A Kind Of Ecstasy

You Mean Am I For It Or Against It? You Think This Is A Key Question I'm Going To Be Asked On Vega, And You Want To Make Sure I Give The Right Answer? Okay. Overpopulation Is Why I'm In Favor Of Homosexuality And A Celibate Clergy. A Celibate Clergy Is An Especially Good Idea, Because It Tends To Suppress Any Hereditary Propensity Toward Fanaticism.

Extraordinary Observations Require Extraordinary Evidence To Make Them Believable.

It's A Lazy Saturday Afternoon, There's A Couple Lying Naked In Bed Reading Encyclopediea Brittannica To Each Other, And Arguing About Whether The Andromeda Galaxy Is More 'numinous' Than The Ressurection. Do They Know How To Have A Good Time, Or Don't They?

Advances In Medicine And Agriculture Have Saved Vastly More Lives Than Have Been Lost In All The Wars In History.

The Surface Of The Earth Is The Shore Of The Cosmic Ocean. From It We Have Learned Most Of What We Know. Recently, We Have Waded A Little Out To Sea, Enough To Dampen Our Toes Or, At Most, Wet Our Ankles. The Water Seems Inviting. The Ocean Calls.

There Are Wonders Enough Out There Without Our Inventing Any.

The Significance Of Our Lives And Our Fragile Planet Is Then Determined Only By Our Own Wisdom And Courage. We Are The Custodians Of Life's Meaning. We Long For A Parent To Care For Us, To Forgive Us Our Errors, To Save Us From Our Childish Mistakes. But Knowledge Is Preferable To Ignorance. Better By Far To Embrace The Hard Truth Than A Reassuring Fable. If We Crave Some Cosmic Purpose, Then Let Us Find Ourselves A Worthy Goal.

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.

What Does It Mean For A Civilisation To Be A Million Years Old? We Have Had Radio Telescopes And Spaceships For A Few Decades; Our Technical Civilisation Is A Few Hundred Years Old ... An Advanced Civilisation Millions Of Years Old Is As Much Beyond Us As We Are Beyond A Bushbaby Or A Macaque

For Years I've Been Stressing With Regard To Ufos That Extraordinary Claims Require Extraordinary Evidence.

It Means Nothing To Be Open To A Proposition We Don't Understand.

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

We Live In A Society Exquisitely Dependent On Science And Technology And Yet Have Cleverly Arranged Things So That Almost No One Understands Science And Technology.

For A Long Time The Human Instinct To Understand Was Thwarted By Facile Religious Explanations.

In Many Cultures It Is Customary To Answer That God Created The Universe Out Of Nothing. But This Is Mere Temporizing. If We Wish Courageously To Pursue The Question, We Must, Of Course Ask Next Where God Comes From? And If We Decide This To Be Unanswerable, Why Not Save A Step And Conclude That The Universe Has Always Existed?

The Secrets Of Evolution Are Death And Time-the Deaths Of Enormous Numbers Of Lifeforms That Were Imperfectly Adapted To The Environment; And Time For A Long Succession Of Small Mutations.

Chlorine Is A Deadly Poison Gas Employed On European Battlefields In World War I. Sodium Is A Corrosive Metal Which Burns Upon Contact With Water. Together They Make A Placid And Unpoisonous Material, Table Salt. Why Each Of These Substances Has The Properties It Does Is A Subject Called Chemistry.

The Cosmos Is Full Beyond Measure Of Elegant Truths; Of Exquisite Interrelationships; Of The Awesome Machinery Of Nature.

The Universe Is A Pretty Big Place. If It's Just Us, Seems Like An Awful Waste Of Space.

Ufos: The Reliable Cases Are Uninteresting And In The Interesting Cases Are Unreliable.

The Prediction I Can Make With The Highest Confidence Is That The Most Amazing Discoveries Will Be The Ones We Are Not Today Wise Enough To Foresee.

My Long-time View About Christianity Is That It Represents An Amalgam Of Two Seemingly Immiscible Parts-the Religion Of Jesus And The Religion Of Paul. Thomas Jefferson Attempted To Excise The Pauline Parts Of The New Testament. There Wasn't Much Left When He Was Done, But It Was An Inspiring Document.

You Have To Know The Past To Understand The Present.

An Atheist Is Someone Who Is Certain That God Does Not Exist, Someone Who Has Compelling Evidence Against The Existence Of God. I Know Of No Such Compelling Evidence. Because God Can Be Relegated To Remote Times And Places And To Ultimate Causes, We Would Have To Know A Great Deal More About The Universe Than We Do Now To Be Sure That No Such God Exists. To Be Certain Of The Existence Of God And To Be Certain Of The Nonexistence Of God Seem To Me To Be The Confident Extremes In A Subject So Riddled With Doubt And Uncertainty As To Inspire Very Little Confidence Indeed.

Billions And Billions.

The Desire To Be Connected With The Cosmos Reflects A Profound Reality, But We Are Connected; Not In The Trivial Ways That Astrology Promises, But In The Deepest Ways.

An Organism At War With Itself Is Doomed.

Is Mankind Alone In The Universe? Or Are There Somewhere Other Intelligent Beings Looking Up Into Their Night Sky From Very Different Worlds And Asking The Same Kind Of Question?

Sailors On A Becalmed Sea, We Sense The Stirring Of A Breeze.

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.

We Are, In A Way, Temporary Ambulatory Repositories For Our Nucleic Acids. This Does Not Deny Our Humanity; It Does Not Prevent Us From Pursuing The Good, The True And The Beautiful. But It Would Be A Great Mistake To Ignore Where We Have Come From In Our Attempt To Determine Where We Are Going.

But Down Deep, At The Molecular Heart Of Life We're Essentially Identical To Trees.

Finding The Occasional Straw Of Truth Awash In A Great Ocean Of Confusion And Bamboozle Requires Intelligence, Vigilance, Dedication, And Courage. But If We Don't Practice These Tough Habits Of Thought, We Cannot Hope To Solve The Truly Serious Problems That Face Us --- And We Risk Becoming A Nation Of Suckers, Up For Grabs By The Next Charlatan Who Comes Along.

Imagine We Could Accelerate Continuously At 1 G-what We're Comfortable With On Good Old Terra Firma-to The Midpoint Of Our Voyage, And Decelerate Continuously At 1 G Until We Arrive At Our Destination. It Would Take A Day To Get To Mars, A Week And A Half To Pluto, A Year To The Oort Cloud, And A Few Years To The Nearest Stars.

One Of The Saddest Lessons Of History Is This: If We’ve Been Bamboozled Long Enough, We Tend To Reject Any Evidence Of The Bamboozle. We’re No Longer Interested In Finding Out The Truth. The Bamboozle Has Captured Us. It’s Simply Too Painful To Acknowledge, Even To Ourselves, That We’ve Been Taken. Once You Give A Charlatan Power Over You, You Almost Never Get It Back.

Don't Judge Everyone Else By Your Own Limited Experience.

I Never Said It. Honest. Oh, I Said There Are Maybe 100 Billion Galaxies And 10 Billion Trillion Stars. It's Hard To Talk About The Cosmos Without Using Big Numbers. I Said "billion" Many Times On The Cosmos Television Series, Which Was Seen By A Great Many People. But I Never Said "billions And Billions." For One Thing, It's Too Imprecise. How Many Billions Are "billions And Billions"? A Few Billion? Twenty Billion? A Hundred Billion? "billions And Billions" Is Pretty Vague. When We Reconfigured And Updated The Series, I Checked-and Sure Enough, I Never Said It.

I Am Not An Atheist. An Atheist Is Someone Who Has Compelling Evidence That There Is No Judeo-christian-islamic God. I Am Not That Wise, But Neither Do I Consider There To Be Anything Approaching Adequate Evidence For Such A God. Why Are You In Such A Hurry To Make Up Your Mind? Why Not Simply Wait Until There Is Compelling Evidence?

[n]o Scientist Likes To Be Criticized. ... But You Don't Reply To Critics: "wait A Minute, Wait A Minute; This Is A Really Good Idea. I'm Very Fond Of It. It's Done You No Harm. Please Don't Attack It." That's Not The Way It Goes. The Hard But Just Rule Is That If The Ideas Don't Work, You Must Throw Them Away. Don't Waste Any Neurons On What Doesn't Work. Devote Those Neurons To New Ideas That Better Explain The Data. Valid Criticism Is Doing You A Favor.

The Notion That Science And Spirituality Are Somehow Mutually Exclusive Does A Disservice To Both.

If You Look At Earth From Space You See A Dot, That's Here. That's Home. That's Us. It Underscores The Responsibility To Deal More Kindly And Compassionately With One Another And To Preserve And Cherish That Pale Blue Dot, The Only Home We've Ever Known.

One Glance At A Book And You Hear The Voice Of Another Person, Perhaps Someone Dead For 1,000 Years. To Read Is To Voyage Through Time.

I Don?t Feel Rejected By The Sky. I?m A Part Of It- Tiny, To Be Sure, But Everything Is Tiny Compared To That Overwhelming Immensity.

Imagination Will Often Carry Us To Worlds That Never Were. But Without It We Go Nowhere.

Science Is An Attempt, Largely Successful, To Understand The World, To Get A Grip On Things, To Get Hold Of Ourselves, To Steer A Safe Course. Microbiology And Meteorology Now Explain What Only A Few Centuries Ago Was Considered Sufficient Cause To Burn Women To Death.

Except In Pure Mathematics, Nothing Is Known For Certain (although Much Is Certainly False).

Our Ancestors Worshipped The Sun, And They Were Not That Foolish. It Makes Sense To Revere The Sun And The Stars, For We Are Their Children.

I Set Before You Two Ways: You Can Use Your Technology To Destroy Yourselves Or To Carry You To The Planets And The Stars. It's Up To You.

We Live In An In-between Universe Where Things Change All Right...but According To Patterns, Rules, Or As We Call Them, Laws Of Nature.

I Would Love To Believe That When I Die I Will Live Again, That Some Thinking, Feeling, Remembering Part Of Me Will Continue. But As Much As I Want To Believe That, And Despite The Ancient And Worldwide Cultural Traditions That Assert An Afterlife, I Know Of Nothing To Suggest That It Is More Than Wishful Thinking.

.. Think Of The Rivers Of Blood Spilled By All Those Generals And Emperors So That In Glory And In Triumph They Could Become The 'momentary' Masters Of A 'fraction' Of A 'dot'

In More Than One Respect, The Exploring Of The Solar System And Homesteading Other Worlds Constitutes The Beginning, Much More Than The End, Of History.

For All Our Failings, Despite Our Limitations And Fallibilities, We Humans Are Capable Of Greatness.

Every Kid Starts Out As A Natural-born Scientist, And Then We Beat It Out Of Them. A Few Trickle Through The System With Their Wonder And Enthusiasm For Science Intact.

Whenever Our Ethnic Or National Prejudices Are Aroused, In Times Of Scarcity, During Challenges To National Self Esteem Or Nerve, When We Agonize About Our Diminished Cosmic Place And Purpose, Or When Fanaticism Is Bubbling Up Around Us - Then, Habits Of Thought Familiar From Ages Past Reach For The Controls.

There Is In This Universe Much Of What Seems To Be Design.

Organic As A Dandelion Seed, [the Ship Of Our Imagination] Will Carry Us To Worlds Of Dreams And Worlds Of Facts

The Open Road Still Softly Calls, Like A Nearly Forgotten Song Of Childhood

Science Is A Way To Not Fool Ourselves.

The Usual Rejoinder To Someone Who Says 'they Laughed At Columbus, They Laughed At Galileo' Is To Say 'but They Also Laughed At Bozo The Clown'.

Since World War Ii, Japan Has Spawned Enormous Numbers Of New Religions Featuring The Supernatural.... In Thailand, Diseases Are Treated With Pills Manufactured From Pulverized Sacred Scripture. Witches Are Today Being Burned In South Africa.... The Worldwide Tm [transcendental Meditation] Organization Has An Estimated Valuation Of $3 Billion. For A Fee, They Promise To Make You Invisible, To Enable You To Fly.

The Earth Is A Very Small Stage In A Vast Cosmic Arena. Think Of The Rivers Of Blood Spilled By All Those Generals And Emperors So That, In Glory And Triumph, They Could Become The Momentary Masters Of A Fraction Of A Dot. Think Of The Endless Cruelties Visited By The Inhabitants Of One Corner Of This Pixel On The Scarcely Distinguishable Inhabitants Of Some Other Corner, How Frequent Their Misunderstandings, How Eager They Are To Kill One Another, How Fervent Their Hatreds.

What Began In Deadly Competition Has Helped Us To See That Global Cooperation Is The Essential Precondition For Our Survival. Travel Is Broadening. It's Time To Hit The Road Again.

Cosmos Is A Greek Word For The Order Of The Universe. It Is, In A Way, The Opposite Of Chaos. It Implies The Deep Interconnectedness Of All Things. It Conveys Awe For The Intricate And Subtle Way In Which The Universe Is Put Together.

Man Is The Matter Of The Cosmos, Contemplating Itself.

Who Will Speak For Planet Earth?

[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.

Across The Sea Of Space, The Stars Are Other Suns.

Our Perceptions Are Fallible. We Sometimes See What Isn't There. We Are Prey To Optical Illusions. Occasionally We Hallucinate. We Are Error-prone.

Optical Illusions

We Are The Custodians Of Life's Meaning.

I Went To The Librarian And Asked For A Book About Stars.... And The Answer Was Stunning. It Was That The Sun Was A Star But Really Close. The Stars Were Suns, But So Far Away They Were Just Little Points Of Light.... The Scale Of The Universe Suddenly Opened Up To Me. It Was A Kind Of Religious Experience. There Was A Magnificence To It, A Grandeur, A Scale Which Has Never Left Me. Never Ever Left Me.

The Universe Is Not Required To Be In Perfect Harmony With Human Ambition.

Wisdom Lies In Understanding Our Limitations.

It Took The Church Until 1832 To Remove Galileo 's Work From Its List Of Books Which Catholics Were Forbidden To Read At The Risk Of Dire Punishment Of Their Immortal Souls.

There Are Many Other (besides Testosterone) Behaviour-eliciting Hormones Fundamental For Humen Well-being, Including Estrogen And Progesterone In Females. The Fact That Complex Behavioural Patterns Can Be Triggered By A Tiny Concentration Of Moleculas Coursing Through The Bloodstream, And That Different Animals Of The Same Species Generate Different Amounts Of These Hormones, Is Something Worth Thinking About When It's Time To Judge Such Matters As Free Will, Individual Responsibility, And Law And Order.

You Could Just As Well Say That An Agnostic Is A Deeply Religious Person With At Least A Rudimentary Knowledge Of Human Fallibility.

Somewhere, Something Incredible Is Waiting To Be Known.

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. Skeptical Scrutiny Is The Means, In Both Science And Religion, By Which Deep Thoughts Can Be Winnowed From Deep Nonsense.

I Would Love To Believe That When I Die I Will Live Again, That Some Thinking, Feeling, Remembering Part Of Me Will Continue.

One Of The Greatest Gifts Adults Can Give - To Their Offspring And To Their Society - Is To Read To Children.

We Are Made Of Star Stuff. For The Most Part, Atoms Heavier Than Hydrogen Were Created In The Interiors Of Stars And Then Expelled Into Space To Be Incorporated Into Later Stars. The Sun Is Probably A Third Generation Star.

We Live In A Society Exquisitely Dependent On Science And Technology, In Which Hardly Anyone Knows Anything About Science And Technology.

The Beauty Of A Living Thing Is Not The Atoms That Go Into It, But The Way Those Atoms Are Put Together.

With Insufficient Data It Is Easy To Go Wrong.

An Atheist Has To Know A Lot More Than I Know. An Atheist Is Someone Who Knows There Is No God. By Some Definitions Atheism Is Very Stupid.

There Is No God

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.

If All The Suns But Ours Collapsed Tonight, How Many Lifetimes Would It Take Us To Realize That We Were Alone?

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.

Our Children Long For Realistic Maps Of The Future That They Can Be Proud Of. Where Are The Cartographers Of Human Purpose?

How Is It That Hardly Any Major Religion Has Looked At Science And Concluded, “this Is Better Than We Thought! The Universe Is Much Bigger Than Our Prophets Said, Grander, More Subtle, More Elegant?” Instead They Say, “no, No, No! My God Is A Little God, And I Want Him To Stay That Way.” A Religion, Old Or New, That Stressed The Magnificence Of The Universe As Revealed By Modern Science Might Be Able To Draw Forth Reserves Of Reverence And Awe Hardly Tapped By The Conventional Faiths.

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.

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.

It Is Sometimes Said That Scientists Are Unromantic, That Their Passion To Figure Out Robs The World Of Beauty And Mystery. But Is It Not Stirring To Understand How The World Actually Works — That White Light Is Made Of Colors, That Color Is The Way We Perceive The Wavelengths Of Light, That Transparent Air Reflects Light, That In So Doing It Discriminates Among The Waves, And That The Sky Is Blue For The Same Reason That The Sunset Is Red? It Does No Harm To The Romance Of The Sunset To Know A Little Bit About It.

Science Is A Way Of Thinking That Helps You Not To Fool Yourself.

Your God Is Too Small For My Universe.

How Is It That Hardly Any Major Religion Has Looked At Science And Concluded, “this Is Better Than We Thought! The Universe Is Much Bigger Than Our Prophets Said, Grander, More Subtle, More Elegant?

Stars Are Phoenixes, Rising From Their Own Ashes.

Better By Far To Embrace The Hard Truth Than A Reassuring Fable. If We Crave Some Cosmic Purpose, Then Let Us Find Ourselves A Worthy Goal.

I Think If We Ever Reach The Point Where We Think We Thoroughly Understand Who We Are And Where We Came From, We Will Have Failed.

Skeptical Scrutiny Is The Means, In Both Science And Religion, By Which Deep Thoughts Can Be Winnowed From Deep Nonsense.

It Goes With A Courageous Intent To Greet The Universe As It Really Is, Not To Foist Our Emotional Predispositions On It But To Courageously Accept What Our Explorations Tell Us.

A New Consciousness Is Developing Which Sees The Earth As A Single Organism And Recognizes That An Organism At War With Itself Is Doomed. We Are One Planet.

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.

Those With The Courage To Explore The Weave And Structure Of The Cosmos, Even Where It Differs Profoundly From Their Wishes And Prejudices, Will Penetrate Its Deepest Mysteries.

For All I Know We May Be Visited By A Different Extraterrestrial Civilization Every Second Tuesday, But There's No Support For This Appealing Idea. The Extraordinary Claims Are Not Supported By Extraordinary Evidence.

We Are At A Crossroads In Human History. Never Before Has There Been A Moment So Simultaneously Perilous And Promising. We Are The First Species To Have Taken Evolution Into Our Own Hands.

The Nuclear Arms Race Is Like Two Sworn Enemies Standing Waist Deep In Gasoline, One With Three Matches, The Other With Five.

Cleverly Designed Experiments Are The Key.

Much Of Human History Can, I Think, Be Described As A Gradual And Sometimes Painful Liberation From Provincialism, The Emerging Awareness That There Is More To The World Than Was Generally Believed By Our Ancestors.

The Surface Of The Earth Is The Shore Of The Cosmic Ocean. On This Shore, We've Learned Most Of What We Know. Recently, We've Waded A Little Way Out, Maybe Ankle-deep, And The Water Seems Inviting. Some Part Of Our Being Knows This Is Where We Came From. We Long To Return, And We Can, Because The Cosmos Is Also Within Us. We're Made Of Star Stuff. We Are A Way For The Cosmos To Know Itself.

She Had Studied The Universe All Her Life, But Had Overlooked Its Clearest Message: For Small Creatures Such As We The Vastness Is Bearable Only Through Love.

Small Creatures

We Are Made Of Star-stuff. Our Bodies Are Made Of Star-stuff. There Are Pieces Of Star Within Us All.

First Rule In Government Spending: Why Build One When You Can Have Two At Twice The Price?

If Intelligence Is Our Only Edge, We Must Learn To Use It Better, To Shape It, To Understand Its Limitations And Deficiencies -- To Use It As Cats Use Stealth, As Katydids Use Camouflage -- To Make It The Tool Of Our Survival.

The Total Number Of Stars In The Universe Is Larger Than All The Grains Of Sand On All The Beaches Of The Planet Earth.

The Absence Of Evidence Is Not The Evidence Of Absence.

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.

What Distinguishes Our Species Is Thought. The Cerebral Cortex Is In A Way A Liberation. We Need No Longer Be Trapped In The Genetically Inherited Behavior Patterns Of Lizards And Baboons: Territoriality And Aggression And Dominance Hierarchies. We Are Each Of Us Largely Responsible For What Gets Put In To Our Brains. For What As Adults We Wind Up Caring For And Knowing About. No Longer At The Mercy Of The Reptile Brain We Can Change Ourselves. Think Of The Possibilities.

For All Its Material Advantages, The Sedentary Life Has Left Us Edgy, Unfulfilled, Even After 400 Generations In Villages And Cities, We Haven't Forgotten: The Open Road Still Softly Calls Like A Nearly Forgotten Song Of Childhood.

Absolute Certainty Will Always Elude Us. We Will Always Be Mired In Error. The Most Each Generation Can Hope For Is To Reduce The Error. . . .

You're An Interesting Species, An Interesting Mix. You're Capable Of Such Beautiful Dreams And Such Horrible Nightmares. You Feel So Lost, So Cut Off, So Alone, Only You're Not. See, In All Our Searching, The Only Thing We've Found That Makes The Emptiness Bearable Is Each Other.

I Can Find In My Undergraduate Classes, Bright Students Who Do Not Know That The Stars Rise And Set At Night, Or Even That The Sun Is A Star.

For Myself, I Like A Universe That, Includes Much That Is Unknown And, At The Same Time, Much That Is Knowable. A Universe In Which Everything Is Known Would Be Static And Dull, As Boring As The Heaven Of Some Weak-minded Theologians. A Universe That Is Unknowable Is No Fit Place For A Thinking Being. The Ideal Universe For Us Is One Very Much Like The Universe We Inhabit. And I Would Guess That This Is Not Really Much Of A Coincidence.

Both The Freudian And The Platonic Metaphors Emphasize The Considerable Independence Of And Tension Among The Constituent Parts Of The Psyche, A Point That Characterizes The Human Condition.

We Are Not Smart Enough To Decide Which Pieces Of Knowledge Are Permissible And Which Are Not.

The Evidence, So Far At Least And Laws Of Nature Aside, Does Not Require A Designer. Maybe There Is One Hiding, Maddeningly Unwilling To Be Revealed.

After The Earth Dies, Some 5 Billion Years From Now, After It's Burned To A Crisp, Or Even Swallowed By The Sun, There Will Be Other Worlds And Stars And Galaxies Coming Into Being - And They Will Know Nothing Of A Place Once Called Earth.

We Humans Look Rather Different From A Tree. Without A Doubt We Perceive The World Differently Than A Tree Does. But Down Deep, At The Molecular Heart Of Life, The Trees And We Are Essentially Identical.

Our Intelligence Is Imperfect, Surely, And Newly Arisen; The Ease With Which It Can Be Sweet-talked, Overwhelmed, Or Subverted By Other Hardwired Propensities - Sometimes Themselves Disguised As The Cool Light Of Reason - Is Worrisome.

In The Vastness Of The Cosmos There Must Be Other Civilizations Far Older And More Advanced Than Ours.

We Are Rare And Precious Because We Are Alive, Because We Can Think As Well As We Can. We Are Privileged To Influence And Perhaps Control Our Future. I Believe We Have An Obligation To Fight For Life On Earth - Not Just For Ourselves, But For All Those, Humans And Others, Who Came Before Us, And To Whom We Are Beholden, And For All Those Who, If We Are Wise Enough, Will Come After.

Books Are Like Seeds. They Can Lie Dormant For Centuries And Then Flower In The Most Unpromising Soil.

The Suppression Of Uncomfortable Ideas May Be Common In Religion Or In Politics, But It Is Not The Path To Knowledge; It Has No In The Endeavor Of Science. We Do Not Know In Advance Who Will Discover Fundamental Insights.

There Is Perhaps No Better A Demonstration Of The Folly Of Human Conceits Than This Distant Image Of Our Tiny World.

Which Aspects Of Our Nature Will Prevail Is Uncertain, Particularly When Our Visions And Prospects Are Bound To One Small Part Of The Small Planet Earth. But Up There In The Cosmos An Inescapable Perspective Awaits.

What's The Harm Of A Little Mystification? It Sure Beats Boring Statistical Analyses.

These Are All Cases Of Proved Or Presumptive Baloney. A Deception Arises, Sometimes Innocently But Collaboratively, Sometimes With Cynical Premeditation. Usually The Victim Is Caught Up In A Powerful Emotion -- Wonder, Fear, Greed, Grief. Credulous Acceptance Of Baloney Can Cost You Money; That's What P. T. Barnum Meant When He Said, 'there's A Sucker Born Every Minute.' But It Can Be Much More Dangerous Than That, And When Governments And Societies Lose The Capacity For Critical Thinking, The Results Can Be Catastrophic -- However Sympathetic We May Be To Those Who Have Bought The Baloney.

Recent Research Shows That Many Children Without Enough To Eat Wind Up With Diminished Capacity To Understand And Learn (“cognitive Impairment” ). Children Don't Have To Be Starving For This To Happen. Even Mild Undernourishment — The Kind Most Common Among Poor People In America — Can Do It.

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.

In Mozambique, The Story Goes, Monkeys Do Not Talk, Because They Know If They Utter Even A Single Word Some Man Will Come And Put Them To Work.

There Are As Many Atoms In One Molecule Of Dna As There Are Stars In A Typical Galaxy.

For Me, The Most Ironic Token Of [the First Human Moon Landing] Is The Plaque Signed By President Richard M. Nixon That Apollo 11 Took To The Moon. It Reads, ‘we Came In Peace For All Mankind.’ As The United States Was Dropping Seven And A Half Megatons Of Conventional Explosives On Small Nations In Southeast Asia, We Congratulated Ourselves On Our Humanity. We Would Harm No One On A Lifeless Rock.

Exploration Is In Our Nature. We Began As Wanderers, And We Are Wanderers Still. We Have Lingered Long Enough On The Shores Of The Cosmic Ocean. We Are Ready At Last To Set Sail For The Stars.

Many Religions Have Attempted To Make Statues Of Their Gods Very Large, And The Idea, I Suppose, Is To Make Us Feel Small. But If That's Their Purpose, They Can Keep Their Paltry Icons. We Need Only Look Up If We Wish To Feel Small.

If I Finish A Book A Week, I Will Read Only A Few Thousand Books In My Lifetime, About A Tenth Of A Percent Of The Contents Of The Greatest Libraries Of Our Time. The Trick Is To Know Which Books To Read.

These Days There Seems To Be Nowhere Left To Explore, At Least On The Land Area Of The Earth. Victims Of Their Very Success, The Explorers Now Pretty Much Stay Home.

Too Much Openness And You Accept Every Notion, Idea, And Hypothesis-which Is Tantamount To Knowing Nothing. Too Much Skepticism-especially Rejection Of New Ideas Before They Are Adequately Tested-and You're Not Only Unpleasantly Grumpy, But Also Closed To The Advance Of Science. A Judicious Mix Is What We Need.

As Agonizing A Disease As Cancer Is, I Do Not Think It Can Be Said That Our Civilization Is Threatened By It. ... But A Very Plausible Case Can Be Made That Our Civilization Is Fundamentally Threatened By The Lack Of Adequate Fertility Control. Exponential Increases Of Population Will Dominate Any Arithmetic Increases, Even Those Brought About By Heroic Technological Initiatives, In The Availability Of Food And Resources, As Malthus Long Ago Realized.

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. Sailors On A Becalmed Sea, We Sense A Stirring Of The Breeze.

Our Posturings, Our Imagined Self-importance , The Delusion That We Have Some Privileged Position In The Universe Are Challenged By This Point Of Pale Light.

If You Want To Make A [rhubarb] Pie From Scratch, First You Have To Create The Universe.

What A Splendid Perspective Contact With A Profoundly Different Civilization Might Provide! In A Cosmic Setting Vast And Old Beyond Ordinary Human Understanding We Are A Little Lonely, And We Ponder The Ultimate Significance, If Any, Of Our Tiny But Exquisite Blue Planet, The Earth.... In The Deepest Sense The Search For Extraterrestrial Intelligence Is A Search For Ourselves.

The Romans Called The Christians Atheists. Why? Well, The Christians Had A God Of Sorts, But It Wasn't A Real God. They Didn't Believe In The Divinity Of Apotheosized Emperors Or Olympian Gods. They Had A Peculiar, Different Kind Of God. So It Was Very Easy To Call People Who Believed In A Different Kind Of God Atheists. And That General Sense That An Atheist Is Anybody Who Doesn't Believe Exactly As I Do Prevails In Our Own Time.

There Are Naive Questions, Tedious Questions, Ill-phrased Questions, Questions Put After Inadequate Self-criticism. But Every Question Is A Cry To Understand The World. There Is No Such Thing As A Dumb Question.

Some 5 Billion Years From Now, There Will Be A Last Perfect Day On Earth... Then The Sun Will Begin To Die, Life Will Be Extinguished, The Oceans Will Boil And Evaporate Away.

The Fossil Record Implies Trial And Error, An Inability To Anticipate The Future, Features Inconsistent With An Efficient Great Designer (although Not With A Designer Of A More Remote And Indirect Temperament)

Trial And Error

Valid Criticism Does You A Favor.

What An Astonishing Thing A Book Is. It’s A Flat Object Made From A Tree With Flexible Parts On Which Are Imprinted Lots Of Funny Dark Squiggles. But One Glance At It And You’re Inside The Mind Of Another Person, Maybe Somebody Dead For Thousands Of Years. ... Books Break The Shackles Of Time. A Book Is Proof That Humans Are Capable Of Working Magic.

Once We Overcome Our Fear Of Being Tiny, We Find Ourselves On The Threshold Of A Vast And Awesome Universe That Utterly Dwarfs — In Time, In Space, And In Potential — The Tidy Anthropocentric Proscenium Of Our Ancestors.

Not All Birds Can Fly. What Separates The Flyers From The Walkers Is The Ability To Take Off.

The Fact That So Little Of The Findings Of Modern Science Is Prefigured In Scripture To My Mind Casts Further Doubt On It Divine Inspiration.

The Lifetime Of A Human Being Is Measured By Decades, The Lifetime Of The Sun Is A Hundred Million Times Longer. Compared To A Star, We Are Like Mayflies, Fleeting Ephemeral Creatures Who Live Out Their Lives In The Course Of A Single Day.

My Deeply Held Belief Is That If A God Of Anything Like The Traditional Sort Exists, Our Curiosity And Intelligence Is Provided By Such A God. We Would Be Unappreciative Of That Gift If We Suppressed Our Passion To Explore The Universe And Ourselves.

The Earth Is A Place. It Is By No Means The Only Place. It Is Not Even A Typical Place.

There Are In Fact 100 Billion Galaxies, Each Of Which Contain Something Like A 100 Billion Stars. Think Of How Many Stars, And Planets, And Kinds Of Life There May Be In This Vast And Awesome Universe.

A General Problem With Much Of Western Theology In My View Is That The God Portrayed Is Too Small. It Is A God Of A Tiny World And Not A God Of A Galaxy Much Less Of A Universe.

Books Are Key To Understanding The World And Participating In A Democratic Society.

I Believe That Part Of What Propels Science Is The Thirst For Wonder. It's A Very Powerful Emotion. All Children Feel It. In A First Grade Classroom Everybody Feels It; In A Twelfth Grade Classroom Almost Nobody Feels It, Or At Least Acknowledges It. Something Happens Between First And Twelfth Grade, And It's Not Just Puberty. Not Only Do The Schools And The Media Not Teach Much Skepticism, There Is Also Little Encouragement Of This Stirring Sense Of Wonder. Science And Pseudoscience Both Arouse That Feeling. Poor Popularizations Of Science Establish An Ecological Niche For Pseudoscience.

I Would Suggest That Science Is, At Least In My Part, Informed Worship.

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.
