... Probably All The Organic Beings Which Have Ever Lived On This Earth Have Descended From Some One Primordial Form, Into Which Life Was First Breathed.

I Look At The Natural Geological Record As A History Of The World Imperfectly Kept And Written In A Changing Dialect; Of This History We Possess The Last Volume Alone, Relating Only To Two Or Three Countries. Of This Volume, Only Here And There A Short Chapter Has Been Preserved; And Of Each Page, Only Here And There A Few Lines.

It Is Scarcely Possible To Doubt That The Love Of Man Has Become Instinctive In The Dog.

I See No Good Reason Why The Views Given This Volume [the Origin Of Species] Should Shock The Religious Feelings Of Any One. It Is Satisfactory, As Showing How Transient Such Impressions Are, To Remember That The Greatest Discovery Ever Made By Man, Namely, The Law Of Attraction Of Gravity, Was Also Attacked By Leibnitz, 'as Subversive Of Natural, And Inferentially Of Revealed, Religion.'

As The Sense Of Smell Is So Intimately Connected With That Of Taste, It Is Not Surprising That An Excessively Bad Odour Should Excite Wretching Or Vomitting In Some Persons.

The Age-old And Noble Thought Of 'i Will Lay Down My Life To Save Another,' Is Nothing More Than Cowardice.

We May Confidently Come To The Conclusion, That The Forces Which Slowly And By Little Starts Uplift Continents, And That Those Which At Successive Periods Pour Forth Volcanic Matter From Open Orifices, Are Identical.

A Grain In The Balance Will Determine Which Individual Shall Live And Which Shall Die - Which Variety Or Species Shall Increase In Number, And Which Shall Decrease, Or Finally Become Extinct.

Our Descent, Then, Is The Origin Of Our Evil Passions!! The Devil Under Form Of Baboon Is Our Grandfather.

The Presence Of A Body Of Well-instructed Men, Who Have Not To Labor For Their Daily Bread, Is Important To A Degree Which Cannot Be Overestimated; As All High Intellectual Work Is Carried On By Them, And On Such Work Material Progress Of All Kinds Mainly Depends, Not To Mention Other And Higher Advantages.

Even The Humblest Mammal's Strong Sexual, Parental, And Social Instincts Give Rise To 'do Unto Others As Yourself' And 'love Thy Neighbor As Thyself'.

[t]he Young And The Old Of Widely Different Races, Both With Man And Animals, Express The Same State Of Mind By The Same Movements.

The Traveler May Feel Assured, He Will Meet With No Difficulties Or Dangers, Excepting In Rare Cases, Nearly So Bad As He Beforehand Anticipates. In A Moral Point Of View, The Effect Ought To Be, To Teach Him Good-humored Patience, Freedom From Selfishness, The Habit Of Acting For Himself, And Of Making The Best Of Every Occurrence.

Besides Love And Sympathy, Animals Exhibit Other Qualities Connected With The Social Instincts Which In Us Would Be Called Moral.

About Weak Points [of The Origin] I Agree. The Eye To This Day Gives Me A Cold Shudder, But When I Think Of The Fine Known Gradations, My Reason Tells Me I Ought To Conquer The Cold Shudder.

On The Ordinary View Of Each Species Having Been Independently Created, We Gain No Scientific Explanation.

I Can Remember The Very Spot In The Road, Whilst In My Carriage, When To My Joy The Solution Occurred To Me.

That There Is Much Suffering In The World No One Disputes. Which Is More Likely, That Pain And Evil Are The Result Of An All-powerful And Good God, Or The Product Of Uncaring Natural Forces? The Presence Of Much Suffering Agrees Well With The View That All Organic Beings Have Been Developed Through Variation And Natural Selection.

So Great Is The Economy Of Nature, That Most Flowers Which Are Fertilised By Crepuscular Or Nocturnal Insects Emit Their Odour Chiefly Or Exclusively In The Evening.

Consequently, If My Theory Be True, It Is Indisputable That Before The Lowest Silurian Stratum Was Deposited, Long Periods Elapsed, As Long As, Or Probably Far Longer Than, The Whole Interval From The Silurian Age To The Present Day; And That During These Vast, Yet Quite Unknown, Periods Of Time, The World Swarmed With Living Creatures. To The Question Why We Do Not Find Records Of These Vast Primordial Periods, I Can Give No Satisfactory Answer.

As Natural Selection Acts By Competition, It Adapts The Inhabitants Of Each Country Only In Relation To The Degree Of Perfection Of Their Associates; So That We Need Feel No Surprise At The Inhabitants Of Any One Country, Although On The Ordinary View Supposed To Have Been Specially Created And Adapted For That Country, Being Beaten And Supplanted By The Naturalised Productions From Another Land.

We Will Now Discuss In A Little More Detail The Struggle For Existence.

The Most Powerful Natural Species Are Those That Adapt To Environmental Change Without Losing Their Fundamental Identity Which Gives Them Their Competitive Advantage.

I Never Gave Up Christianity Until I Was Forty Years Of Age.

A Moral Being Is One Who Is Capable Of Reflecting On His Past Actions And Their Motives - Of Approving Of Some And Disapproving Of Others.

I Would Give Absolutely Nothing For The Theory Of Natural Selection, If It Requires Miraculous Additions At Any One Stage Of Descent.

The Instruction At Edinburgh Was Altogether By Lectures, And These Were Intolerably Dull, With The Exception Of Those On Chemistry.

Ultimately A Highly Complex Sentiment, Having Its First Origin In The Social Instincts, Largely Guided By The Approbation Of Our Fellow-men, Ruled By Reason, Self-interest, And In Later Times By Deep Religious Feelings, Confirmed By Instruction And Habit, All Combined, Constitute Our Moral Sense Or Conscience.

I Have Tried Lately To Read Shakespeare, And Found It So Intolerably Dull That It Nauseated Me.

Man Himself Cannot Express Love And Humility By External Signs, So Plainly As Does A Dog, When With Drooping Ears, Hanging Lips, Flexuous Body, And Wagging Tail, He Meets His Beloved Master.

It Is Often Said That All The Conditions For The First Production Of A Living Organism Are Now Present, Which Could Ever Have Been Present. But If (and Oh! What A Big If!) We Could Conceive In Some Warm Little Pond, With All Sorts Of Ammonia And Phosphoric Salts, Light, Heat, Electricity, &c., Present, That A Proteine Compound Was Chemically Formed Ready To Undergo Stillmore Complex Changes, At The Present Day Such Matter Would Be Instantly Devoured Or Absorbed, Which Would Not Have Been The Case Before Living Creatures Were Formed.

...i Feel Most Deeply That The Whole Subject Is Too Profound For The Human Intellect. A Dog Might As Well Speculate On The Mind Of Newton.— Let Each Man Hope & Believe What He Can.—

How So Many Absurd Rules Of Conduct, As Well As So Many Absurd Religious Beliefs, Have Originated, We Do Not Know; Nor How It Is That They Have Become, In All Quarters Of The World, So Deeply Impressed On The Minds Of Men; But It Is Worthy Of Remark That A Belief Constantly Inculcated During The Early Years Of Life, While The Brain Is Impressionable, Appears To Acquire Almost The Nature Of An Instinct; And The Very Essence Of An Instinct Is That It Is Followed Independently Of Reason.

We Are Optimists, Until We Are Not.

Worms Have Played A More Important Part In The History Of The World Than Humans Would At First Suppose.

There Are Several Other Sources Of Enjoyment In A Long Voyage, Which Are Of A More Reasonable Nature. The Map Of The World Ceases To Be A Blank; It Becomes A Picture Full Of The Most Varied And Animated Figures.

Nothing Exists For Itself Alone, But Only In Relation To Other Forms Of Life

Man In His Arrogance Thinks Himself A Great Work, Worthy The Interposition Of A Great Deity. More Humble And I Believe True To Consider Him Created From Animals.

Man Scans With Scrupulous Care The Character And Pedigree Of His Horses, Cattle, And Dogs Before He Matches Them; But When He Comes To His Own Marriage He Rarely, Or Never, Takes Any Such Care.

We Thus Learn That Man Is Descended From A Hairy Quadruped, Furnished With A Tail And Pointed Ears, Probably Arboreal In Its Habits, And An Inhabitant Of The Old World.

It Is A Truly Wonderful Fact - The Wonder Of Which We Are Apt To Overlook From Familiarity - That All Animals And All Plants Throughout All Time And Space Should Be Related To Each Other In Group Subordinate To Group.

It Has Been A Bitter Mortification For Me To Digest The Conclusion That The "race Is For The Strong" And That I Shall Probably Do Little More But Be Content To Admire The Strides Others Made In Science.

A Scientific Man Ought To Have No Wishes, No Affections, - A Mere Heart Of Stone.

Believing As I Do That Man In The Distant Future Will Be A Far More Perfect Creature Than He Now Is, It Is An Intolerable Thought That He And All Other Sentient Beings Are Doomed To Complete Annihilation After Such Long-continued Slow Progress.

What Wretched Doings Come From The Ardor Of Fame; The Love Of Truth Alone Would Never Make One Man Attack Another Bitterly.

Ignorance More Frequently Begets Confidence Than Does Knowledge: It Is Those Who Know Little, And Not Those Who Know Much, Who So Positively Assert That This Or That Problem Will Never Be Solved By Science.

There Is No Fundamental Difference Between Man And The Higher Mammals In Their Mental Faculties...the Difference In Mind Between Man And The Higher Animals, Great As It Is, Certainly Is One Of Degree And Not Of Kind.

I Am A Firm Believer, That Without Speculation There Is No Good And Original Observation.

May We Not Suspect That The Vague But Very Real Fears Of Children, Which Are Quite Independent Of Experience, Are The Inherited Effects Of Real Dangers And Abject Superstitions During Ancient Savage Times?

Who When Examining In The Cabinet Of The Entomologist The Gay And Exotic Butterflies, And Singular Cicadas, Will Associate With These Lifeless Objects, The Ceaseless Harsh Music Of The Latter, And The Lazy Flight Of The Former - The Sure Accompaniments Of The Still, Glowing Noonday Of The Tropics.

I Think It Inevitably Follows, That As New Species In The Course Of Time Are Formed Through Natural Selection, Others Will Become Rarer And Rarer, And Finally Extinct. The Forms Which Stand In Closest Competition With Those Undergoing Modification And Improvement Will Naturally Suffer Most.

It May Be Doubted That There Are Many Other Animals Which Have Played So Important A Part In The History Of The World As Have These Lowly Organized Creatures.

I Find In The Domestic Duck That The Bones Of The Wing Weigh Less And The Bones Of The Leg More, In Proportion To The Whole Skeleton, Than Do The Same Bones In The Wild Duck; And This Change May Be Safely Attributed To The Domestic Duck Flying Much Less, And Walking More, Than Its Wild Parents.

When The Views Entertained In This Volume On The Origin Of Species, Or When Analogous Views Are Generally Admitted, We Can Dimly Forsee That There Will Be A Considerable Revolution In Natural History.

I Had Gradually Come, By This Time [1839-01], To See That The Old Testament From Its Manifestly False History Of The World, With The Tower Of Babel, The Rainbow As A Sign, Etc., Etc. And From Its Attributing To God The Feelings Of A Revengeful Tyrant, Was No More To Be Trusted Than The Sacred Books Of The Hindoos, Or The Beliefs Of Any Barbarian.

I Liked The Thought Of Being A Country Clergyman. Accordingly I Read With Care Pearson On The Creed And A Few Other Books On Divinity; And As I Did Not Then In The Least Doubt The Strict And Literal Truth Of Every Word In The Bible, I Soon Persuaded Myself That Our Creed Must Be Fully Accepted.

The World Will Not Be Inherited By The Strongest, It Will Be Inherited By Those Most Able To Change.

False Facts Are Highly Injurious To The Progress Of Science, For They Often Endure Long; But False Views, If Supported By Some Evidence, Do Little Harm, For Every One Takes A Salutary Pleasure In Proving Their Falseness.

I Have Been Speculating Last Night What Makes A Man A Discoverer Of Undiscovered Things; And A Most Perplexing Problem It Is. Many Men Who Are Very Clever - Much Cleverer Than The Discoverers - Never Originate Anything.

If The Misery Of The Poor Be Caused Not By The Laws Of Nature, But By Our Institutions, Great Is Our Sin.

It At Once Struck Me That Under These Circumstances Favourable Variations Would Tend To Be Preserved, And Unfavourable Ones To Be Destroyed.

Man Is Developed From An Ovule, About 125th Of An Inch In Diameter, Which Differs In No Respect From The Ovules Of Other Animals.

I Can Indeed Hardly See How Anyone Ought To Wish Christianity To Be True For If So The Plain Language Of The Text Seems To Show That The Men Who Do Not Believe, And This Would Include My Father, Brother And Almost All Of My Friends, Will Be Everlastingly Punished. And This Is A Damnable Doctrine.

In Regard To The Amount Of Difference Between The Races, We Must Make Some Allowance For Our Nice Powers Of Discrimination Gained By A Long Habit Of Observing Ourselves.

The Western Nations Of Europe, Who Now So Immeasurably Surpass Their Former Savage Progenitors, And Stand At The Summit Of Civilization, Owe Little Or None Of Their Superiority To Direct Inheritance From The Old Greeks, Though They Owe Much To The Written Works Of That Wonderful People.

Man Selects Only For His Own Good: Nature Only For That Of The Being Which She Tends.

Origin Of Species

I Have Watched How Steadily The General Feeling, As Shown At Elections, Has Been Rising Against Slavery. What A Proud Thing For England If She Is The First European Nation Which Utterly Abolishes It! I Was Told Before Leaving England That After Living In Slave Countries All My Opinions Would Be Altered; The Only Alteration I Am Aware Of Is Forming A Much Higher Estimate Of The Negro Character.

For My Own Part I Would As Soon Be Descended From That Heroic Little Monkey, Who Braved His Dreaded Enemy In Order To Save The Life Of His Keeper; Or From That Old Baboon, Who, Descending From The Mountains, Carried Away In Triumph His Young Comrade From A Crowd Of Astonished Dogs-as From A Savage Who Delights To Torture His Enemies, Offers Up Bloody Sacrifices, Practices Infanticide Without Remorse, Treats His Wives Like Slaves, Knows No Decency, And Is Haunted By The Grossest Superstitions.

Why Does Man Regret, Even Though He May Endeavour To Banish Any Such Regret, That He Has Followed The One Natural Impulse, Rather Than The Other; And Why Does He Further Feel That He Ought To Regret His Conduct? Man In This Respect Differs Profoundly From The Lower Animals.

I Am Almost Convinced (quite Contrary To Opinion I Started With) That Species Are Not (it Is Like Confessing A Murder) Immutable.

Seeing This Gradation And Diversity Of Structure In One Small, Intimately Related Group Of Birds, One Might Really Fancy That From An Original Paucity Of Birds In This Archipelago, One Species Had Been Taken And Modified For Different Ends.

Even People Who Aren’t Geniuses Can Outthink The Rest Of Mankind If They Develop Certain Thinking Habits.

But Then With Me The Horrid Doubt Always Arises Whether The Convictions Of Man's Mind, Which Has Been Developed From The Mind Of The Lower Animals, Are Of Any Value Or At All Trustworthy. Would Any One Trust In The Convictions Of A Monkey's Mind, If There Are Any Convictions In Such A Mind?

An American Monkey, After Getting Drunk On Brandy, Would Never Touch It Again, And Thus Is Much Wiser Than Most Men.

Each Organic Being Is Striving To Increase In A Geometrical Ratio . . .

I Cannot Persuade Myself That A Beneficient And Omnipotent God Would Have Designedly Created...that A Cat Should Play With Mice.

Man Is More Courageous, Pugnacious, And Energetic Than Woman, And Has A More Inventive Genius. His Brain Is Absolutely Larger, But Whether Relatively To The Larger Size Of His Body, In Comparison With That Of Woman, Has Not, I Believe Been Fully Ascertained. In Woman The Face Is Rounder; The Jaws And The Base Of The Skull Smaller; The Outlines Of Her Body Rounder, In Parts More Prominent; And Her Pelvis Is Broader Than In Man; But This Latter Character May Perhaps Be Considered Rather As A Primary Than A Secondary Sexual Character. She Comes To Maturity At An Earlier Age Than Man.

Linnaeus And Cuvier Have Been My Two Gods, Though In Very Different Ways, But They Were Mere Schoolboys To Old Aristotle.

I Have Just Finished My Sketch Of My Species Theory. If As I Believe That My Theory Is True & If It Be Accepted Even By One Competent Judge, It Will Be A Considerable Step In Science. I Therefore Write This, In Case Of My Sudden Death, As My Most Solemn & Last Request, Which I Am Sure You Will Consider The Same As If Legally Entered In My Will, That You Will Devote 400£ To Its Publication & Further Will Yourself, Or Through Hensleigh [wedgwood], Take Trouble In Promoting It.

The Question Of Whether There Exists A Creator And Ruler Of The Universe Has Been Answered In The Affirmative By Some Of The Highest Intellects That Have Ever Existed.

Thus Disbelief Crept Over Me At A Very Slow Rate, But At Last Was Complete. The Rate Was So Slow That I Felt No Distress, And Have Never Since Doubted Even For A Single Second That My Conclusion Was Correct.

For I Am Well Aware That Scarcely A Single Point Is Discussed In This Volume On Which Facts Cannot Be Adduced, Often Apparently Leading To Conclusions Directly Opposite To Those At Which I Have Arrived. A Fair Result Can Be Obtained Only By Fully Stating And Balancing The Facts And Arguments On Both Sides Of Each Question.

A Mathematician Is A Blind Man In A Dark Room Looking For A Black Cat Which Isn't There.

You Will Be Astonished To Find How The Whole Mental Disposition Of Your Children Changes With Advancing Years. A Young Child And The Same When Nearly Grown, Sometimes Differ Almost As Much As Do A Caterpillar And Butterfly.

Nothing Is Easier Than To Admit In Words The Truth Of The Universal Struggle For Life, Or More Difficult--at Least I Have Found It So--than Constantly To Bear This Conclusion In Mind.

If A Person Asked My Advice, Before Undertaking A Long Voyage, My Answer Would Depend Upon His Possessing A Decided Taste For Some Branch Of Knowledge, Which Could By This Means Be Advanced. No Doubt It Is A High Satisfaction To Behold Various Countries And The Many Races Of Mankind, But The Pleasures Gained At The Time Do Not Counterbalance The Evils.

Sympathy For The Lowest Animals Is One Of The Noblest Virtues With Which Man Is Endowed.

The Chief Distinction In The Intellectual Powers Of The Two Sexes Is Shown By Mans Attaining To A Higher Eminence, In Whatever He Takes Up, Than The Woman. Whether Deep Thought, Reason, Or Imagination Or Merely The Use Of The Senses And Hands.....we May Also Infer.....the Average Mental Power In Man Must Be Above That Of Woman.

Even When We Are Quite Alone, How Often Do We Think With Pleasure Or Pain Of What Others Think Of Us - Of Their Imagined Approbation Or Disapprobation.

Sympathy Beyond The Confines Of Man, That Is, Humanity To The Lower Animals, Seems To Be One Of The Latest Moral Acquisitions.

I Fully Subscribe To The Judgement Of Those Writers Who Maintain That Of All The Differences Between Man And The Lower Animal, The Moral Sense Of Conscience Is By Far The Most Important....it Is The Most Noble Of All The Attributes Of Man.

I Was A Young Man With Uninformed Ideas. I Threw Out Queries, Suggestions, Wondering All The Time Over Everything; And To My Astonishment The Ideas Took Like Wildfire. People Made A Religion Of Them.

Nothing Can Be More Hopeless Than To Attempt To Explain This Similarity Of Pattern In Members Of The Same Class, By Utility Or By The Doctrine Of Final Causes.

I Feel Like An Old Warhorse At The Sound Of A Trumpet When I Read About The Capturing Of Rare Beetles.

As Man Advances In Civilization, And Small Tribes Are United Into Larger Communities, The Simplest Reason Would Tell Each Individual That He Ought To Extend His Social Instincts And Sympathies To All Members Of The Same Nation, Though Personally Unknown To Him. This Point Being Once Reached, There Is Only An Artificial Barrier To Prevent His Sympathies Extending To The Men Of All Nations And Races.

I Have Called This Principle, By Which Each Slight Variation, If Useful, Is Preserved, By The Term Natural Selection, In Order To Mark Its Relation To Man's Power Of Selection. But The Expression Often Used By Mr. Herbert Spencer Of The Survival Of The Fittest Is More Accurate, And Is Sometimes Equally Convenient.

I Am Dying By Inches, From Not Having Any Body To Talk To About Insects.

Everything In Nature Is The Result Of Fixed Laws.

Mr. J.s. Mill Speaks, In His Celebrated Work, "utilitarianism," Of The Social Feelings As A "powerful Natural Sentiment," And As "the Natural Basis Of Sentiment For Utilitarian Morality," But On The Previous Page He Says, "if, As Is My Own Belief, The Moral Feelings Are Not Innate, But Acquired, They Are Not For That Reason Less Natural." It Is With Hesitation That I Venture To Differ From So Profound A Thinker, But It Can Hardly Be Disputed That The Social Feelings Are Instinctive Or Innate In The Lower Animals; And Why Should They Not Be So In Man?

To Suppose That The Eye, With All Its Inimitable Contrivances For Adjusting The Focus To Different Distances, For Admitting Different Amounts Of Light, And For The Correction Of Spherical And Chromatic Aberration, Could Have Been Formed By Natural Selection, Seems, I Freely Confess, Absurd In The Highest Possible Degree.

He Who Is Not Content To Look, Like A Savage, At The Phenomena Of Nature As Disconnected, Cannot Any Longer Believe That Man Is The Work Of A Separate Act Of Creation ... Man Is The Co-descendant With Other Mammals Of A Common Progenitor.

A Language, Like A Species, When Extinct, Never... Reappears.

... If Variations Useful To Any Organic Being Do Occur, Assuredly Individuals Thus Characterized Will Have The Best Chance Of Being Perserved In The Struggle For Life; And From The Strong Principle Of Inheritance They Will Tend To Produce Offsping Similarly Characterized.

To Conclude, Therefore, Let No Man Out Of A Weak Conceit Of Sobriety, Or An Ill-applied Moderation, Think Or Maintain, That A Man Can Search Too Far Or Be Too Well Studied In The Book Of God's Word, Or In The Book Of God's Works; Divinity Or Philosophy; But Rather Let Men Endeavour An Endless Progress Or Proficience In Both."—bacon: "advancement Of Learning".

Some Few, And I Am One Of Them, Even Wish To God, Though At The Loss Of Millions Of Lives, That The North Would Proclaim A Crusade Against Slavery. In The Long-run, A Million Horrid Deaths Would Be Amply Repaid In The Cause Of Humanity. Great God! How I Should Like To See The Greatest Curse On Earth - Slavery - Abolished!

It Is Really Laughable To See What Different Ideas Are Prominent In Various Naturalists' Minds, When They Speak Of 'species'; In Some, Resemblance Is Everything And Descent Of Little Weight-in Some, Resemblance Seems To Go For Nothing, And Creation The Reigning Idea-in Some, Descent Is The Key,-in Some, Sterility An Unfailing Test, With Others It Is Not Worth A Farthing. It All Comes, I Believe, From Trying To Define The Undefinable.

But Just In Proportion As This Process Of Extermination Has Acted On An Enormous Scale, So Must The Number Of Intermediate Varieties, Which Have Formerly Existed, Be Truly Enormous. Why Then Is Not Every Geological Formation And Every Stratum Full Of Such Intermediate Links? Geology Assuredly Does Not Reveal Any Such Finely Graduated Organic Chain; And This, Perhaps, Is The Most Obvious And Serious Objection Which Can Be Urged Against The Theory. The Explanation Lies, As I Believe, In The Extreme Imperfection Of The Geological Record.

It Is Well-known That Those Who Have Charge Of Young Infants, That It Is Difficult To Feel Sure When Certain Movements About Their Mouths Are Really Expressive; That Is When They Really Smile. Hence I Carefully Watched My Own Infants. One Of Them At The Age Of Forty-five Days, And Being In A Happy Frame Of Mind, Smiled... I Observed The Same Thing On The Following Day: But On The Third Day The Child Was Not Quite Well And There Was No Trace Of A Smile, And This Renders It Probable That The Previous Smiles Were Real.

It Is Not The Most Intellectual Of The Species That Survives; It Is Not The Strongest That Survives; But The Species That Survives Is The One That Is Able Best To Adapt And Adjust To The Changing Environment In Which It Finds Itself.

Changing Environment

How Fleeting Are The Wishes And Efforts Of Man! How Short His Time! And Consequently How Poor Will His Products Be, Compared With Those Accumulated By Nature During Whole Geological Periods. Can We Wonder, Then, That Nature's Productions Should Be Far 'truer' In Character Than Man's Productions; That They Should Be Infinitely Better Adapted To The Most Complex Conditions Of Life, And Should Plainly Bear The Stamp Of Far Higher Workmanship?

During My Second Year At Edinburgh [1826-27] I Attended Jameson's Lectures On Geology And Zoology, But They Were Incredible Dull. The Sole Effect They Produced On Me Was The Determination Never As Long As I Lived To Read A Book On Geology.

I Have Rarely Read Anything Which Has Interested Me More, Though I Have Not Read As Yet More Than A Quarter Of The Book Proper. From Quotations Which I Had Seen, I Had A High Notion Of Aristotle's Merits, But I Had Not The Most Remote Notion What A Wonderful Man He Was. Linnaeus And Cuvier Have Been My Two Gods, Though In Very Different Ways, But They Were Mere Schoolboys To Old Aristotle.

Of All The Differences Between Man And The Lower Animals, The Moral Sense Or Conscience Is By Far The Most Important. This Sense, As Mackintosh Remarks, "has A Rightful Supremacy Over Every Other Principle Of Human Action"; It Is Summed Up In That Short But Imperious Word "ought," So Full Of High Significance. It Is The Most Noble Of All The Attributes Of Man, Leading Him Without A Moment's Hesitation To Risk His Life For That Of A Fellow-creature; Or After Due Deliberation, Impelled Simply By The Deep Feeling Of Right Or Duty, To Sacrifice It In Some Great Cause.

Now When Naturalists Observe A Close Agreement In Numerous Small Details Of Habits, Tastes And Dispositions Between Two Or More Domestic Races, Or Between Nearly-allied Natural Forms, They Use This Fact As An Argument That All Are Descended From A Common Progenitor Who Was Thus Endowed; And Consequently That All Should Be Classed Under The Same Species. The Same Argument May Be Applied With Much Force To The Races Of Man.

This Fundamental Subject Of Natural Selection Will Be Treated At Some Length In The Fourth Chapter; And We Shall Then See How Natural Selection Almost Inevitably Causes Much Extinction Of The Less Improved Forms Of Life And Induces What I Have Called Divergence Of Character.

The More Efficient Causes Of Progress Seem To Consist Of A Good Education During Youth Whilst The Brain Is Impressible, And Of A High Standard Of Excellence, Inculcated By The Ablest And Best Men, Embodied In The Laws, Customs And Traditions Of The Nation, And Enforced By Public Opinion.

If It Could Be Demonstrated That Any Complex Organ Existed, Which Could Not Possibly Have Been Formed By Numerous, Successive, Slight Modifications, My Theory Would Absolutely Break Down. But I Can Find No Such Case.

Evolution Of Man

Extinction Has Only Separated Groups: It Has By No Means Made Them; For If Every Form Which Has Ever Lived On This Earth Were Suddenly To Reappear, Though It Would Be Quite Impossible To Give Definitions By Which Each Group Could Be Distinguished From Other Groups, As All Would Blend Together By Steps As Fine As Those Between The Finest Existing Varieties, Nevertheless A Natural Classification, Or At Least A Natural Arrangement, Would Be Possible.

You Ask About My Opinion On Vivisection. I Quite Agree That It Is Justifiable For Real Investigations On Physiology; But Not For Mere Damnable And Detestable Curiosity.

Describing Laughter: The Sound Is Produced By A Deep Inspiration Followed By Short, Interrupted, Spasmodic Contractions Of The Chest, And Especially The Diaphragm... The Mouth Is Open More Or Less Widely, With The Corners Drawn Much Backwards, As Well As A Little Upwards; And The Upper Lip Is Somewhat Raised.

Progress Has Been Much More General Than Retrogression

The More I Study Nature, The More I Become Impressed With Ever-increasing Force With The Conclusion, That The Contrivances And Beautiful Adaptations Slowly Acquired Through Each Part Occasionally Varying In A Slight Degree But In Many Ways, With The Preservation Or Natural Selection Of Those Variations Which Are Beneficial To The Organism Under The Complex And Ever-varying Conditions Of Life, Transcend In An Incomparable Degree The Contrivances And Adaptations Which The Most Fertile Imagination Of Man Could Suggest With Unlimited Time At His Disposal.

The Willing Horse Is Always Overworked.

If Mozart, Instead Of Playing The Pianoforte At Three Years Old With Wonderfully Little Practice, Had Played A Tune With No Practice At All, He Might Truly Have Been Said To Have Done So Instinctively.

The Main Conclusion Arrived At In This Work, Namely That Man Is Descended From Some Lowly-organised Form, Will, I Regret To Think, Be Highly Distasteful To Many Persons. But There Can Hardly Be A Doubt That We Are Descended From Barbarians.

I Agree With Agassiz That Dogs Possess Something Very Like Conscience.

About Thirty Years Ago There Was Much Talk That Geologists Ought Only To Observe And Not Theorise; And I Well Remember Some One Saying That At This Rate A Man Might As Well Go Into A Gravel-pit And Count The Pebbles And Describe The Colours. How Odd It Is That Anyone Should Not See That All Observation Must Be For Or Against Some View If It Is To Be Of Any Service!

There Is Grandeur In This View Of Life, With Its Several Powers, Having Been Originally Breathed Into A Few Forms Or Into One; And That, Whilst This Planet Has Gone Cycling On According To The Fixed Law Of Gravity, From So Simple A Beginning Endless Forms Most Beautiful And Most Wonderful Have Been, And Are Being, Evolved.

The Theory Which I Would Offer, Is Simply, That As The Land With The Attached Reefs Subsides Very Gradually From The Action Of Subterranean Causes, The Coral-building Polypi Soon Raise Again Their Solid Masses To The Level Of The Water: But Not So With The Land; Each Inch Lost Is Irreclaimably Gone; As The Whole Gradually Sinks, The Water Gains Foot By Foot On The Shore, Till The Last And Highest Peak Is Finally Submerged.

It Is A Fatal Fault To Reason Whilst Observing, Though So Necessary Beforehand And So Useful Afterwards.

I Have At Least, As I Hope, Done Good Service In Aiding To Overthrow The Dogma Of Separate Creations.

This Preservation Of Favourable Variations And The Destruction Of Injurious Variations, I Call Natural Selection, Or The Survival Of The Fittest. Variations Neither Useful Nor Injurious Would Not Be Affected By Natural Selection And Would Be Left A Fluctuating Element.

A Man Who Dares To Waste One Hour Of Time Has Not Discovered The Value Of Life.

Another Source Of Conviction In The Existence Of God, Connected With The Reason And Not With The Feelings, Impresses Me As Having Much More Weight. This Follows From The Extreme Difficulty Or Rather Impossibility Of Conceiving This Immense And Wonderful Universe, Including Man With His Capacity Of Looking Far Backwards And Far Into Futurity, As The Result Of Blind Chance Or Necessity. When Thus Reflecting I Feel Compelled To Look To A First Cause Having An Intelligent Mind In Some Degree Analogous To That Of Man; And I Deserve To Be Called A Theist.

The Several Difficulties Here Discussed, Namely Our Not Finding In The Successive Formations Infinitely Numerous Transitional Links Between The Many Species Which Now Exist Or Have Existed; The Sudden Manner In Which Whole Groups Of Species Appear In Our European Formations; The Almost Entire Absence, As At Present Known, Of Fossiliferous Formations Beneath The Silurian Strata, Are All Undoubtedly Of The Gravest Nature.

As Natural Selection Works Solely By And For The Good Of Each Being, All Corporeal And Mental Endowments Will Tend To Progress Toward Perfection.

If I Had Not Been So Great An Invalid, I Should Not Have Done So Much As I Have Accomplished.

The Earthquake, However, Must Be To Every One A Most Impressive Event: The Earth, Considered From Our Earliest Childhood As The Type Of Solidity, Has Oscillated Like A Thin Crust Beneath Our Feet; And In Seeing The Laboured Works Of Man In A Moment Overthrown, We Feel The Insignificance Of His Boasted Power.

...i Believe There Exists, & I Feel Within Me, An Instinct For The Truth, Or Knowledge Or Discovery, Of Something Of The Same Nature As The Instinct Of Virtue, & That Our Having Such An Instinct Is Reason Enough For Scientific Researches Without Any Practical Results Ever Ensuing From Them.
