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.

Personally, I Would Be Delighted If There Were A Life After Death, Especially If It Permitted Me To Continue To Learn About This World And Others, If It Gave Me A Chance To Discover How History Turns Out.

Other Things Being Equal, It Is Better To Be Smart Than To Be Stupid.

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

There Is No Other Species On Earth That Does Science. It Is, So Far, Entirely A Human Invention, Evolved By Natural Selection In The Cerebral Cortex For One Simple Reason: It Works. It 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.

Science Is A Way To Call The Bluff Of Those Who Only Pretend To Knowledge. It Is A Bulwark Against Mysticism, Against Superstition, Against Religion Misapplied To Where It Has No Business Being.

Any Sufficiently Crisp Question Can Be Answered By A Single Binary Digit-0 Or 1, Yes Or No.

Eratosthenes Was The Director Of The Great Library Of Alexandria, The Centre Of Science And Learning In The Ancient World. Aristotle Had Argued That Humanity Was Divided Into Greeks And Everybody Else, Whom He Called Barbarians And That The Greeks Should Keep Themselves Racially Pure. He Thought It Was Fitting For The Greeks To Enslave Other Peoples. But Erathosthenes Criticized Aristotle For His Blind Chauvinism, He Believed There Was Good And Bad In Every Nation.

The Cosmic Calendar Compresses The Local History Of The Universe Into A Single Year. If The Universe Began On January 1st It Was Not Until May That The Milky Way Formed. Other Planetary Systems May Have Appeared In June, July And August, But Our Sun And Earth Not Until Mid-september. Life Arose Soon After. We Humans Appear On The Cosmic Calendar So Recently That Our Recorded History Occupies Only The Last Few Seconds Of The Last Minute Of December 31st.

We Live On A Hunk Of Rock And Metal That Circles A Humdrum Star That Is One Of 400 Billion Other Stars That Make Up The Milky Way Galaxy Which Is One Of Billions Of Other Galaxies Which Make Up A Universe Which May Be One Of A Very Large Number, Perhaps An Infinite Number, Of Other Universes. That Is A Perspective On Human Life And Our Culture That Is Well Worth Pondering.

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

Since, In The Long Run, Every Planetary Society Will Be Endangered By Impacts From Space, Every Surviving Civilization Is Obliged To Become Spacefaring — Not Because Of Exploratory Or Romantic Zeal, But For The Most Practical Reason Imaginable: Staying Alive.

The Earth Is The Only World Known So Far To Harbor Life. There Is Nowhere Else, At Least In The Near Future, To Which Our Species Could Migrate. Visit, Yes. Settle, Not Yet. Like It Or Not, For The Moment The Earth Is Where We Make Our Stand. It Has Been Said That Astronomy Is A Humbling And Character-building Experience..... To Me, It Underscores Our Responsibility To Deal More Kindly With One Another, And To Preserve And Cherish The Pale Blue Dot, The Only Home We've Ever Known.

If We Long To Believe That The Stars Rise And Set For Us, That We Are The Reason There Is A Universe, Does Science Do Us A Disservice In Deflating Our Conceits?

I Maintain There Is Much More Wonder In Science Than In Pseudoscience. And In Addition, To Whatever Measure This Term Has Any Meaning, Science Has The Additional Virtue, And It Is Not An Inconsiderable One, Of Being True.

Science Is Not Perfect. It's Often Misused; It's Only A Tool, But It's The Best Tool We Have. Self-correcting , Ever Changing, Applicable To Everything: With This Tool, We Vanquish The Impossible.

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.

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.

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 Library Connects Us With The Insight And Knowledge, Painfully Extracted From Nature, Of The Greatest Minds That Ever Were, With The Best Teachers, Drawn From The Entire Planet And From All Our History, To Instruct Us Without Tiring, And To Inspire Us To Make Our Own Contribution To The Collective Knowledge Of The Human Species.

Frederick Douglas Taught That Literacy Is The Path From Slavery To Freedom. There Are Many Kinds Of Slavery And Many Kinds Of Freedom, But Reading Is Still The Path.

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.

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

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.

But I Could Be Wrong.

It Is Said That Men May Not Be The Dreams Of The God, But Rather That The Gods Are The Dreams Of Men.

The Claim Is Also Sometimes Made That Science Is As Arbitrary Or Irrational As All Other Claims To Knowledge, Or That Reason Itself Is An Illusion. As Ethan Allen Said Those Who Invalidate Reason Ought Seriously To Consider Whether They Argue Against Reason With Or Without Reason; If With Reason, Then They Establish The Principle That They Are Labouring To Dethrone. If They Argue Without Reason, Which They Must Do, In Order To Be Consistent With Themselves, They Are Out Of Reach Of Rational Conviction, Nor Do They Deserve A Rational Argument.

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

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.

The Cosmos Is All That Is Or Was Or Ever Will Be. Our Feeblest Contemplations Of The Cosmos Stir Us -- There Is A Tingling In The Spine, A Catch In The Voice, A Faint Sensation, As If A Distant Memory, Of Falling From A Height. We Know We Are Approaching The Greatest Of Mysteries.

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.

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.

Modern Darwinism Makes It Abundantly Clear That Many Less Ruthless Traits, Some Not Always Admired By Robber Barons And Fuhrers - Altruism, General Intelligence, Compassion - May Be The Key To Survival.

Religions Are Tough. Either They Make No Contentions Which Are Subject To Disproof Or They Quickly Redesign Doctrine After Disproof. ... Near The Core Of The Religious Experience Is Something Remarkably Resistant To Rational Inquiry.

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

Indeed The Reasoned Criticism Of A Prevailing Belief Is A Service To The Proponents Of That Belief; If They Are Incapable Of Defending It, They Are Well Advised To Abandon It. This Self-questioning And Error-correcting Aspect Of The Scientific Method Is Its Most Striking Property.

Self Questioning

What A Marvelous Cooperative Arrangement - Plants And Animals Each Inhaling Each Other's Exhalations, A Kind Of Planet-wide Mutual Mouth-to-stoma Resuscitation, The Entire Elegant Cycle Powered By A Star 150 Million Kilometers Away.

The Dumbing Down Of America Is Evident In The Slow Decay Of Substantive Content, A Kind Of Celebration Of Ignorance.

There Are Many Instances In Science, Where Those Closest To The Intricacies Of The Subject Have A More Highly Developed Sense Of Its Intractability Than Those At Some Remove. On The Other Hand, Those At Too Great A Distance May, I Am Well Aware, Mistake Ignorance For Perspective.

Because Men, Compared To Male Chimps, Have Such Relatively Small Testicles (large Testicles Indicate A Species Where Many Males Mate, One After The Other, With The Same Female), We Might Guess That Promiscuous Societies Were Uncommon In The Immediate Human Past.

The Sacred Truth Of Science Is That There Are No Sacred Truths.

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

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.

The Hole In The Ozone Layer Is A Kind Of Skywriting. At First It Seemed To Spell Out Our Continuing Complacency Before A Witch's Brew Of Deadly Perils. But Perhaps It Really Tells Of A Newfound Talent To Work Together To Protect The Global Environment.

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.

After I Give Lectures-on Almost Any Subject-i Am Often Asked, "do You Believe In Ufos?" I'm Always Struck By How The Question Is Phrased, The Suggestion That This Is A Matter Of Belief And Not Evidence. I'm Almost Never Asked, "how Good Is The Evidence That Ufos Are Alien Spaceships?"

How Smart Does A Chimpanzee Have To Be Before Killing Him Constitutes Murder?

If We Teach Only The Findings And Products Of Science - No Matter How Useful And Even Inspiring They May Be - Without Communicating Its Critical Method, How Can The Average Person Possibly Distinguish Science From Pseudoscience?

It Seems Madness To Say, 'we're Worried That They're Going To Become Addicted To Marijuana' -- There's No Evidence Whatever That It's An Addictive Drug, But Even If It Were, These People Are Dying, What Are We Saving Them From?

It Will Not Be We Who Reach Alpha Centauri, And The Other Nearby Stars. It Will Be A Species Very Like Us - But With More Of Our Strengths And Fewer Of Our Weaknesses.

Every Time You Look Up At The Sky, Every One Of Those Points Of Light Is A Reminder That Fusion Power Is Extractable From Hydrogen And Other Light Elements, And It Is An Everyday Reality Throughout The Milky Way Galaxy.

Writing Is Perhaps The Greatest Of Human Inventions, Binding Together People Who Never Knew Each Other, Citizens Of Distant Epochs. Books Break The Shackles Of Time. A Book Is Proof That Humans Are Capable Of Magic.

The Open Road Still Softly Calls.

Perhaps The Depth Of Love Can Be Calibrated By The Number Of Different Selves That Are Actively Involved In A Given Relationship.

In Exchange For Freedom Of Inquiry, Scientists Are Obliged To Explain Their Work.

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.

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

The Immense Distances To The Stars And The Galaxies Mean That We See Everything Ins Pace Int He Past, Some As They Were Before The Earth Came To Be. Telescopes Are Time Machines.

The Politicians And The Religious Leaders And The Weapons Scientists Have Been At It For A Long Time And They've Made A Thorough Mess Of It. I Mean, We're In Deep Trouble.

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

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.

We Are An Intelligent Species And The Use Of Our Intelligence Quite Properly Gives Us Pleasure. In This Respect The Brain Is Like A Muscle. When We Think Well, We Feel Good. Understanding Is A Kind Of Ecstasy.

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

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

In The Deepest Sense The Search For Extraterrestrial Intelligence Is A Search For Ourselves.

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.

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.

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.

While Our Behavior Is Still Significantly Controlled By Our Genetic Inheritance, We Have, Through Our Brains, A Much Richer Opportunity To Blaze New Behavioral And Cultural Pathways On Short Timescales.

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 Italy, The Inquisition Was Condemning People To Death Until The End Of The Eighteenth Century, And Inquisitional Torture Was Not Abolished In The Catholic Church Until 1816. The Last Bastion Of Support For The Reality Of Witchcraft And The Necessity Of Punishment Has Been The Christian Churches.

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.

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.

Science Is A Way Of Thinking Much More Than It Is A Body Of Knowledge.

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.

As The Ancient Myth Makers Knew, We Are Children Equally Of The Earth And The Sky.

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.

Be Grateful Everyday For The Brief But Magnificent Opportunity That Life Provides.

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.

Any Faith That Admires Truth, That Strives To Know God, Must Be Brave Enough To Accommodate The Universe.

We Are The Product Of 4.5 Billion Years Of Fortuitous, Slow Biological Evolution. There Is No Reason To Think That The Evolutionary Process Has Stopped. Man Is A Transitional Animal. He Is Not The Climax Of Creation.

The Hindu Religion Is The Only Of The World's Great Faiths Dedicated To The Idea That The Cosmos Itself Undergoes An Immense, Indeed An Infinite, Number Of Deaths And Rebirths.

When A Honeybee Dies It Releases A Death Pheromone, A Characteristic Odour That Signals The Survivors To Remove It From The Hive. The Corpse Is Promptly Pushed And Tugged Out Of The Hive. The Death Pheromone Is Oleic Acid. What Happens If A Live Bee Is Dabbed With A Drop Of Oleic Acid? Then No Matter How Strapping And Vigourous It Might Be, It Is Carried Kicking And Screaming Out Of The Hive.

I Consider It An Extremely Dangerous Doctrine, Because The More Likely We Are To Assume That The Solution Comes From The Outside, The Less Likely We Are To Solve Our Problems Ourselves.

Books Break The Shackles Of Time, Proof That Humans Can Work Magic.

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.

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.

Wisdom Lies In Understanding Our Limitations.

Man Is A Transitional Animal. He Is Not The Climax Of Creation

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

Perhaps, In Retrospect, There Would Be Little Motivation Even For Malevolent Extraterrestrials To Attack The Earth; Perhaps, After A Preliminary Survey, They Might Decide It Is More Expedient Just To Be Patient For A Little While And Wait For Us To Self-destruct.

In A Complex Universe, In A Society Undergoing Unprecedented Change, How Can We Find The Truth If We Are Not Willing To Question Everything And To Give A Fair Hearing To Everything?

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.

Our Passion For Learning ... Is Our Tool For Survival.

If Our Long-term Survival Is At Stake, We Have A Basic Responsibility To Our Species To Venture To Other Worlds. Sailors On A Becalmed Sea, We Sense The Stirring Of A Breeze.

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.

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

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. Sooner Or Later Such A Religion Will Emerge.

All Of Us Cherish Our Beliefs. They Are, To A Degree, Self-defining. When Someone Comes Along Who Challenges Our Belief System As Insufficiently Well-based - Or Who, Like Socrates, Merely Asks Embarrassing Questions That We Haven't Thought Of, Or Demonstrates That We've Swept Key Underlying Assumptions Under The Rug - It Becomes Much More Than A Search For Knowledge. It Feels Like A Personal Assault.

Embarrassing Questions

It Would Be Wryly Interesting If In Human History The Cultivation Of Marijuana Led Generally To The Invention Of Agriculture, And Thereby To Civilization.

Billions And Billions.

We Go About Our Daily Lives Understanding Almost Nothing Of The World.

Your God Is Too Small For My Universe.

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.

Scientists Can Routinely Predict A Solar Eclipse, To The Minute, A Millennium In Advance. You Can Go To The Witch Doctor To Lift The Spell That Causes Your Pernicious Anaemia, Or You Can Take Vitamin B12. If You Want To Save Your Child From Polio, You Can Pray Or You Can Inoculate. If You're Interested In The Sex Of Your Unborn Child, You Can Consult Plumb-bob Danglers All You Want . . . But They'll Be Right, On Average, Only One Time In Two. If You Want Real Accuracy . . . Try Amniocentesis And Sonograms. Try Science.

If We Ruin The Earth, There Is No Place Else To Go

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.

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.

At The Extremes It Is Difficult To Distinguish Pseudoscience From Rigid, Doctrinaire Religion.

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

But The Fact That Some Geniuses Were Laughed At Does Not Imply That All Who Are Laughed At Are Geniuses. They Laughed At Columbus, They Laughed At Fulton, They Laughed At The Wright Brothers. But They Also Laughed At Bozo The Clown.

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

It Is Far Better To Grasp The Universe As It Really Is Than To Persist In Delusion, However Satisfying And Reassuring.

National Boundaries Are Not Evident When We View The Earth From Space. Fanatical Ethnic Or Religious Or National Chauvinisms Are A Little Difficult To Maintain When We See Our Planet As A Fragile Blue Crescent Fading To Become An Inconspicuous Point Of Light Against The Bastion And Citadel Of The Stars.

We Are, Each Of Us, A Multitude. Within Us Is A Little Universe.

Societies Will, Of Course, Wish To Exercise Prudence In Deciding Which Technologies That Is, Which Applications Of Science Are To Be Pursued And Which Not. But Without Funding Basic Research, Without Supporting The Acquisition Of Knowledge For Its Own Sake, Our Options Become Dangerously Limited.

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.

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.

I Believe Our Future Depends Powerfully On How Well We Understand This Cosmos In Which We Float, Like A Mote Of Dust In The Morning Sky.

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.

In All Our Searching, The Only Thing We've Found That Makes The Emptiness Bearable Is Each Other.

I Find Science So Much More Fascinating Than Science Fiction. It Also Has The Advantage Of Being True.

The Understanding Of The Intent Of The Artist Which I Can Achieve When High Sometimes Carries Over To When I’m Down. This Is One Of Many Human Frontiers Which Cannabis Has Helped Me Traverse.

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. Home You Think. Home. This Is My World. This Is Where I Come From. Everyone I Know, Everyone I Ever Heard Of, Grew Up Down There, Under That Relentless And Exquisite Blue.

Writing Is Perhaps The Greatest Of Human Inventions.

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.

If There Is Life, Then I Believe We Should Do Nothing To Disturb That Life. Mars Then, Belongs To The Martians, Even If They Are Microbes.

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

Accommodation To Change, The Thoughtful Pursuit Of Alternative Futures Are Keys To The Survival Of Civilization And Perhaps Of The Human Species.

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.

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

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.

Ask Courageous Questions. Do Not Be Satisfied With Superficial Answers. Be Open To Wonder And At The Same Time Subject All Claims To Knowledge, Without Exception, To Intense Skeptical Scrutiny. Be Aware Of Human Fallibility. Cherish Your Species And Your Planet.

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

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.

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.

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.

One Of The Great Commandments Of Science Is, 'mistrust Arguments From Authority'. (scientists, Being Primates, And Thus Given To Dominance Hierarchies, Of Course Do Not Always Follow This Commandment.)

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.

We Have Entered, Almost Without Noticing, An Age Of Exploration And Discovery Unparalleled Since The Renaissance.

The Big Bang Is Our Modern Scientific Creation Myth. It Comes From The Same Human Need To Solve The Cosmological Riddle [where Did The Universe Come From?]

There Are More Potential Combinations Of Dna [physical Forms] Than There Are Atoms In The Universe.

You Mustn't Think Of The Universe As A Wilderness. It Hasn't Been That For Billions Of Years," He Said. "think Of It More As... ..cultivated.

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.

Time Spent With Children Is Time Well Spent. Their Little Minds Are Not Constrained By 'reality' Or Focused Upon Goals. Anything And Everything Is Possible. Imagination Will Often Carry Us To Worlds That Never Were. But Without It We Go Nowhere.

There Are Many Hypotheses In Physics Of Almost Comparable Brillance And Elegance That Have Been Rejected Because They Did Not Survive Such A Confrontation With Experiment. In My View, The Human Condition Would Be Greatly Improved If Such Confrontations And Willingness To Reject Hypotheses Were A Regular Part Of Our Social, Political, Economic, Religious And Cultural Lives.

So Those Who Wished For Some Central Cosmic Purpose For Us, Or At Least Our World, Or At Least Our Solar System, Or At Least Our Galaxy, Have Been Disappointed, Progressively Disappointed. The Universe Is Not Responsive To Our Ambitious Expectations.

Our Concern For The Future Can Be Tested By How Well We Support Our Libraries.

We Can Judge Our Progress By The Courage Of Our Questions And The Depth Of Our Answers, Our Willingness To Embrace What Is True Rather Than What Feels Good.

I'm Only A Four-dimensional Creature. Haven't Got A Clue How To Visualise Infinity. Even Einstein Hadn't. I Know Because I Asked Him

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.

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.

But I Try Not To Think With My Gut. If I'm Serious About Understanding The World, Thinking With Anything Besides My Brain, As Tempting As That Might Be, Is Likely To Get Me Into Trouble.

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

If You Are Only Skeptical, Then No New Ideas Make It Through To You. You Become A Crotchety Old Person Convinced That Nonsense Is Ruling The World. (there Is, Of Course, Much Data To Support You.) But Every Now And Then, A New Idea Turns Out To Be On The Mark, Valid And Wonderful. If You Are Too Much In The Habit Of Being Skeptical About Everything, You Are Going To Miss Or Resent It, And Either Way You Will Be Standing In The Way Of Understanding And Progress.

Preserve And Cherish The Pale Blue Dot, The Only Home We've Ever Known.

All Inquiries Carry With Them Some Element Of Risk.

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.

Somewhere, Something Incredible Is Waiting To Be Known.

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.

The Bill Of Rights Decoupled Religion From The State, In Part Because So Many Religions Were Steeped In An Absolutist Frame Of Mind - Each Convinced That It Alone Had A Monopoly On The Truth And Therefore Eager For The State To Impose This Truth 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.

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.

[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.

Present Global Culture Is A Kind Of Arrogant Newcomer. It Arrives On The Planetary Stage Following Four And A Half Billion Years Of Other Acts, And After Looking About For A Few Thousand Years Declares Itself In Possession Of Eternal Truths. But In A World That Is Changing As Fast As Ours, This Is A Prescription For Disaster. No Nation, No Religion, No Economic System, No Body Of Knowledge, Is Likely To Have All The Answers For Our Survival. There Must Be Many Social Systems That Would Work Far Better Than Any Now In Existence. In The Scientific Tradition, Our Task Is To Find Them.

Teller Contended, Not Implausibly, That Hydrogen Bombs Keep The Peace, Or At Least Prevent Thermonuclear War, Because The Consequences Of Warfare Between Nuclear Powers Are Now Too Dangerous. We Haven't Had A Nuclear War Yet, Have We? But All Such Arguments Assume That The Nuclear-armed Nations Are And Always Will Be, Without Exception, Rational Actors, And That Bouts Of Anger And Revenge And Madness Will Never Overtake Their Leaders (or Military And Secret Police Officers In Charge Of Nuclear Weapons). In The Century Of Hitler And Stalin, This Seems Ingenuous.
