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.

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.

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.

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

I Am Not [...] Asserting That Humans Are Either Genial Or Aggressive By Inborn Biological Necessity. Obviously, Both Kindness And Violence Lie Within The Bounds Of Our Nature Because We Perpetrate Both, In Spades. I Only Advance A Structural Claim That Social Stability Rules Nearly All The Time And Must Be Based On An Overwhelmingly Predominant (but Tragically Ignored) Frequency Of Genial Acts, And That Geniality Is Therefore Our Usual And Preferred Response Nearly All The Time. [...] [t]he Center Of Human Nature Is Rooted In Ten Thousand Ordinary Acts Of Kindness That Define Our Days.

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.

If We Choose A Weak And Foolish Speculation As A Primary Textbook Illustration (falsely Assuming That The Tale Possesses A Weight Of History And A Sanction Of Evidence), Then We Are In For Trouble - As Critics Properly Nail The Particular Weakness, And Then Assume That The Whole Theory Must Be In Danger If Supporters Choose Such A Fatuous Case As A Primary Illustration.

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.

The Dogmatist Within Is Always Worse Than The Enemy Without.

I Have Often Been Amused By Our Vulgar Tendency To Take Complex Issues, With Solutions At Neither Extreme Of A Continuum Of Possibilities, And Break Them Into Dichotomies, Assigning One Group To One Pole And The Other To An Opposite End, With No Acknowledgment Of Subtleties And Intermediate Positions And Nearly Always With Moral Opprobrium Attached To Opponents.

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

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.

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).

I Am Not, Personally, A Believer Or A Religious Man In Any Sense Of Institutional Commitment Or Practice. But I Have A Great Respect For Religion, And The Subject Has Always Fascinated Me, Beyond Almost All Others (with A Few Exceptions, Like Evolution And Paleontology).

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.

Precise Adaptation, With Each Part Finely Honed To Perform A Definite Function In An Optimal Way, Can Only Lead To Blind Alleys, Dead Ends, And Extinction.

Contingency Is Rich And Fascinating; It Embodies An Exquisite Tension Between The Power Of Individuals To Modify History And The Intelligible Limits Set By Laws Of Nature. The Details Of Individual And Species's Lives Are Not Mere Frills, Without Power To Shape The Large-scale Course Of Events, But Particulars That Can Alter Entire Futures, Profoundly And Forever.

The Vigorous Branching Of Life's Tree, And Not The Accumulating Valor Of Mythical Marches To Progress, Lies Behind The Persistence And Expansion Of Organic Diversity In Our Tough And Constantly Stressful World. And If We Do Not Grasp The Fundamental Nature Of Branching As The Key To Life's Passage Across The Geological Stage, We Will Never Understand Evolution Aright.

But We All Recognise The Primary Foible Of Frail Humanity - Our Propensity For Embracing Hope And Shunning Logic, Our Tendency To Believe What We Desire Rather Than What We Observe.

We Are Glorious Accidents Of An Unpredictable Process With No Drive To Complexity, Not The Expected Results Of Evolutionary Principles That Yearn To Produce A Creature Capable Of Understanding The Mode Of Its Own Necessary Construction.

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

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?

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

Nothing Is More Dangerous Than A Dogmatic Worldview.

What's Important Is That All Human Knowledge Be Made Available To All Intelligent People Who Want To Learn It.

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.

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.

The Theory Of Punctuated Equilibrium, Proposed By Niles Eldredge And Myself, Is Not, As So Often Misunderstood, A Radical Claim For Truly Sudden Change, But A Recognition That Ordinary Processes Of Speciation, Properly Conceived As Glacially Slow By The Standard Of Our Own Life-span, Do Not Resolve Into Geological Time As Long Sequences Of Insensibly Graded Intermediates (the Traditional, Or Gradualistic, View), But As Geologically "sudden" Origins At Single Bedding Planes.

... No Compelling Data To Support Its Anachronistic Social Darwinism.

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

We Cannot Win This Battle To Save Species And Environments Without Forging An Emotional Bond Between Ourselves And Nature As Well - For We Will Not Fight To Save What We Do Not Love.

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

Sigmund Freud Often Remarked That Great Revolutions In The History Of Science Have But One Common, And Ironic, Feature: They Knock Human Arrogance Off One Pedestal After Another Of Our Previous Conviction About Our Own Self-importance.

Iconography Becomes Even More Revealing When Processes Or Concepts, Rather Than Objects, Must Be Depicted For The Constraint Of A Definite "thing" Cedes Directly To The Imagination. How Can We Draw "evolution" Or "social Organization," Not To Mention The More Mundane "digestion" Or "self-interest," Without Portraying More Of A Mental Structure Than A Physical Reality? If We Wish To Trace The History Of Ideas, Iconography Becomes A Candid Camera Trained Upon The Scholar's Mind.

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.

I Strongly Reject Any Conceptual Scheme That Places Our Options On A Line, And Holds That The Only Alternative To A Pair Of Extreme Positions Lies Somewhere Between Them. More Fruitful Perspectives Often Require That We Step Off The Line To A Site Outside The Dichotomy.

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 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.

Not Since The Lord Himself Showed His Stuff To Ezekiel In The Valley Of Dry Bones Had Anyone Brought Such Grace And Skill To The Reconstruction Of Animals From Disarticulated Skeletons. Charles R. Knight, Most Celebrated Of Artists In The Reanimation Of Fossils, Painted All The Canonical Figures Of Dinosaurs That Fire Our Fear And Imagination To This Day.

I Love To Read The Dedications Of Old Books Written In Monarchies For They Invariably Honor Some (usually Insignificant) Knight Or Duke With Fulsome Words Of Sycophantic Insincerity, Praising Him As The Light Of The Universe (in Hopes, No Doubt, For A Few Ducats To Support Future Work); This Old Practice Makes Me Feel Like Such An Honest And Upright Man, By Comparison, When I Put A Positive Spin, Perhaps Ever So Slightly Exaggerated, On A Grant Proposal.

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.

We Build Our Personalities Laboriously And Through Many Years, And We Cannot Order Fundamental Changes Just Because We Might Value Their Utility; No Button Reading "positive Attitude" Protrudes From Our Hearts, And No Finger Can Coerce Positivity Into Immediate Action By A Single And Painless Pressing.

In Science, 'fact' Can Only Mean 'confirmed To Such A Degree That It Would Be Perverse To Withhold Provisional Assent.' I Suppose That Apples Might Start To Rise Tomorrow, But The Possibility Does Not Merit Equal Time In Physics Classrooms.

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.

Human Life Is The Result Of A Glorious Evolutionary Accident.

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.

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

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

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.

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).

The Truly Awesome Intellectuals In Our History Have Not Merely Made Discoveries; They Have Woven Variegated, But Firm, Tapestries Of Comprehensive Coverage. The Tapestries Have Various Fates: Most Burn Or Unravel In The Footsteps Of Time And The Fires Of Later Discovery. But Their Glory Lies In Their Integrity As Unified Structures Of Great Complexity And Broad Implication.

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

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, A Tiny Little Twig On The Enormously Arborescent Bush Of Life, Which, If Replanted From Seed, Would Almost Surely Not Grow This Twig Again, Or Perhaps Any Twig With Any Property That We Would Care To Call Consciousness.

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.

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.

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

Changing Environment

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

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.

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.

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

Science Is Not 'organized Common Sense'; At Its Most Exciting, It Reformulates Our View Of The World By Imposing Powerful Theories Against The Ancient, Anthropocentric Prejudices That We Call Intuition.

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.

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).

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

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.

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

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.

I'm Not A Great Deductive Thinker, But I Will Admit To Having Competence In A Very Wide Range Of Things - Not Being Afraid To Try To Write About Baseball, Choral Music And Dinosaurs In The Same Week And See Connections Among Them.

The Most Erroneous Stories Are Those We Think We Know Best - And Therefore Never Scrutinize Or Question.

In The Great Debates Of Early-nineteenth Century Geology, Catastrophists Followed The Stereotypical Method Of Objective Science-empirical Literalism. They Believed What They Saw, Interpolated Nothing, And Read The Record Of The Rocks Directly.

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.

[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.

The Equation Of Evolution With Progress Represents Our Strongest Cultural Impediment To A Proper Understanding Of This Greatest Biological Revolution In The History Of Human Thought.

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

No One Should Feel At All Offended Or Threatened By The Obvious Fact That We Are Not All Born Entirely Blank, Or Entirely The Same, In Our Mixture Of The Broad Behavioral Propensities Defining What We Call "temperament".

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.

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

Current Utility And Historical Origin Are Different Subjects.

The Most Important Scientific Revolutions All Include, As Their Only Common Feature, The Dethronement Of Human Arrogance From One Pedestal After Another Of Previous Convictions About Our Centrality In The Cosmos.

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

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.

... 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.

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.

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.

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.

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.

Mary Anning [is] Probably The Most Important Unsung (or Inadequately Sung) Collecting Force In The History Of Paleontology.

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.

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

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

People May Believe Correct Things For The Damndest And Weirdest Of Wrong Reasons.

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.

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.

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.

Science Simply Cannot Adjudicate The Issue Of God's Possible Superintendence Of Nature.

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.

Science Can't Tell Us What Our Life Means Ethically. It Can't Tell Us What We Are Meant To Do As Moral Creatures. But, Insofar As Science Can Understand What We're Made Of, And What We're Related To, The Darwinian Revolution Completely Revised Our Ideas About Who We Are And What We're Related To And How Long We've Been Here And Why We're On This Earth.

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.

I Would Trade All The Advantages Of Humanity To Be A Fly On The Wall When Franklin And Jefferson Discussed Liberty, Lenin And Trotsky Revolution, Newton And Halley The Shape Of The Universe, Or When Darwin Entertained Huxley And Lyell At Down.

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.

Change Is More Often A Rapid Transition Between Two Stable States Than A Continuous Transformation At Slow And Steady Rates. . . .change Occurs In Large Leaps Following A Slow Accumulation Of Stress That A System Resists Until It Reaches The Breaking Point. Heat Water, And It Eventually Boils. Oppress The Workers More And More And Bring On The Revolution.

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.

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.

As We Discern A Fine Line Between Crank And Genius, So Also (and Unfortunately) We Must Acknowledge An Equally Graded Trajectory From Crank To Demagogue. When People Learn No Tools Of Judgment And Merely Follow Their Hopes, The Seeds Of Political Manipulation Are Sown.

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.

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

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.

There Is No Gene "for" Such Unambiguous Bits Of Morphology As Your Left Kneecap Or Your Fingernail. [...] Hundreds Of Genes Contribute To The Building Of Most Body Parts And Their Action Is Channeled Through A Kaleidoscopic Series Of Environmental Influences: Embryonic And Postnatal, Internal And External. Parts Are Not Translated Genes, And Selection Doesn't Even Work Directly On Parts.

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.

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.)

All Interesting Issues In Natural History Are Questions Of Relative Frequency, Not Single Examples. Everything Happens Once Amidst The Richness Of Nature. But When An Unanticipated Phenomenon Occurs Again And Again—finally Turning Into An Expectation—then Theories Are Overturned.

If We Are Still Here To Witness The Destruction Of Our Planet Some Five Billion Years Or More Hence, Then We Will Have Achieved Something So Unprecedented In The History Of Life That We Should Be Willing To Sing Our Swansong With Joy - Sic Transit Gloria Mundi.

History Of Life

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.

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

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

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.

Is Uniformitarianism Necessary?

Recapitulation Provided A Convenient Focus For The Persuasive Racism Of White Scientists; They Looked To The Activities Of Their Own Children For Comparison With Normal Adult Behavior In Lower Races.

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

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.

Facts Do Not 'speak For Themselves'; They Are Read In The Light Of Theory.

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.

[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.

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

Details Are All That Matters; God Dwells In These And You Never Get To See Him If You Don't Struggle To Get Them Right.

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 Their Recently Aborted Struggle To Inject Genesis Literalism Into Science Classrooms, Fundamentalist Groups Followed Their Usual Opportunistic Strategy Of Arguing Two Contradictory Sides Of A Question When A Supposed Rhetorical Advantage Could Be Extracted From Each.

In Our Struggle To Understand The History Of Life, We Must Learn Where To Place The Boundary Between Contingent And Unpredictable Events That Occur But Once And The More Repeatable, Lawlike Phenomenon That May Pervade Life's History As Generalities.

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.

We Pass Through This World But Once.

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.

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.

The Enemy Of Knowledge And Science Is Irrationalism, Not Religion

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.

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).

Evolution Is A Process Of Constant Branching And Expansion.

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

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

The Contingency Of History (both For Life In General And For The Cultures Of Homo Sapiens ) And Human Free Will (in The Factual Rather Than Theological Sense) Are Conjoined Concepts, And No Better Evidence Can Be Produced Than The "experimental" Production Of Markedly Different Solutions In Identical Environments.

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.

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

Life Is Short, And Potential Studies Infinite. We Have A Much Better Chance Of Accomplishing Something Significant When We Follow Our Passionate Interests And Work In Areas Of Deepest Personal Meaning.

The History Of Life Is More Adequately Represented By A Picture Of 'punctuated Equilibria' Than By The Notion Of Phyletic Gradualism. The History Of Evolution Is Not One Of Stately Unfolding, But A Story Of Homeostatic Equilibria, Disturbed Only 'rarely' (i.e. Rather Often In The Fullness Of Time) By Rapid And Episodic Events Of Speciation.

History Of Life

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.

Few Tragedies Can Be More Extensive Than The Stunting Of Life, Few Injustices Deeper Than The Denial Of An Opportunity To Strive Or Even To Hope, By A Limit Imposed From Without, But Falsely Identified As Lying Within.

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

The Absence Of Fossil Evidence For Intermediary Stages Between Major Transitions In Organic Design, Indeed Our Inability, Even In Our Imagination, To Construct Functional Intermediates In Many Cases, Has Been A Persistent And Nagging Problem For Gradualist Accounts Of Evolution.

Forelimbs Of People, Porpoises, Bats And Horses Provide The Classic Example Of Homology In Most Textbooks. They Look Different, And Do Different Things, But Are Built Of The Same Bones. No Engineer, Starting From Scratch Each Time, Would Have Built Such Disparate Structures From The Same Parts.

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.

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.

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.

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.

So Much Of Science Proceeds By Telling Stories.

Telling Stories

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.

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

The Telephone Is The Greatest Single Enemy Of Scholarship; For What Our Intellectual Forebears Used To Inscribe In Ink Now Goes Once Over A Wire Into Permanent Oblivion.

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

...we Must Be Wary Of Granting Too Much Power To Natural Selection By Viewing All Basic Capacities Of Our Brain As Direct Adaptations.

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

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.

It Is So Hard For An Evolutionary Biologist To Write About Extinction Caused By Human Stupidity. Let Me Then Float An Unconventional Plea, The Inverse Of The Usual Argument. The Extinction Of Partula Is Unfair To Partula. That Is The Conventional Argument, And I Do Not Challenge Its Primacy. But We Need A Humanistic Ecology As Well, Both For The Practical Reason That People Will Always Touch People More Than Snails Do Or Can, And For The Moral Reason That Humans Are Legitimately The Measure Of All Ethical Questions For These Are Our Issues, Not Nature's.

Ethical Questions

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.

... A Local, Indigenous, American Bizarre-ity.

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.

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

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.

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.

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.

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.

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.

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.

Skepticism's Bad Rap Arises From The Impression That, However Necessary The Activity, It Can Only Be Regarded As A Negative Removal Of False Claims. Not So... Proper Debunking Is Done In The Interest Of An Alternate Model Of Explanation, Not As A Nihilistic Exercise. The Alternate Model Is Rationality Itself, Tied To Moral Decency--the Most Powerful Joint Instrument For Good That Our Planet Has Ever Known.

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

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.

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.

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

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.

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.

Very Little Comes Easily To Our Poor, Benighted Species (the First Creature, After All, To Experiment With The Novel Evolutionary Inventions Of Self-conscious Philosophy And Art). Even The Most "obvious," "accurate," And "natural" Style Of Thinking Or Drawing Must Be Regulated By History And Won By Struggle. Solutions Must Therefore Arise Within A Social Context And Record The Complex Interactions Of Mind And Environment That Define The Possibility Of Human Improvement.

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

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.

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.

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

The World, Unfortunately, Rarely Matches Our Hopes And Consistently Refuses To Behave In A Reasonable Manner.

No Rational Order Of Divine Intelligence Unites Species. The Natural Ties Are Genealogical Along Contingent Pathways Of History.

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.

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.

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.

Darwin's Principle Of Natural Selection Leads To The Prediction That The Proper Way To Analyze Any Evolutionary Development Is To See The New Features As Adaptive To Environments. And That's A Perfectly Good Principle. The Problem Is That There Are Many Evolutionary Biologists Who View Everything That Happens In Evolution As Directly Evolved For Adaptive Benefit. And That Just Doesn't Work. Whenever You Build A Structure For Adaptive Reasons, The Structure Is Going To Exhibit Properties That Have Nothing To Do With Adaptation. They're Just Side Consequences.

If New Species Arise Very Rapidly In Small, Peripherally Isolated Local Populations, Then The Great Expectation Of Insensibly Graded Fossil Sequences Is A Chimera. A New Species Does Not Evolve In The Area Of Its Ancestors; It Does Not Arise From The Slow Transformation Of All Its Forbears. Co-author With Niles Eldridge

Why Get Excited Over This Latest Episode In The Long, Sad History Of American Anti-intellectualism? Let Me Suggest That, As Patriotic Americans, We Should Cringe In Embarrassment That, At The Dawn Of A New, Technological Millennium, A Jurisdiction In Our Heartland Has Opted To Suppress One Of The Greatest Triumphs Of Human Discovery.

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

Theory-free Science Makes About As Much Sense As Value-free Politics.

The Causes Of Life's History [cannot] Resolve The Riddle Of Life's Meaning.

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.

Ordinary Speciation Remains Fully Adequate To Explain The Causes And Phenomenology Of Punctuation.

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.

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