Evolving Life Must Experience A Vast Range Of Possibilities, Based On Environmental Histories So Unpredictable That No Realized Route - The Pathway To Consciousness In The Form Of Homo Sapiens Or Little Green Men, For Example - Can Be Construed As A Highway To Heaven, But Must Be Viewed As A Tortuous Track Rutted With Uncountable Obstacles And Festooned With Innumerable Alternative Branches. Any Reasonably Precise Repetition Of Our Earthly Route On Another Planet Therefore Becomes Wildly Improbable Even In A Trillion Cases.

More From Stephen Jay Gould

No More Harmful Nonsense Exists Than [the] Common Supposition That Deepest Insight Into Great Questions About The Meaning Of Life Or The Structure Of Reality Emerges Most Readily When A Free, Undisciplined, And Uncluttered (read, Rather, Ignorant And Uneducated) Mind Soars Above Mere Earthly Knowledge And Concern.

I Like To Summarize What I Regard As The Pedestal-smashing Messages Of Darwin's Revolution In The Following Statement, Which Might Be Chanted Several Times A Day, Like A Hare Krishna Mantra, To Encourage Penetration Into The Soul: Humans Are Not The End Result Of Predictable Evolutionary Progress, But Rather A Fortuitous Cosmic Afterthought.

We Can Now Determine, Easily And Relatively Cheaply, The Detailed Chemical Architecture Of Genes ; And We Can Trace The Products Of These Genes ( Enzymes And Proteins ) As They Influence The Course Of Embryology . In So Doing We Have Made The Astounding Discovery That All Complex Animal Phyla - Arthropods And Vertebrates In Particular - Have Retained, Despite Their Half-billion Years Of Evolutionary Independence, An Extensive Set Of Common Genetic Blueprints For Building Bodies.

We Are The Offspring Of History, And Must Establish Our Own Paths In This Most Diverse And Interesting Of Conceivable Universes—one Indifferent To Our Suffering, And Therefore Offering Us Maximum Freedom To Thrive, Or To Fail, In Our Own Chosen Way.

I Was Lucky To Wander Into Evolutionary Theory, One Of The Most Exciting And Important Of All Scientific Fields. I Had Never Heard Of It When I Started At A Rather Tender Age; I Was Simply Awed By Dinosaurs. I Thought Paleontologists Spent Their Lives Digging Up Bones And Putting Them Together, Never Venturing Beyond The Momentous Issue Of What Connects To What. Then I Discovered Evolutionary Theory. Ever Since Then, The Duality Of Natural History-richness In Particularities And Potential Union In Underlying Explanation-has Propelled Me.

We Live In An Essential And Unresolvable Tension Between Our Unity With Nature And Our Dangerous Uniqueness. Systems That Attempt To Place And Make Sense Of Us By Focusing Exclusively Either On The Uniqueness Or The Unity Are Doomed To Failure. But We Must Not Stop Asking And Questing Because The Answers Are Complex And Ambiguous.

Darwinian Natural Selection Only Yields Adaptation To Changing Local Environments, And Better Function In An Immediate Habitat Might Just As Well Be Achieved By Greater Simplicity In Form And Behavior As By Ever-increasing Complexity.

I Picture Several Reviewers Of My Own Books As Passing A Long Future Lodged Between Brutus And Judas In The Jaws Of Satan.

Theory And Fact Are Equally Strong And Utterly Interdependent; One Has No Meaning Without The Other. We Need Theory To Organize And Interpret Facts, Even To Know What We Can Or Might Observe. And We Need Facts To Validate Theories And Give Them Substance.

The Human Mind Delights In Finding Pattern—so Much So That We Often Mistake Coincidence Or Forced Analogy For Profound Meaning. No Other Habit Of Thought Lies So Deeply Within The Soul Of A Small Creature Trying To Make Sense Of A Complex World Not Constructed For It.

Orchids Were Not Made By An Ideal Engineer; They Are Jury-rigged From A Limited Set Of Available Components.

The Basic Formulation, Or Bare-bones Mechanics, Of Natural Selection Is A Disarmingly Simple Argument, Based On Three Undeniable Facts (overproduction Of Offspring, Variation, And Heritability) And One Syllogistic Inference (natural Selection, Or The Claim That Organisms Enjoying Differential Reproductive Success Will, On Average, Be Those Variants That Are Fortuitously Better Adapted To Changing Local Environments, And That These Variants Will Then Pass Their Favored Traits To Offspring By Inheritance).

People Talk About Human Intelligence As The Greatest Adaptation In The History Of The Planet. It Is An Amazing And Marvelous Thing, But In Evolutionary Terms, It Is As Likely To Do Us In As To Help Us Along.

When People Learn No Tools Of Judgment And Merely Follow Their Hopes, The Seeds Of Political Manipulation Are Sown.

Our Current Drug Crisis Is A Tragedy Born Of A Phony System Of Classification. For Reasons That Are Little More Than Accidents Of History, We Have Divided A Group Of Nonfood Substances Into Two Categories: Items Purchasable For Supposed Pleasure (such As Alcohol), And Illicit Drugs.

If A Man Dies Of Cancer In Fear And Despair, Then Cry For His Pain And Celebrate His Life. The Other Man, Who Fought Like Hell And Laughed In The End, But Also Died, May Have Had An Easier Time In His Final Months, But Took His Leave With No More Humanity.

The World Is Full Of Signals That We Don't Perceive.

Nature Is What She Is - Amoral And Persistent.

The History Of Life Is A Tale Of Decimation And Later Stabilization Of Few Surviving Anatomies, Not A Story Of Steady Expansion And Progress.

If We Make This Readjustment To View Homo Sapiens As An Ultimate In Oddball Rarity, And Life At Bacterial Grade As The Common Expression Of A Universal Phenomenon, Then We Could Finally Ask The Truly Fundamental Question Raised By The Prospect Of Martian Fossils. If Life Originates As A General Property Of The Material Universe Under Certain Conditions (probably Often Realized), Then How Much Can The Basic Structure And Constitution Of Life Vary From Place To Independent Place?

For Dawkins, Evolution Is A Battle Among Genes, Each Seeking To Make More Copies Of Itself. Bodies Are Merely The Places Where Genes Aggregate For A Time.

We Are Here Because One Odd Group Of Fishes Had A Peculiar Fin Anatomy That Could Transform Into Legs For Terrestrial Creatures; Because The Earth Never Froze Entirely During An Ice Age; Because A Small And Tenuous Species, Arising In Africa A Quarter Of A Million Years Ago, Has Managed, So Far, To Survive By Hook And By Crook. We May Yearn For A ‘higher Answer’– But None Exists

Still, Our Creationist Incubi, Who Would Never Let Facts Spoil A Favorite Argument, Refuse To Yield, And Continue To Assert The Absence Of All Transitional Forms By Ignoring Those That Have Been Found, And Continuing To Taunt Us With Admittedly Frequent Examples Of Absence.

History Employs Evolution To Structure Biological Events In Time.

Each Worldview Was A Cultural Product, But Evolution Is True And Separate Creation Is Not. [...] Worldviews Are Social Constructions, And They Channel The Search For Facts. But Facts Are Found And Knowledge Progresses, However Fitfully. Fact And Theory Are Intertwined, And All Great Scientists Understand The Interaction.

Wind Back The Tape Of Life To The Early Days Of The Burgess Shale; Let It Play Again From An Identical Starting Point, And The Chance Becomes Vanishingly Small That Anything Like Human Intelligence Would Grace The Replay.

Contingency Is A Thing Unto Itself, Not The Titration Of Determinism By Randomness.

The Facts Of Nature Are What They Are, But We Can Only View Them Through The Spectacles Of Our Mind. Our Mind Works Largely By Metaphor And Comparison, Not Always (or Often) By Relentless Logic. When We Are Caught In Conceptual Traps, The Best Exit Is Often A Change In Metaphor Not Because The New Guideline Will Be Truer To Nature (for Neither The Old Nor The New Metaphor Lies "out There" In The Woods), But Because We Need A Shift To More Fruitful Perspectives, And Metaphor Is Often The Best Agent Of Conceptual Transition.

Evolution Is An Inference From Thousands Of Independent Sources, The Only Conceptual Structure That Can Make Unified Sense Of All This Disparate Information.

The Journalistic Tradition So Exalts Novelty And Flashy Discovery, As Reputable And Newsworthy, That Standard Accounts For The Public Not Only Miss The Usual Activity Of Science But Also, And More Unfortunately, Convey A False Impression About What Drives Research.

'creation Science' Has Not Entered The Curriculum For A Reason So Simple And So Basic That We Often Forget To Mention It: Because It Is False, And Because Good Teachers Understand Exactly Why It Is False.

Creation Science

All Evolutionary Biologists Know That Variation Itself Is Nature's Only Irreducible Essence... I Had To Place Myself Amidst The Variation.

If There Is Any Consistent Enemy Of Science, It Is Not Religion, But Irrationalism.

What An Odd Time To Be A Fundamentalist About Adaptation And Natural Selection - When Each Major Subdiscipline Of Evolutionary Biology Has Been Discovering Other Mechanisms As Adjuncts To Selection's Centrality.

Complex Organisms Cannot Be Construed As The Sum Of Their Genes, Nor Do Genes Alone Build Particular Items Of Anatomy Or Behavior By Themselves. Most Genes Influence Several Aspects Of Anatomy And Behavior As They Operate Through Complex Interactions With Other Genes And Their Products, And With Environmental Factors Both Within And Outside The Developing Organism. We Fall Into A Deep Error, Not Just A Harmful Oversimplification, When We Speak Of Genes "for" Particular Items Of Anatomy Or Behavior.

Interaction With Others

[t]he Effects Of General Change [in Literature] Are Most Tellingly Recorded Not In Alteration Of The Best Products, But In The Transformation Of The Most Ordinary Workaday Books; For When Potboilers Adopt The New Style, Then The Revolution Is Complete.

People Are Storytelling Creatures. We Like Stories That Go Somewhere, And Therefore We Like Trends - Because Trends Are Things That Either Get Better Or Get Worse, So We Can Either Rejoice Or Lament. But We Mistakenly Depict Many Things As Trends Moving In Some Direction. We Take The "full House" Of Variation In A System And Try To Represent It As A Single Number, When In Fact What We Should Be Doing Is Studying The Variation As It Expands And Contracts. If You Look At The History Of The Variation In All Its Complexity, Then You See There's No Trend.

Current Utility And Historical Origin Are Different Subjects.

When Scientists Need To Explain Difficult Points Of Theory, Illustration By Hypothetical Example - Rather Than By Total Abstraction - Works Well (perhaps Indispensably) As A Rhetorical Device. Such Cases Do Not Function As Speculations In The Pejorative Sense - As Silly Stories That Provide Insight Into Complex Mechanisms - But Rather As Idealized Illustrations To Exemplify A Difficult Point Of Theory. (other Fields, Like Philosophy And The Law, Use Such Conjectural Cases As A Standard Device.

Anything, Even The Conceptually Most Complex Material, Can Be Written For General Audiences Without Any Dumbing Down. Of Course You Have To Explain Things Carefully. This Goes Back To Galileo, Who Wrote His Great Books As Dialogues In Italian, Not As Treatises In Latin. And To Darwin, Who Wrote The Origin Of Species For General Readers. I Think A Lot Of People Pick Up Darwin's Book And Assume It Must Be A Popular Version Of Some Technical Monograph, But There Is No Technical Monograph. That's What He Wrote. So What I'm Doing Is Part Of A Great Humanistic Tradition.

Without A Commitment To Science And Rationality In Its Proper Domain, There Can Be No Solution To The Problems That Engulf Us. Still, The Yahoos Never Rest.

The Enemy Of Knowledge And Science Is Irrationalism, Not Religion

We Debase The Richness Of Both Nature And Our Own Minds If We View The Great Pageant Of Our Intellectual History As A Compendium Of New Information Leading From Primal Superstition To Final Exactitude. We Know That The Sun Is Hub Of Our Little Corner Of The Universe, And That Ties Of Genealogy Connect All Living Things On Our Planet, Because These Theories Assemble And Explain So Much Otherwise Disparate And Unrelated Information Not Because Galileo Trained His Telescope On The Moons Of Jupiter Or Because Darwin Took A Ride On A Galápagos Tortoise.

We May Need Simple And Heroic Legends For That Peculiar Genre Of Literature Known As The Textbook. But Historians Must Also Labor To Rescue Human Beings From Their Legends In Science If Only So That We May Understand The Process Of Scientific Thought Aright.

Rifkin's Assertions Bear No Relationship To What I Have Observed And Practiced For 25 Years ... Either I Am Blind Or He Is Wrong - And I Think I Can Show, By Analyzing His Slipshod Scholarship And Basic Misunderstanding Of Science, That His World Is An Invention Constructed To Validate His Own Private Hopes ... Rifkin Shows No Understanding Of The Norms And Procedures Of Science: He Displays Little Comprehension Of What Science Is And How Scientists Work.

The Spirit Of Plato Dies Hard. We Have Been Unable To Escape The Philosophical Tradition That What We Can See And Measure In The World Is Merely The Superficial And Imperfect Representation Of An Underlying Reality.

I Emphatically Do Not Assert The General 'truth' Of This Philosophy Of Punctuational Change. Any Attempt To Support The Exclusive Validity Of Such A Grandiose Notion Would Border On The Nonsensical.

A Lot Of Scientists Hate Writing. Most Scientists Love Being In The Lab And Doing The Work And When The Work Is Done, They Are Finished.

[evolution Is] One Of The Best Documented, Most Compelling And Exciting Concepts In All Of Science.

Humans Arose ... As A Fortuitous And Contingent Outcome Of Thousands Of Linked Events, Any One Of Which Could Have Occurred Differently And Sent History On An Alternative Pathway That Would Not Have Led To Consciousness.

Odd Arrangements And Funny Solutions Are The Proof Of Evolution - Paths That A Sensible God Would Never Tread But That A Natural Process, Constrained By History, Follows Perforce.

A Rare Book At Once Of Great Importance And Wonderful To Read.... Gould Presents A Fascinating Historical Study Of Scientific Racism, Tracing It Through Monogeny And Polygeny, Phrenology , Recapitulation, And Hereditarian Iq Theory. He Stops At Each Point To Illustrate Both The Logical Inconsistencies Of The Theories And The Prejudicially Motivated, Albeit Unintentional, Misuse Of Data In Each Case.... A Major Addition To The Scientific Literature.

Misunderstanding Of Probability May Be The Greatest Of All Impediments To Scientific Literacy.

Objectivity Cannot Be Equated With Mental Blankness; Rather, Objectivity Resides In Recognizing Your Preferences And Then Subjecting Them To Especially Harsh Scrutiny - And Also In A Willingness To Revise Or Abandon Your Theories When The Tests Fail (as They Usually Do).

Science Is All Those Things Which Are Confirmed To Such A Degree That It Would Be Unreasonable To Withhold One's Provisional Consent.

Few Intellectual Tyrannies Can Be More Recalcitrant Than The Truths That Everybody Knows And Nearly No One Can Defend With Any Decent Data (for Who Needs Proof Of Anything So Obvious). And Few Intellectual Activities Can Be More Salutary Than Attempts To Find Out Whether These Rocks Of Ages Might Crumble At The Slightest Tap Of An Informational Hammer.

The Modern Theory Of Evolution Does Not Require Gradual Change. It In Fact, The Operation Of Darwinian Processes Should Yield Exactly What We See In The Fossil Record. It Is Gradualism That We Must Reject, Not Darwinism.

Theory Of Evolution

Science Is An Integral Part Of Culture. It's Not This Foreign Thing, Done By An Arcane Priesthood. It's One Of The Glories Of The Human Intellectual Tradition.

Evolving Life Must Experience A Vast Range Of Possibilities, Based On Environmental Histories So Unpredictable That No Realized Route - The Pathway To Consciousness In The Form Of Homo Sapiens Or Little Green Men, For Example - Can Be Construed As A Highway To Heaven, But Must Be Viewed As A Tortuous Track Rutted With Uncountable Obstacles And Festooned With Innumerable Alternative Branches. Any Reasonably Precise Repetition Of Our Earthly Route On Another Planet Therefore Becomes Wildly Improbable Even In A Trillion Cases.

No One Supposed That Dinoflagellates Might Actively Kill Fish As An Evolved Response For Their Own Specific Advantage, Including A Potential Nutritional Benefit For The Algal Cells. And Yet The Dinoflagellates Do Seem To Be Killing And Eating Fishes In A Manner Suggesting Active Evolution For This Most Peculiar Reversal.

But If We Laugh With Derision, We Will Never Understand. Human Intellectual Capacity Has Not Altered For Thousands Of Years So Far As We Can Tell. If Intelligent People Invested Intense Energy In Issues That Now Seem Foolish To Us, Then The Failure Lies In Our Understanding Of Their World, Not In Their Distorted Perceptions.

Siphonophores Do Not Convey The Message A Favorite Theme Of Unthinking Romanticism That Nature Is But One Gigantic Whole, All Its Parts Intimately Connected And Interacting In Some Higher, Ineffable Harmony. Nature Revels In Boundaries And Distinctions; We Inhabit A Universe Of Structure. But Since Our Universe Of Structure Has Evolved Historically, It Must Present Us With Fuzzy Boundaries, Where One Kind Of Thing Grades Into Another.

The Argument That The Literal Story Of Genesis Can Qualify As Science Collapses On Three Major Grounds: The Creationists' Need To Invoke Miracles In Order To Compress The Events Of The Earth's History Into The Biblical Span Of A Few Thousand Years; Their Unwillingness To Abandon Claims Clearly Disproved, Including The Assertion That All Fossils Are Products Of Noah's Flood; And Their Reliance Upon Distortion, Misquote, Half-quote, And Citation Out Of Context To Characterize The Ideas Of Their Opponents.

Any Decent Writer Writes Because There's Some Deep Internal Need To Keep Learning.

Scientists Have Power By Virtue Of The Respect Commanded By The Discipline... We Live With Poets And Politicians, Preachers And Philosophers. All Have Their Ways Of Knowing, And All Are Valid In Their Proper Domain. The World Is Too Complex And Interesting For One Way To Hold All The Answers.

The Darwinian Revolution Is About Essence. The Darwinian Revolution Is About Who We Are, It's What We're Made Of, It's What Our Life Means Insofar As Science Can Answer That Question.

It Is The Things We Think We Know - Because They Are So Elementary Or Because They Surround Us - That Often Present The Greatest Difficulties When We Are Actually Challenged To Explain Them.

I Am, Somehow, Less Interested In The Weight And Convolutions Of Einstein’s Brain Than In The Near Certainty That People Of Equal Talent Have Lived And Died In Cotton Fields And Sweatshops.

True Majorities, In A Tv-dominated And Anti-intellectual Age, May Need Sound Bites And Flashing Lights And I Am Not Against Supplying Such Lures If They Draw Children Into Even A Transient Concern With Science. But Every Classroom Has One [oliver] Sacks , One [eric] Korn, Or One [jonathan] Miller , Usually A Lonely Child With A Passionate Curiosity About Nature, And A Zeal That Overcomes Pressures For Conformity. Do Not The One In Fifty Deserve Their Institutions As Well Magic Places, Like Cabinet Museums, That Can Spark The Rare Flames Of Genius?

I Dreamed Of Becoming A Scientist, In General, And A Paleontologist, In Particular, Ever Since The Tyrannosaurus Skeleton Awed And Scared Me.

Evolution Is An Obstacle Course Not A Freeway; The Correct Analogue For Long-term Success Is A Distant Punt Receiver Evading Legions Of Would-be Tacklers In An Oddly Zigzagged Path Toward A Goal, Not A Horse Thundering Down The Flat.

Nothing Matches The Holiness And Fascination Of Accurate And Intricate Detail.

People Are Clever, But Almost No One Ever Devises An Optimal Quip Precisely At The Needed Moment. Therefore, Virtually All Great One-liners Are Later Inventions - Words That People Wished They Had Spouted, But Failed To Manufacture At The Truly Opportune Instant.

Human Consciousness Arose But A Minute Before Midnight On The Geological Clock. Yet We Mayflies Try To Bend An Ancient World To Our Purposes, Ignorant Perhaps Of The Messages Buried In Its Long History. Let Us Hope That We Are Still In The Early Morning Of Our April Day.

Biological Determinism Is, In Its Essence, A Theory Of Limits. It Takes The Current Status Of Groups As A Measure Of Where They Should And Must Be ... We Inhabit A World Of Human Differences And Predilections, But The Extrapolation Of These Facts To Theories Of Rigid Limits Is Ideology.

We Live In A Profoundly Nonintellectual Culture, Made All The Worse By A Passive Hedonism Abetted By The Spread Of Wealth And Its Dissipation Into Countless Electronic Devices That Impart The Latest In Entertainment And Supposed Information - All In Short (and Loud) Doses Of "easy Listening".

I Despair Of Persuading People To Drop The Familiar And Comforting Tactic Of Dichotomy. Perhaps, Instead, We Might Expand The Framework Of Debates By Seeking Other Dichotomies More Appropriate Than, Or Simply Different From, The Conventional Divisions. All Dichotomies Are Simplifications, But The Rendition Of A Conflict Along Differing Axes Of Several Orthogonal Dichotomies Might Provide An Amplitude Of Proper Intellectual Space Without Forcing Us To Forgo Our Most Comforting Tool Of Thought.

My Own Field Of Paleontology Has Strongly Challenged The Darwinian Premise That Life's Major Transformations Can Be Explained By Adding Up, Through The Immensity Of Geological Time, The Successive Tiny Changes Produced Generation After Generation By Natural Selection.

How Did Scientists Get Money In The Past? They Were Either Lucky And Independently Wealthy, Like Darwin, Or They Had Patrons, Like Galileo. Universities Or Governments Have Become Patrons Only In The Last Few Generations. Many Of The Great Scientists Of The Past Were In Debt To Their Patrons In The Same Sense That Modern Scientists Are Influenced By What Their Granting Agencies Want.

I Am Willing To Believe That My Unobtainable Sixty Seconds Within A Sponge Or A Flatworm Might Not Reveal Any Mental Acuity That I Would Care To Call Consciousness. But I Am Also Confident [...] That Vultures And Sloths, As Close Evolutionary Relatives With The Same Basic Set Of Organs, Lie On Our Side Of Any Meaningful (and Necessarily Fuzzy) Border And That We Are Therefore Not Mistaken When We Look Them In The Eye And See A Glimmer Of Emotional And Conceptual Affinity.

Pictures Are Not Incidental Frills To A Text; They Are Essences Of Our Distinctive Way Of Knowing.

Organisms [...] Are Directed And Limited By Their Past. They Must Remain Imperfect In Their Form And Function, And To That Extent Unpredictable Since They Are Not Optimal Machines. We Cannot Know Their Future With Certainty, If Only Because A Myriad Of Quirky Functional Shifts Lie Within The Capacity Of Any Feature, However Well Adapted To A Present Role.

Life Shows No Trend To Complexity In The Usual Sense-only An Asymmetrical Expansion Of Diversity Around A Starting Point Constrained To Be Simple.

Nothing Is More Dangerous Than A Dogmatic Worldview - Nothing More Constraining, More Blinding To Innovation, More Destructive Of Openness To Novelty.

But Our Ways Of Learning About The World Are Strongly Influenced By The Social Preconceptions And Biased Modes Of Thinking That Each Scientist Must Apply To Any Problem. The Stereotype Of A Fully Rational And Objective Scientific Method, With Individual Scientists As Logical (and Interchangeable) Robots, Is Self-serving Mythology.

With Copious Evidence Ranging From Plato's Haughtiness To Beethoven's Tirades, We May Conclude That The Most Brilliant People Of History Tend To Be A Prickly Lot.

The Extreme Rarity Of Transitional Forms In The Fossil Record Persists As A Trade Secret Of Paleontology. Evolutionary Trees That Adorn Our Textbooks Have Data Only At The Tips And Nodes Of Their Branches; The Rest Is Inference, However Reasonable, Not The Evidence Of Fossils.

Goethe Died In 1832. As You Know, Goethe Was Very Active In Science. In Fact, He Did Some Very Good Scientific Work In Plant Morphology And Mineralogy. But He Was Quite Bitter At The Way In Which Many Scientists Refused To Grant Him A Hearing Because He Was A Poet And Therefore, They Felt, He Couldn't Be Serious.

Nature Is Objective, And Nature Is Knowable, But We Can Only View Her Through A Glass Darkly And Many Clouds Upon Our Vision Are Of Our Own Making: Social And Cultural Biases, Psychological Preferences, And Mental Limitations (in Universal Modes Of Thought, Not Just Individualized Stupidity).

Always Be Suspicious Of Conclusions That Reinforce Uncritical Hope And Follow Comforting Traditions Of Western Thought.

Evolution Is One Of The Two Or Three Most Primally Fascinating Subjects In All The Sciences.

I Love The Wry Motto Of The Paleontological Society, Meant Both Literally And Figuratively, For Hammers Are The Main Tool Of Our Trade: Frango Ut Patefaciam - I Break In Order To Reveal.

I Believe That We Can Still Have A Genre Of Scientific Books Suitable For And Accessible Alike To Professionals And Interested Laypeople. The Concepts Of Science, In All Their Richness And Ambiguity, Can Be Presented Without Any Compromise, Without Any Simplification Counting As Distortion, In Language Accessible To All Intelligent People. I Hope That This Book Can Be Read With Profit Both In Seminars For Graduate Students And If The Movie Stinks And You Forgot Your Sleeping Pills On The Businessman's Special To Tokyo.

As A Word, Ecology Has Been So Debased By Recent Political Usage That Many People Employ It To Identify Anything Good That Happens Far From Cities And Without Human Interference.

Charles Darwin Viewed The Fossil Record More As An Embarrassment Than As An Aid To His Theory.

Any Human Being Is Really Good At Certain Things. The Problem Is That The Things You're Good At Come Naturally. And Since Most People Are Pretty Modest Instead Of An Arrogant S.o.b. Like Me, What Comes Naturally, You Don't See As A Special Skill. It's Just You. It's What You've Always Done.

The Dogmatist Within Is Always Worse Than The Enemy Without.

We Are The Accidental Result Of An Unplanned Process ... The Fragile Result Of An Enormous Concatenation Of Improbabilities, Not The Predictable Product Of Any Definite Process.

Paleontologists [fossil Experts] Have Paid An Exorbitant Price For Darwin's Argument. We Fancy Ourselves As The Only True Students Of Life's History, Yet To Preserve Our Favored Account Of Evolution By Natural Selection We View Our Data As So Bad That We Almost Never See The Very Process We Profess To Study.

Look In The Mirror, And Don't Be Tempted To Equate Transient Domination With Either Intrinsic Superiority Or Prospects For Extended Survival.

Before Kuhn, Most Scientists Followed The Place-a-stone-in-the-bright-temple-of-knowledge Tradition, And Would Have Told You That They Hoped, Above All, To Lay Many Of The Bricks, Perhaps Even The Keystone, Of Truth's Temple. Now Most Scientists Of Vision Hope To Foment Revolution. We Are, Therefore, Awash In Revolutions, Most Self-proclaimed.

We Should Take Comfort In Two Conjoined Features Of Nature: First, That Our World Is Incredibly Strange And Therefore Supremely Fascinating, Second, That However Bizarre And Arcane Our World Might Be, Nature Remains Potentially Comprehensible To The Human Mind.

We Must [it Has Been Arued] Go Beyond Reductionism To A Holistic Recognition That Biology And Culture Interpenetrate In An Inextricable Manner.

Facts And Theories Are Different Things, Not Rungs In A Hierarchy Of Increasing Certainty. Facts Are The World's Data. Theories Are Structures Of Ideas That Explain And Interpret Facts. Facts Do Not Go Away While Scientists Debate Rival Theories For Explaining Them. Einstein's Theory Of Gravitation Replaced Newton's, But Apples Did Not Suspend Themselves In Mid-air Pending The Outcome.

Heydrich, Eichmann, And Company Therefore Invoke The Usual Trick Of Argument For Breaking A True Continuum That Lacks A Compelling Point For Separation: Choose An Arbitrary Dividing Line And Then Treat It As A Self-evident Law Of Nature.

I Am Particularly Fond Of [emmanuel Mendes Da Costa's] Natural History Of Fossils Because This Treatise, More Than Any Other Work Written In English, Records A Short Episode Expressing One Of The Grand False Starts In The History Of Natural Science And Nothing Can Be Quite So Informative And Instructive As A Juicy Mistake.

God Was There When It Happened. We Were Not There.... Therefore, We Are Completely Limited To What God Has Seen Fit To Tell Us, And This Information Is In His Written Word.

We Are Storytelling Animals, And Cannot Bear To Acknowledge The Ordinariness Of Our Daily Lives.

Why, Then, Do I Continue To Claim That Creationism Isn't Science? Simply Because These Relatively Few Statements Have Been Tested And Conclusively Refuted.

Results Rarely Specify Their Causes Unambiguously. If We Have No Direct Evidence Of Fossils Or Human Chronicles, If We Are Forced To Infer A Process Only From Its Modern Results, Then We Are Usually Stymied Or Reduced To Speculation About Probabilities. For Many Roads Lead To Almost Any Rome.

[in Natural History,] Great Discovery Often Requires A Map To A Hidden Mine Filled With Gems Then Easily Gathered By Conventional Tools, Not A Shiny New Space-age Machine For Penetrating Previously Inaccessible Worlds.

Creation Science Has Not Entered The Curriculum For A Reason So Simple And So Basic That We Often Forget To Mention It: Because It Is False, And Because Good Teachers Understand Why It Is False. What Could Be More Destructive Of That Most Fragile Yet Most Precious Commodity In Our Entire Intellectual Heritage-good Teaching-than A Bill Forcing Our Honorable Teachers To Sully Their Sacred Trust By Granting Equal Treatment To A Doctrine Not Only Known To Be False, But Calculated To Undermine Any General Understanding Of Science As An Enterprise?.

I Am Glad That The Life Of Pandas Is So Dull By Human Standards, For Our Efforts At Conservation Have Little Moral Value If We Preserve Creatures Only As Human Ornaments; I Shall Be Impressed When We Show Solicitude For Warty Toads And Slithering Worms.

Something Deep Within Us Drives Accurate Messiness Into The Neat Channels Of Canonical Stories.

Transitional Forms Are Generally Lacking At The Species Level, But They Are Abundant Between Larger Groups.

Knowledge And Wonder Are The Dyad Of Our Worthy Lives As Intellectual Beings. Voyager Did Wonders For Our Knowledge, But Performed Just As Mightily In The Service Of Wonder And The Two Elements Are Complementary, Not Independent Or Opposed. The Thought Fills Me With Awe - A Mechanical Contraption That Could Fit In The Back Of A Pickup Truck, Traveling Through Space For Twelve Years, Dodging Around Four Giant Bodies And Their Associated Moons, And Finally Sending Exquisite Photos Across More Than Four Light-hours Of Space From The Farthest Planet In Our Solar System.

Creationist Critics Often Charge That Evolution Cannot Be Tested, And Therefore Cannot Be Viewed As A Properly Scientific Subject At All. This Claim Is Rhetorical Nonsense.

We Must Shed The Old Stereotype Of Anarchists As Bearded Bomb Throwers Furtively Stalking About City Streets At Night.

The Intricate And Different Life Cycles Of Both Male And Female Root-heads, And The Great Behavioral Sophistication Shown By The Female In Reconfiguring A Host Crab As A Support System, All Underscore The Myopia Of Our Conventional Wisdom In Regarding Rhizocephalans As Degenerate Parasites Because The Adult Anatomy Of Internal Roots And External Sac Seem So Simple.

Support Systems

If Genius Has Any Common Denominator, I Would Propose Breadth Of Interest And The Ability To Construct Fruitful Analogies Between Fields.

I Would Rather Label The Whole Enterprise Of Setting A Biological Value Upon Groups For What It Is: Irrelevant, Intellectually Unsound, And Highly Injurious.

Perhaps Randomness Is Not Merely An Adequate Description For Complex Causes That We Cannot Specify. Perhaps The World Really Works This Way, And Many Events Are Uncaused In Any Conventional Sense Of The Word. Perhaps Our Gut Feeling That It Cannot Be So Reflects Only Our Hopes And Prejudices, Our Desperate Striving To Make Sense Of A Complex And Confusing World, And Not The Ways Of Nature.

The Legends Of Fieldwork Locate All Important Sites Deep In Inaccessible Jungles Inhabited By Fierce Beasts And Restless Natives, And Surrounded By Miasmas Of Putrefaction And Swarms Of Tsetse Flies.

Even The Standard Example Of Ancient Nonsense - The Debate About Angels On Pinheads - Makes Sense Once You Realize That Theologians Were Not Discussing Whether Five Or Eighteen Would Fit, But Whether A Pin Could House A Finite Or An Infinite Number.

Memory Is A Fascinating Trickster. Words And Images Have Enormous Power And Can Easily Displace Actual Experience Over The Years.

Contrary To Current Cynicism About Past Golden Ages, The Abstraction Known As 'the Intelligent Layperson' Does Exist - In The Form Of Millions Of Folks With A Passionate Commitment To Continuous Learning.

If You Defend A Behavior By Arguing That People Are Programmed Directly For It, Then How Do You Continue To Defend It If Your Speculation Is Wrong, For The Behavior Then Becomes Unnatural And Worthy Of Condemnation. Better To Stick Resolutely To A Philosophical Position On Human Liberty: What Free Adults Do With Each Other In Their Own Private Lives Is Their Business Alone. It Need Not Be Vindicated And Must Not Be Condemned By Genetic Speculation.

The Myriad Valleys Could Have Arisen Anywhere On The Landscape. The Current Positions Are Quite Accidental. If We Could Repeat The Experiment, We Might Obtain No Valleys At All, Or A Completely Different System. Yet We Now Stand At The Shore Line Contemplating The Fine Spacing Of Valleys And Their Even Contact With The Sea. How Easy It Is To Be Misled And To Assume That No Other Landscape Could Possibly Have Arisen.

All Organisms Vary, And It's Just Folk Knowledge. You Just Have To Look Around A Room Of People, And Everybody Knows That It's True. Darwin Didn't Know The Mechanism Of Heredity, But You Don't Have To. You Just Need To Know The Fact Of It.

An Old Paleontological In Joke Proclaims That Mammalian Evolution Is A Tale Told By Teeth Mating To Produce Slightly Altered Descendant Teeth.

Natural Selection Is A Theory Of Local Adaptation To Changing Environments. It Proposes No Perfecting Principles, No Guarantee Of General Improvement

Changing Environment

The Pathways That Have Led To Our Evolution Are Quirky, Improbable, Unrepeatable And Utterly Unpredictable.

South America Had Been An Island Continent, Far Bigger And Far More Diverse Than Australia, For Tens Of Millions Of Years Before The Isthmus Of Panama Rose Just A Couple Of Million Years Ago. The Resulting Flood Of North American Mammals Across The New Land Bridge Corresponds In Time With The Decimation Of The Native South American Fauna. In Fact, Most Large Mammals Generally Considered Distinctly South American... Are All Recent Migrants From North America.

Evolution Is A Process Of Constant Branching And Expansion.

No Geologist Worth Anything Is Permanently Bound To A Desk Or Laboratory, But The Charming Notion That True Science Can Only Be Based On Unbiased Observation Of Nature In The Raw Is Mythology. Creative Work, In Geology And Anywhere Else, Is Interaction And Synthesis: Half-baked Ideas From A Bar Room, Rocks In The Field, Chains Of Thought From Lonely Walks, Numbers Squeezed From Rocks In A Laboratory, Numbers From A Calculator Riveted To A Desk, Fancy Equipment Usually Malfunctioning On Expensive Ships, Cheap Equipment In The Human Cranium, Arguments Before A Road Cut.

As A Graduate Student At Columbia University, I Remember The A Priori Derision Of My Distinguished Stratigraphy Professor Toward A Visiting Australian Drifter [a Supporter Of The Theory Of Continental Drift]. Today My Own Students Would Dismiss With Even More Derision Anyone Who Denied The Evident Truth Of Continental Drift - A Prophetic Madman Is At Least Amusing; A Superannuated Fuddy-duddy Is Merely Pitiful.

... Many Folks Take Them Seriously Because They Just 'know' That Evolution Can Never Be Seen In The Immediate Here And Now. In Fact, A Precisely Opposite Situation Prevails: Biologists Have Documented A Veritable Glut Of Cases For Rapid And Eminently Measurable Evolution On Timescales Of Years And Decades.

Fundamentalism Is Rigorously And Systematically Used To Indoctrinate And Subjugate Young Minds. It Is A Contraceptive Designed To Prevent Intellectual Fertilization.

A Complete Theory Of Evolution Must Acknowledge A Balance Between "external" Forces Of Environment Imposing Selection For Local Adaptation And "internal" Forces Representing Constraints Of Inheritance And Development. Vavilov Placed Too Much Emphasis On Internal Constraints And Downgraded The Power Of Selection. But Western Darwinians Have Erred Equally In Practically Ignoring (while Acknowledging In Theory) The Limits Placed On Selection By Structure And Development What Vavilov And The Older Biologists Would Have Called "laws Of Form.

Theory Of Evolution

Natural Selection May Lead To Benefits For Species, But These `higher' Advantages Can Only Arise As Sequelae, Or Side Consequences, Of Natural Selection's Causal Mechanism: Differential Reproductive Success Of Individuals.

The Enemy Is Not Fundamentalism; It Is Intolerance. In This Case, The Intolerance Is Perverse Since It Masquerades Under The "liberal" Rhetoric Of "equal Time." But Mistake It Not.

Throughout His Last Half-dozen Books, For Example, Arthur Koestler Has Been Conducting A Campaign Against His Own Misunderstanding Of Darwinism. He Hopes To Find Some Ordering Force, Constraining Evolution To Certain Directions And Overriding The Influence Of Natural Selection. [...] Darwinism Is Not The Theory Of Capricious Change That Koestler Imagines. Random Variation May Be The Raw Material Of Change, But Natural Selection Builds Good Design By Rejecting Most Variants While Accepting And Accumulating The Few That Improve Adaptation To Local Environments.

The Oppressive Weight Of Disaster And Tragedy In Our Lives Does Not Arise From A High Percentage Of Evil Among The Summed Total Of All Acts, But From The Extraordinary Power Of Exceedingly Rare Incidents Of Depravity To Inflict Catastrophic Damage, Especially In Our Technological Age When Airplanes Can Become Powerful Bombs. (an Even More Evil Man, Armed Only With A Longbow, Could Not Have Wreaked Such Havoc At The Battle Of Agincourt In 1415.)

Good Scholars Struggle To Understand The World In An Integral Way (pedants Bite Off Tiny Bits And Worry Them To Death). These Visions Of Reality [...] Demand Our Respect, For They Are An Intellectual's Only Birthright. They Are Often Entirely Wrong And Always Flawed In Serious Ways, But They Must Be Understood Honorably And Not Subjected To Mayhem By The Excision Of Patches.

The Essence Of Darwinism Lies In Its Claim That Natural Selection Creates The Fit. Variation Is Ubiquitous And Random In Direction. It Supplies Raw Material Only. Natural Selection Directs The Course Of Evolutionary Change.

Human Life Is The Result Of A Glorious Evolutionary Accident.

The Invalid Assumption That Correlation Implies Cause Is Probably Among The Two Or Three Most Serious And Common Errors Of Human Reasoning.

The Literal Record Was Not A Hopelessly And Imperfect Fraction Of Truly Insensible Gradation Within Large Populations But An Accurate Reflection Of The Actual Process Identified By Evolutionists As The Chief Motor Of Biological Change. The Theory Of Punctuated Equilibrium Was, In Its Initial Formulation, Little More Than This Insight Adumbrated.

The Great Merit Of Stephen Gould's Account Of The Disastrous History Of Phychometrics Is That He Shifts The Argument From A Sterile Contest Between Environmentalists And Hereditarians And Turns It Into An Argument Between Those Who Are Impressed With What Our Biology Stops Us Doing And Those Who Are Impressed With What It Allows Us To Do.

We Have Become, By The Power Of A Glorious Evolutionary Accident Called Intelligence, The Stewards Of Life's Continuity On Earth. We Did Not Ask For This Role, But We Cannot Abjure It. We May Not Be Suited To It, But Here We Are.

Taxonomy (the Science Of Classification) Is Often Undervalued As A Glorified Form Of Filing-with Each Species In Its Folder, Like A Stamp In Its Prescribed Place In An Album; But Taxonomy Is A Fundamental And Dynamic Science, Dedicated To Exploring The Causes Of Relationships And Similarities Among Organisms. Classifications Are Theories About The Basis Of Natural Order, Not Dull Catalogues Compiled Only To Avoid Chaos.

A Man Does Not Attain The Status Of Galileo Merely Because He Is Persecuted; He Must Also Be Right.

The More Important The Subject And The Closer It Cuts To The Bone Of Our Hopes And Needs, The More We Are Likely To Err In Establishing A Framework For Analysis.

It Seems The Height Of Antiquated Hubris To Claim That The Universe Carried On As It Did For Billions Of Years In Order To Form A Comfortable Abode For Us. Chance And Historical Contingency Give The World Of Life Most Of Its Glory And Fascination. I Sit Here Happy To Be Alive And Sure That Some Reason Must Exist For "why Me?" Or The Earth Might Have Been Totally Covered With Water, And An Octopus Might Now Be Telling Its Children Why The Eight-legged God Of All Things Had Made Such A Perfect World For Cephalopods.

Evolution Has Encountered No Intellectual Trouble; No New Arguments Have Been Offered. Creationism Is A Home-grown Phenomenon Of American Sociocultural History-a Splinter Movement ... Who Believe That Every Word In The Bible Must Be Literally True, Whatever Such A Claim Might Mean.

I Don't Think Academic Writing Ever Was Wonderful. However, Science Used To Be Much Less Specialized.

At A Minimum, In Explaining Evolutionary Pathways Through Time, The Constraints Imposed By History Rise To Equal Prominence With The Immediate Advantages Of Adaptation.

The World Is Too Complex For Subsumption Under Any General Theory Of Change.

The Origin Of Homo Sapiens, As A Tiny Twig On An Improbable Branch Of A Contingent Limb On A Fortunate Tree, Lies Well Below The Boundary.

It Has Become, In My View, A Bit Too Trendy To Regard The Acceptance Of Death As Something Tantamount To Intrinsic Dignity. Of Course I Agree With The Preacher Of Ecclesiastes That There Is A Time To Love And A Time To Die - And When My Skein Runs Out I Hope To Face The End Calmly And In My Own Way. For Most Situations, However, I Prefer The More Martial View That Death Is The Ultimate Enemy - And I Find Nothing Reproachable In Those Who Rage Mightily Against The Dying Of The Light.

Sure We Fit. We Wouldn't Be Here If We Didn't. But The World Wasn't Made For Us And It Will Endure Without Us.

Since We Proposed Punctuated Equilibria To Explain Trends, It Is Infuriating To Be Quoted Again And Again By Creationists-whether Through Design Or Stupidity, I Do Not Know-as Admitting That The Fossil Record Includes No Transitional Forms. Transitional Forms Are Generally Lacking At The Species Level, But They Are Abundant Between Larger Groups.

Most Impediments To Scientific Understanding Are Conceptual Locks, Not Factual Lacks. Most Difficult To Dislodge Are Those Biases That Escape Our Scrutiny Because They Seem So Obviously, Even Ineluctably, Just. We Know Ourselves Best And Tend To View Other Creatures As Mirrors Of Our Own Constitution And Social Arrangements. ( Aristotle , And Nearly Two Millennia Of Successors, Designated The Large Bee That Leads The Swarm As A King.

Advocates For A Single Line Of Progress Encounter Their Greatest Stumbling Block When They Try To Find A Smooth Link Between The Apparently Disparate Designs Of The Invertebrates And Vertebrates.

Mass Extinctions May Not Threaten Distant Futures, But They Are Decidedly Unpleasant For Species Caught Up In The Throes Of Their Power.

Mass Extinction

The Spandrels Of San Marco And The Panglossian Paradigm.

All Science Is Intelligent Inference; Excessive Literalism Is Delusion, Not A Humble Bowing To Evidence.

Skepticism Is The Agent Of Reason Against Organized Irrationalism--and Is Therefore One Of The Keys To Human Social And Civic Decency.

Orchids Manufacture Their Intricate Devices From The Common Components Of Ordinary Flowers, Parts Usually Fitted For Very Different Functions. If God Had Designed A Beautiful Machine To Reflect His Wisdom And Power, Surely He Would Not Have Used A Collection Of Parts Generally Fashioned For Other Purposes. Orchids Were Not Made By An Ideal Engineer; They Are Jury-rigged From A Limited Set Of Available Components. Thus, They Must Have Evolved From Ordinary Flowers.

[g]enes Make Enzymes, And Enzymes Control The Rates Of Chemical Processes. Genes Do Not Make "novelty Seeking" Or Any Other Complex And Overt Behavior. Predisposition Via A Long Chain Of Complex Chemical Reactions, Mediated Through A More Complex Series Of Life's Circumstances, Does Not Equal Identification Or Even Causation.

Acquired Characteristics Are Inherited In Technology And Culture. Lamarckian Evolution Is Rapid And Accumulative. It Explains The Cardinal Difference Between Our Past, Purely Biological Mode Of Change, And Our Current, Maddening Acceleration Toward Something New And Liberating- Or Toward The Abyss.

Hyper-selectionism Has Been With Us For A Long Time In Various Guises; For It Represents The Late Nineteenth Century's Scientific Version Of The Myth Of Natural Harmony All Is For The Best In The Best Of All Possible Worlds (all Structures Well Designed For A Definite Purpose In This Case). It Is, Indeed, The Vision Of Foolish Dr. Pangloss, So Vividly Satirized By Voltaire In Candide The World Is Not Necessarily Good, But It Is The Best We Could Possibly Have.

Our Creationist Detractors Charge That Evolution Is An Unproved And Unprovable Charade — A Secular Religion Masquerading As Science. They Claim, Above All, That Evolution Generates No Predictions, Never Exposes Itself To Test, And Therefore Stands As Dogma Rather Than Disprovable Science. This Claim Is Nonsense.

Organisms Are Not Billiard Balls, Propelled By Simple And Measurable External Forces To Predictable New Positions On Life's Pool Table. Sufficiently Complex Systems Have Greater Richness. Organisms Have A History That Constrains Their Future In Myriad, Subtle Ways.

Words Change Their Meanings, Just As Organisms Evolve. We Would Impose An Enormous Burden On Our Economy If We Insisted On Payment In Cattle Every Time We Identified A Bonus As A Pecuniary Advantage (from The Latin Pecus , Or Cattle, A Verbal Fossil From A Former Commercial Reality).

What You See Is That The Most Outstanding Feature Of Life's History Is A Constant Domination By Bacteria.

Zoocentrism Is The Primary Fallacy Of Human Sociobiology, For This View Of Human Behavior Rests On The Argument That If The Actions Of "lower" Animals With Simple Nervous Systems Arise As Genetic Products Of Natural Selection, Then Human Behavior Should Have A Similar Basis.

[e]volutionists Sometimes Take As Haughty An Attitude Toward The Next Level Up The Conventional Ladder Of Disciplines: The Human Sciences. They Decry The Supposed Atheoretical Particularism Of Their Anthropological Colleagues And Argue That All Would Be Well If Only The Students Of Humanity Regarded Their Subject As Yet Another Animal And Therefore Yielded Explanatory Control To Evolutionary Biologists.

Natural Selection Is Just Three Factors - Over-production, Variation, And Inheritance Combined To Produce Adaptation To Changing Local Environments. It's Not A Principle Or Progress; It's Just A Principle Of Local Adaptation. You Don't Make Better Creatures In Any Cosmic Sense; You Make Creatures That Are Better Suited To The Changing Climates Of Their Local Habitats.

Unfortunately, All Life On Earth - The Only Life We Know - Represents, For All Its Current Variety, The Results Of A Single Experiment , For Every Earthly Species Evolved From The Common Ancestry Of A Single Origin. We Desperately Need A Repetition Of The Experiment (several Would Be Better, But Let's Not Be Greedy!) In Order To Make A Judgement. Mars Represents Our First Real Hope For A Second Experiment - The Sine Qua Non - For Any Proper Answer For The Question Of Questions.

... Each With Its Own Beauty, And Each With A Story To Tell.

Humans Are Not The End Result Of Predictable Evolutionary Progress, But Rather A Fortuitous Cosmic Afterthought, A Tiny Little Twig On The Enormously Arborescent Bush Of Life, Which If Replanted From Seed, Would Almost Surely Not Grow This Twig Again.

History Does Include Aspects Of Directionality, And The Present Range Of Causes And Phenomena Does Not Exhaust The Realm Of Past Possibilities.

Some Beliefs May Be Subject To Such Instant, Brutal And Unambiguous Rejection. For Example: No Left-coiling Periwinkle Has Ever Been Found Among Millions Of Snails Examined. If I Happen To Find One During My Walk On Nobska Beach Tomorrow Morning, A Century Of Well Nurtured Negative Evidence Will Collapse In An Instant.

If I Have Any Insight At All To Contribute It Is This: Find Out What You Are Really Good At And Stick To It.

The Human Brain Became Large By Natural Selection (who Knows Why, But Presumably For Good Cause). Yet Surely Most "things" Now Done By Our Brains, And Essential Both To Our Cultures And To Our Very Survival, Are Epiphenomena Of The Computing Power Of This Machine, Not Genetically Grounded Darwinian Entities Created Specifically By Natural Selection For Their Current Function.

Life Is A Copiously Branching Bush, Continually Pruned By The Grim Reaper Of Extinction, Not A Ladder Of Predictable Progress.

Our World Is Not An Optimal Place, Fine Tuned By Omnipotent Forces Of Selection. It Is A Quirky Mass Of Imperfections, Working Well Enough (often Admirably); A Jury-rigged Set Of Adaptations Built Of Curious Parts Made Available By Past Histories In Different Contexts. A World Optimally Adapted To Current Environments Is A World Without History, And A World Without History Might Have Been Created As We Find It. History Matters; It Confounds Perfection And Proves That Current Life Transformed Its Own Past.

The True Beauty Of Nature Is Her Amplitude; She Exists Neither For Nor Because Of Us, And Possesses A Staying Power That All Our Nuclear Arsenals Cannot Threaten (much As We Can Easily Destroy Our Puny Selves).

Death Is The Ultimate Enemy - And I Find Nothing Reproachable In Those Who Rage Mightily Against The Dying Of The Light.

When We Seek A Textbook Case For The Proper Operation Of Science, The Correction Of Certain Error Offers Far More Promise Than The Establishment Of Probable Truth. Confirmed Hunches, Of Course, Are More Upbeat Than Discredited Hypotheses. Since The Worst Traditions Of "popular" Writing Falsely Equate Instruction With Sweetness And Light, Our Promotional Literature Abounds With Insipid Tales In The Heroic Mode, Although Tough Stories Of Disappointment And Loss Give Deeper Insight Into A Methodology That The Celebrated Philosopher Karl Popper Once Labeled As "conjecture And Refutation.

The Median Isn't The Message.

The Proof Of Evolution Lies In Those Adaptations That Arise From Improbable Foundations.

Great Theories Are Expansive; Failures Mire Us In Dogmatism And Tunnel Vision.

[t]ruly Grand And Powerful Theories [...] Do Not And Cannot Rest Upon Single Observations. Evolution Is An Inference From Thousands Of Independent Sources, The Only Conceptual Structure That Can Make Unified Sense Of All This Disparate Information. The Failure Of A Particular Claim Usually Records A Local Error, Not The Bankruptcy Of A Central Theory. [...] If I Mistakenly Identify Your Father's Brother As Your Own Dad, You Don't Become Genealogically Rootless And Created De Novo. You Still Have A Father; We Just Haven't Located Him Properly.

When We Look To Presumed Sources Of Origin For Competing Evolutionary Explanations Of The Giraffe's Long Neck, We Find Either Nothing At All, Or Only The Shortest Of Speculative Conjectures. Length, Of Course, Need Not Correspond With Importance. Garrulous Old Polonius , In A Rare Moment Of Clarity, Reminded Us That "brevity Is The Soul Of Wit" (and Then Immediately Vitiated His Wise Observation With A Flood Of Woolly Words About Hamlet 's Madness.

The Real Tragedy Of Human Existence Is Not That We Are Nasty By Nature, But That A Cruel Structural Asymmetry Grants To Rare Events Of Meanness Such Power To Shape Our History.

World Views Are Social Constructions And They Channel The Search For Facts. But Facts Are Found And Knowledge Progresses, However Fitfully.

The Center Of Human Nature Is Rooted In Ten Thousand Ordinary Acts Of Kindness That Define Our Days.

You Put Three Facts Together - That All Organisms Produce More Offspring That Can Survive, That There's Variation Among Organisms, And That At Least Some Of That Variation Is Inherited - And The Syllogistic Inference Is Natural Selection.
