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.

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.

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.

The Median Isn't The Message.

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).

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.

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.

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.

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.

Most Books, After All, Are Ephemeral; Their Specifics, Several Years Later, Inspire About As Much Interest As Daily Battle Reports From The Hundred Years' War.

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

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

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.

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.

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

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.

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.

As In 1925, Creationists Are Not Battling For Religion. They Have Been Disowned By Leading Church Men Of All Persuasions, For They Debase Religion Even More Than They Misconstrue Science. They Are A Motley Collection To Be Sure, But Their Core Of Practical Support Lies With The Evangelical Right, And Creationism Is A Mere Stalking Horse Or Subsidiary Issue In A Political Program...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'.

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.

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

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.

Current Utility And Historical Origin Are Different Subjects.

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

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

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

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.

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.

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.

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

We Who Revel In Nature's Diversity And Feel Instructed By Every Animal Tend To Brand Homo Sapiens As The Greatest Catastrophe Since The Cretaceous Extinction.

Honorable Errors Do Not Count As Failures In Science, But As Seeds For Progress In The Quintessential Activity Of Correction.

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

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

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.

The Dogmatist Within Is Always Worse Than The Enemy Without.

Evolution Is A Process Of Constant Branching And Expansion.

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?

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

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.

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

[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.

Among People I Have Met, The Few Whom I Would Term “great” All Share A Kind Of Unquestioned, Fierce Dedication; An Utter Lack Of Doubt About The Value Of Their Activities (or At Least An Internal Impulse That Drives Through Any Such Angst); And Above All, A Capacity To Work (or At Least To Be Mentally Alert For Unexpected Insights) At Every Available Moment Of Every Day Of Their Lives.

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

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

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.

We Pass Through This World But Once.

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.

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

In What I Like To Call The Great Asymmetry, Every Spectacular Incident Of Evil Will Be Balanced By 10,000 Acts Of Kindness, Too Often Unnoted And Invisible.

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

I Contend That The Continued Racial Classification Of Homo Sapiens Represents An Outmoded Approach To The General Problem Of Differentiation Within A Species. In Other Words, I Reject A Racial Classification Of Humans For The Same Reasons That I Prefer Not To Divide Into Subspecies The Prodigiously Variable West Indian Land Snails That Form The Subject Of My Own Research.

Differentiation

Science Is Not A Heartless Pursuit Of Objective Information; It Is A Creative Human Activity.

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.

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

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.

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.

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]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.

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

I View The Major Features Of My Own Odyssey As A Set Of Mostly Fortunate Contingencies. I Was Not Destined By Inherited Mentality Or Family Tradition To Become A Paleontologist. I Can Locate No Tradition For Scientific Or Intellectual Careers Anywhere On Either Side Of My Eastern European Jewish Background. I View My Serious And Lifelong Commitment To Baseball In Entirely The Same Manner: Purely As A Contingent Circumstance Of Numerous, Albeit Not Entirely Capricious, Accidents.

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.

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.

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.

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

Einstein's Theory Of Gravitation Replaced Newton's, But Apples Did Not Suspend Themselves In Mid-air, Pending The Outcome. And Humans Evolved From Apelike Ancestors Whether They Did So By Darwin's Proposed Mechanism Or By Some Other Yet To Be Discovered.

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

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

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

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.

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?

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.

The Classical Argument For Why A Supposedly Decent And Moral Creature Like Homo Sapiens Can Mistreat And Even Extirpate Other Species Rests Upon An Extreme Position In A Continuum. The Cartesian Tradition, Formulated Explicitly In The Seventeenth Century, But Developed In "folk" And Other Versions Throughout Human History No Doubt, Holds That Other Animals Are Little More Than Unfeeling Machines, With Only Humans Enjoying "consciousness," However Defined.

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.

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.

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.

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.

Antiessentialist Thinking Forces Us To View The World Differently. We Must Accept Shadings And Continua As Fundamental. We Lose Criteria For Judgment By Comparison To Some Ideal: Short People, Retarded People, People Of Other Beliefs, Colors, And Religions Are People Of Full Status.

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

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

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.

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.

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.

Speciation Does Not Necessarily Promote Evolutionary Change; Rather, Speciation 'gathers In' And Guards Evolutionary Change By Locking And Stabilization For Sufficient Geological Time Within A Darwinian Individual Of The Appropriate Scale. If A Change In A Local Population Does Not Gain Such Protection, It Becomes-to Borrow Dawkins's Metaphor At A Macroevolutionary Scale-a Transient Duststorm In The Desert Of Time, A Passing Cloud Without Borders, Integrity, Or Even The Capacity To Act As A Unit Of Selection, In The Panorama Of Life's Phylogeny.

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

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.

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.

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.

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

The Spandrels Of San Marco And The Panglossian Paradigm.

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.

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).

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

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

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.

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

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

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.

[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.

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.

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

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.

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

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.

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.

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.

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.

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.

Nature Is What She Is - Amoral And Persistent.

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.

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.

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.

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

Phony Psychics Like Uri Geller Have Had Particular Success In Bamboozling Scientists With Ordinary Stage Magic, Because Only Scientists Are Arrogant Enough To Think That They Always Observe With Rigorous And Objective Scrutiny, And Therefore Could Never Be So Fooled While Ordinary Mortals Know Perfectly Well That Good Performers Can Always Find A Way To Trick People.

Life Began Three And A Half Billion Years Ago, Necessarily About As Simple As It Could Be, Because Life Arose Spontaneously From The Organic Compounds In The Primeval Oceans.

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

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).

Surely The Mitochondrion That First Entered Another Cell Was Not Thinking About The Future Benefits Of Cooperation And Integration; It Was Merely Trying To Make Its Own Living In A Tough Darwinian World

Perhaps I Am Just A Hopeless Rationalist, But Isn't Fascination As Comforting As Solace? Isn't Nature Immeasurably More Interesting For Its Complexities And Its Lack Of Conformity To Our Hopes? Isn't Curiosity As Wondrously And Fundamentally Human As Compassion?

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.

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.

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.

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.

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.

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

The Enemy Of Knowledge And Science Is Irrationalism, Not Religion

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).

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

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.

Since The Universe Must Contain Millions Of Appropriate Planets, Consciousness In Some Form - But Not With The Paired Eyes And Limbs, And The Brain Built Of Neurons In The Only Example We Know - May Evolve Frequently. But If Only One Origin Of Life In A Million Ever Leads To Consciousness, Then Martian Bacteria Most Emphatically Do Not Imply Little Green Men.

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.

[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.

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

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.

Nothing Is More Dangerous Than A Dogmatic Worldview.

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

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.

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.

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.

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

In His Anti-darwinian Book... (and Eponymously Named The Neck Of The Giraffe ), Francis Hitching Tells The Story... "the Need To Survive By Reaching Ever Higher For Food Is, Like So Many Darwinian Explanations Of Its Kind, Little More Than A Post Hoc Speculation." Hitching Is Quite Correct, But He Rebuts A Fairy Story That Darwin Was Far Too Smart To Tell - Even Though The Tale Later Entered Our High School Texts As A "classic Case" Nonetheless.

The Board Transported Its Jurisdiction To A Never-never Land Where A Dorothy Of The New Millennium Might Exclaim: "they Still Call It Kansas, But I Don't Think We're In The Real World Anymore."

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.

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.

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.

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'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.

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

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.

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.

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

The Fundamentalists, By 'knowing' The Answers Before They Start, And Then Forcing Nature Into The Straitjacket Of Their Discredited Preconceptions, Lie Outside The Domain Of Science - Or Any Honest Intellectual Inquiry.

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.

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

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.

Is Uniformitarianism Necessary?

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.

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

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.

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.

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.

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

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.

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

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.

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

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

Changing Environment

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.

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.

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

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.

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).

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

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.

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.

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.

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.

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.

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.

Darwinian Evolution May Be The Most Truthful And Powerful Idea Ever Generated By Western Science, But If We Continue To Illustrate Our Conviction With An Indefensible, Unsupported, Entirely Speculative, And Basically Rather Silly Story, Then We Are Clothing A Thing Of Beauty In Rags - And We Should Be Ashamed, "for The Apparel Oft Proclaims The Man.

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

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.

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

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 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.

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 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 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.

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 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.

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.

The Only Universal Attribute Of Scientific Statements Resides In Their Potential Fallibility. If A Claim Cannot Be Disproven, It Does Not Belong To The Enterprise Of Science.

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.

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.

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.

Guessing Right For The Wrong Reason Does Not Merit Scientific Immortality.

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.

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.

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?.
