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 Conscience Which Raises A Blush, For A Man May Sincerely Regret Some Slight Fault Committed In Solitude, Or He May Suffer The Deepest Remorse For An Undetected Crime, But He Will Not Blush... It Is Not The Sense Of Guilt, But The Thought That Others Think Or Know Us To Be Guilty Which Crimsons The Face.

It Strikes Me That All Our Knowledge About The Structure Of Our Earth Is Very Much Like What An Old Hen Would Know Of The Hundred-acre Field In A Corner Of Which She Is Scratching.

Our Ancestor Was An Animal Which Breathed Water, Had A Swim-bladder, A Great Swimming Tail, An Imperfect Skull & Undoubtedly Was An Hermaphrodite! Here Is A Pleasant Genealogy For Mankind.

A Grand And Almost Untrodden Field Of Inquiry Will Be Opened, On The Causes And Laws Of Variation, On Correlation Of Growth, On The Effects Of Use And Disuse, On The Direct Actions Of External Conditions, And So Forth.

In However Complex A Manner This Feeling May Have Originated, As It Is One Of High Importance To All Those Animals Which Aid And Defend One Another, It Will Have Been Increased Through Natural Selection; For Those Communities, Which Included The Greatest Number Of The Most Sympathetic Members, Would Flourish Best, And Rear The Greatest Number Of Offspring.

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.

Freedom Of Thought Is Best Promoted By The Gradual Illumination Of Men’s Minds Which Follows From The Advance Of Science.

It Has Sometimes Been Said That The Success Of The Origin Proved "that The Subject Was In The Air," Or "that Men's Minds Were Prepared For It." I Do Not Think That This Is Strictly True, For I Occasionally Sounded Not A Few Naturalists, And Never Happened To Come Across A Single One Who Seemed To Doubt About The Permanence Of Species.

It Is Mere Rubbish Thinking, At Present, Of Origin Of Life; One Might As Well Think Of Origin Of Matter.

The Man That Created The Theory Of Evolution By Natural Selection Was Thrown Out By His Dad Because He Wanted Him To Be A Doctor. Gawd, Parents Haven't Changed Much.

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.

We Are Optimists, Until We Are Not.

The Explanation Of Types Of Structure In Classes - As Resulting From The Will Of The Deity, To Create Animals On Certain Plans - Is No Explanation. It Has Not The Character Of A Physical Law And Is Therefore Utterly Useless. It Foretells Nothing Because We Know Nothing Of The Will Of The Deity, How It Acts And Whether Constant Or Inconstant Like That Of Man.

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.

The Most Energetic Workers I Have Encountered In My World Travels Are The Vegetarian Miners Of Chile.

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.

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.

Jealousy Was Plainly Exhibited When I Fondled A Large Doll, And When I Weighed His Infant Sister, He Being Then 15? Months Old.

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 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.

The Love Of A Dog For His Master Is Notorious; In The Agony Of Death He Has Been Known To Caress His Master, And Everyone Has Heard Of The Dog Suffering Under Vivisection, Who Licked The Hand Of The Operator; This Man, Unless He Had A Heart Of Stone, Must Have Felt Remorse To The Last Hour Of His Life.

It May Be Conceit, But I Believe The Subject Will Interest The Public, And I Am Sure That The Views Are Original.

Disbelief Crept Over Me At A Very Slow Rate, But At Last It Was Complete.

After My Return To England It Appeared To Me That By Following The Example Of Lyell In Geology, And By Collecting All Facts Which Bore In Any Way On The Variation Of Animals And Plants Under Domestication And Nature, Some Light Might Perhaps Be Thrown On The Whole Subject.

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!

Wherever The European Has Trod, Death Seems To Pursue The Aboriginal.

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.

But Geology Carries The Day: It Is Like The Pleasure Of Gambling, Speculating, On First Arriving, What The Rocks May Be; I Often Mentally Cry Out 3 To 1 Tertiary Against Primitive; But The Latter Have Hitherto Won All The Bets.

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 Believe We Were All Glad To Leave New Zealand. It Is Not A Pleasant Place. Amongst The Natives There Is Absent That Charming Simplicity .... And The Greater Part Of The English Are The Very Refuse Of Society.

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.

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

Nevertheless So Profound Is Our Ignorance, And So High Our Presumption, That We Marvel When We Hear Of The Extinction Of An Organic Being; And As We Do Not See The Cause, We Invoke Cataclysms To Desolate The World, Or Invent Laws On The Duration Of The Forms Of Life!

My Books Have Sold Largely In England, Have Been Translated Into Many Languages, And Passed Through Several Editions In Foreign Countries. I Have Heard It Said That The Success Of A Work Abroad Is The Best Test Of Its Enduring Value. I Doubt Whether This Is At All Trustworthy; But Judged By This Standard My Name Ought To Last For A Few Years.

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.

As For A Future Life, Every Man Must Judge For Himself Between Conflicting Vague Probabilities.

I Am Aware That The Conclusions Arrived At In This Work Will Be Denounced By Some As Highly Irreligious; But He Who Denounces Them Is Bound To Show Why It Is More Irreligious To Explain The Origin Of Man As A Distinct Species By Descent From Some Lower From, Through The Laws Of Variation And Natural Selection, Than To Explain The Birth Of The Individual Through The Laws Of Ordinary Reproduction. The Birth Both Of The Species And Of The Individual Are Equally Parts Of That Grand Sequence Of Events, Which Our Minds Refuse To Accept As The Result Of Blind Chance.

...he Who Remains Passive When Over-whelmed With Grief Loses His Best Chance Of Recovering His Elasticity Of Mind.

I Am Not Very Sceptical, — A Frame Of Mind Which I Believe To Be Injurious To The Progress Of Science. A Good Deal Of Scepticism In A Scientific Man Is Advisable To Avoid Much Loss Of Time, But I Have Met With Not A Few Men, Who, I Feel Sure, Have Often Thus Been Deterred From Experiment Or Observations, Which Would Have Proved Directly Or Indirectly Serviceable .

The Season Of Love Is That Of Battle. The Roots Of These Fights Run Deep.

...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.

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.

The Voyage Of The Beagle Has Been By Far The Most Important Event In My Life And Has Determined My Whole Career; Yet It Depended On So Small A Circumstance As My Uncle Offering To Drive Me 30 Miles To Shrewsbury, Which Few Uncles Would Have Done, And On Such A Trifle As The Shape Of My Nose.

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

The Lower Animals, On The Other Hand, Must Have Their Bodily Structure Modified In Order To Survive Under Greatly Changed Conditions. They Must Be Rendered Stronger, Or Acquire More Effective Teeth Or Claws, In Order To Defend Themselves From New Enemies; Or They Must Be Reduced In Size So As To Escape Detection And Danger. When They Migrate Into A Colder Climate They Must Become Clothed With Thicker Fur, Or Have Their Constitutions Altered. If They Fail To Be Thus Modified, They Will Cease To Exist.

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

We Are Always Slow In Admitting Any Great Change Of Which We Do Not See The Intermediate Steps

At Last Gleams Of Light Have Come, And I Am Almost Convinced (quite Contrary To Opinion I Started With) That Species Are Not (it Is Like Confessing A Murder) Immutable. Heaven Forfend Me From Lamarck Nonsense Of A 'tendency To Progression', 'adaptations From The Slow Willing Of Animals', &c! But The Conclusions I Am Led To Are Not Widely Different From His; Though The Means Of Change Are Wholly So. I Think I Have Found Out (here's Presumption!) The Simple Way By Which Species Become Exquisitely Adapted To Various Ends.

The School As A Means Of Education To Me Was Simply A Blank.

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

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

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.

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.

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?

Daily It Is Forced Home On The Mind Of The Biologist That Nothing, Not Even The Wind That Blows, Is So Unstable As The Level Of The Crust Of This Earth.

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.

I Have Deeply Regretted That I Did Not Proceed Far Enough At Least To Understand Something Of The Great Leading Principles Of Mathematics, For Men Thus Endowed Seem To Have An Extra Sense.

It Occurred To Me, In 1837, That Something Might Perhaps Be Made Of This Question (the Origin Of The Species) By Patiently Accumulating And Reflecting On All Sorts Of Facts Which Could Possibly Have Any Bearing On It

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.

I Am Aware That The Assumed Instinctive Belief In God Has Been Used By Many Persons As An Argument For His Existence. The Idea Of A Universal And Beneficent Creator Does Not Seem To Arise In The Mind Of Man, Until He Has Been Elevated By Long-continued Culture.

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.

Seeing Every Height Crowned With Its Crater, And The Boundaries Of Most Of The Lava-streams Still Distinct, We Are Led To Believe That Within A Period, Geologically Recent, The Unbroken Ocean Was Here Spread Out. Hence, Both In Space And Time, We Seem To Be Brought Somewhat Near To That Great Fact — That Mystery Of Mysteries — The First Appearance Of New Beings On This Earth.

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

I Often Had To Run Very Quickly To Be On Time, And From Being A Fleet Runner Was Generally Successful; But When In Doubt I Prayed Earnestly To God To Help Me, And I Well Remember That I Attributed My Success To The Prayers And Not To My Quick Running, And Marvelled How Generally I Was Aided.

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.

... 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.

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.

When It Was First Said That The Sun Stood Still And World Turned Round, The Common Sense Of Mankind Declared The Doctrine False; But The Old Saying Of Vox Populi, Vox Dei [the Voice Of The People Is The Voice Of God], As Every Philosopher Knows, Cannot Be Trusted In Science.

A Fair Result Can Be Obtained Only By Fully Stating And Balancing The Facts And Arguments On Both Sides Of Each Question." Charles Darwin

[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.

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.

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.

My Mind Seems To Have Become A Kind Of Machine For Grinding General Laws Out Of Large Collections Of Facts.

I Have Steadily Endeavored To Keep My Mind Free So As To Give Up Any Hypothesis, However Much Beloved (and I Cannot Resist Forming One On Every Subject), As Soon As The Facts Are Shown To Be Opposed To It.

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

Origin Of Species

It Is So Easy To Hide Our Ignorance Under Such Expressions As The Plan Of Creation Or Unity Of Design, Etc., And To Think That We Give An Explanation When We Only Restate A Fact.

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.

Whenever I Have Found That I Have Blundered, Or That My Work Has Been Imperfected, And When I Have Been Contemptuously Criticised, And Even When I Have Been Overpraised, So That I Have Felt Mortified, It Has Been My Greatest Comfort To Say Hundreds Of Times To Myself That 'i Have Worked As Hard As I Could, And No Man Can Do More Than This.'

The Expression Often Used By Mr. Herbert Spencer Of The Survival Of The Fittest Is More Accurate, And Is Sometimes Equally Convenient.

It Is Not The Strongest Of The Species That Survives, Nor The Most Intelligent That Survives. It Is The One That Is The Most Adaptable To Change, That Lives Within The Means Available And Works Co-operatively Against Common Threats.

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

...i Have Always Maintained That, Excepting Fools, Men Did Not Differ Much In Intellect, Only In Zeal And Hard Work; And I Still Think There Is An Eminently Important Difference.

We Cannot Fathom The Marvelous Complexity Of An Organic Being; But On The Hypothesis Here Advanced This Complexity Is Much Increased. Each Living Creature Must Be Looked At As A Microcosm--a Little Universe, Formed Of A Host Of Self-propagating Organisms, Inconceivably Minute And As Numerous As The Stars In Heaven.

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

The Assumed Instinctive Belief In God Has Been Used By Many Persons As An Argument For His Existence. But This Is A Rash Argument, As We Should Thus Be Compelled To Believe In The Existence Of Many Cruel And Malignant Spirits, Only A Little More Powerful Than Man; For The Belief In Them Is Far More General Than In A Beneficent Deity.

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.'

Although I Am Fully Convinced Of The Truth Of The Views Given In This Volume Under The Form Of An Abstract, I By No Means Expect To Convince Experienced Naturalists Whose Minds Are Stocked With A Multitude Of Facts All Viewed, During A Long Course Of Years, From A Point Of View Directly Opposite To Mine... I Look With Confidence To The Future, To Young And Rising Naturalists, Who Will Be Able To View Both Sides Of The Question With Impartiality.

Among The Scenes Which Are Deeply Impressed On My Mind, None Exceed In Sublimity The Primeval [tropical] Forests, ... Temples Filled With The Varied Productions Of The God Of Nature. No One Can Stand In These Solitudes Unmoved, And Not Feel That There Is More In Man Than The Mere Breath Of His Body.

With Highly Civilised Nations Continued Progress Depends In A Subordinate Degree On Natural Selection; For Such Nations Do Not Supplant And Exterminate One Another As Do Savage Tribes.

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

I Ought, Or I Ought Not, Constitute The Whole Of Morality.

Any One Whose Disposition Leads Him To Attach More Weight To Unexplained Difficulties Than To The Explanation Of Facts Will Certainly Reject My Theory.

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.

As Some Of The Lowest Organisms, In Which Nerves Cannot Be Detected, Are Capable Of Perceiving Light, It Does Not Seem Impossible That Certain Sensitive Elements In Their Sarcode Should Become Aggregated And Developed Into Nerves, Endowed With This Special Sensibility.

Englishmen Rarely Cry, Except Under The Pressure Of The Acutest Grief; Whereas In Some Parts Of The Continent The Men Shed Tears Much More Readily And Freely.

Hereafter We Shall Be Compelled To Acknowledge That The Only Distinction Between Species And Well-marked Varieties Is, That The Latter Are Known, Or Believed To Be Connected At The Present Day By Intermediate Gradations Whereas Species Were Formerly Thus Connected.

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

Your Words Have Come True With A Vengeance That I Shd [should] Be Forestalled ... I Never Saw A More Striking Coincidence. If Wallace Had My M.s. Sketch Written Out In 1842 He Could Not Have Made A Better Short Abstract! Even His Terms Now Stand As Heads Of My Chapters.

To My Deep Mortification My Father Once Said To Me, "you Care For Nothing But Shooting, Dogs, And Rat-catching, And You Will Be A Disgrace To Yourself And All Your Family."

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.

As Many More Individuals Of Each Species Are Born Than Can Possibly Survive; And As, Consequently, There Is A Frequently Recurring Struggle For Existence, It Follows That Any Being, If It Vary However Slightly In Any Manner Profitable To Itself, Under The Complex And Sometimes Varying Conditions Of Life, Will Have A Better Chance Of Surviving, And Thus Be Naturally Selected. From The Strong Principle Of Inheritance, Any Selected Variety Will Tend To Propagate Its New And Modified Form.

In The Struggle For Survival, The Fittest Win Out At The Expense Of Their Rivals Because They Succeed In Adapting Themselves Best To Their Environment.

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

We Feel Surprise When Travellers Tell Us Of The Vast Dimensions Of The Pyramids And Other Great Ruins, But How Utterly Insignificant Are The Greatest Of These, When Compared To These Mountains Of Stone Accumulated By The Agency Of Various Minute And Tender Animals!

Great Is The Power Of Steady Misrepresentation; But The History Of Science Shows That Fortunately This Power Does Not Long Endure.

The Impossibility Of Conceiving That This Grand And Wondrous Universe, With Our Conscious Selves, Arose Through Chance, Seems To Me The Chief Argument For  the Existence Of God.

I Shall Always Feel Respect For Every One Who Has Written A Book, Let It Be What It May, For I Had No Idea Of The Trouble Which Trying To Write Common English Could Cost One—and Alas There Yet Remains The Worst Part Of All Correcting The Press.

The Limit Of Man S Knowledge In Any Subject Possesses A High Interest Which Is Perhaps Increased By Its Close Neighbourhood To The Realms Of Imagination.

Every One Must Be Struck With Astonishment, When He First Beholds One Of These Vast Rings Of Coral-rock, Often Many Leagues In Diameter, Here And There Surmounted By A Low Verdant Island With Dazzling White Shores, Bathed On The Outside By The Foaming Breakers Of The Ocean, And On The Inside Surrounding A Calm Expanse Of Water, Which, From Reflection, Is Of A Bright But Pale Green Color.

In The Distant Future I See Open Fields For Far More Important Researches. Psychology Will Be Based On A New Foundation, That Of The Necessary Acquirement Of Each Mental Power And Capacity By Gradation. Light Will Be Thrown On The Origin Of Man And His History.

When I View All Beings Not As Special Creations, But As The Lineal Descendants Of Some Few Beings Which Lived Long Before The First Bed Of The Cambrian System Was Deposited, They Seem To Me To Become Ennobled.

Formerly Milton's Paradise Lost Had Been My Chief Favourite, And In My Excursions During The Voyage Of The Beagle, When I Could Take Only A Single Small Volume, I Always Chose Milton.

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.

Traveling Ought Also To Teach Him Distrust; But At The Same Time He Will Discover, How Many Truly Kind-hearted People There Are, With Whom He Never Before Had, Or Ever Again Will Have Any Further Communication, Who Yet Are Ready To Offer Him The Most Disinterested Assistance.

One General Law, Leading To The Advancement Of All Organic Beings, Namely, Multiply, Vary, Let The Strongest Live And The Weakest Die.

Origin Of Species

Man With All His Noble Qualities, With Sympathy Which Feels For The Most Debased, With Benevolence Which Extends Not Only To Other Men But To The Humblest Living Creature, With His God-like Intellect Which Has Penetrated Into The Movements And Constitution Of The Solar System- With All These Exalted Powers- Man Still Bears In His Bodily Frame The Indelible Stamp Of His Lowly Origin.

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

... Not One Living Species Will Transmit Its Unaltered Likeness To A Distant Futurity.

Origin Of Species

After Five Years' Work I Allowed Myself To Speculate On The Subject, And Drew Up Some Short Notes; These I Enlarged In 1844 Into A Sketch Of The Conclusions, Which Then Seemed To Me Probable: From That Period To The Present Day I Have Steadily Pursued The Same Object. I Hope That I May Be Excused For Entering On These Personal Details, As I Give Them To Show That I Have Not Been Hasty In Coming To A Decision.‎

I Am Sorry To Have To Inform You That I Do Not Believe In The Bible As A Divine Revelation, & Therefore Not In Jesus Christ As The Son Of God.

Such Simple Instincts As Bees Making A Beehive Could Be Sufficient To Overthrow My Whole Theory.

So In Regard To Mental Qualities, Their Transmission Is Manifest In Our Dogs, Horses And Other Domestic Animals. Besides Special Tastes And Habits, General Intelligence, Courage, Bad And Good Tempers. Etc., Are Certainly Transmitted.

I Could Show Fight On Natural Selection Having Done And Doing More For The Progress Of Civilization Than You Seem Inclined To Admit. Remember What Risk The Nations Of Europe Ran, Not So Many Centuries Ago Of Being Overwhelmed By The Turks, And How Ridiculous Such An Idea Now Is! The More Civilised So-called Caucasian Races Have Beaten The Turkish Hollow In The Struggle For Existence. Looking To The World At No Very Distant Date, What An Endless Number Of The Lower Races Will Have Been Eliminated By The Higher Civilized Races Throughout The World.

The Fact Of Evolution Is The Backbone Of Biology, And Biology Is Thus In The Peculiar Position Of Being A Science Founded On An Improved Theory, Is It Then A Science Or Faith?

Theory Of Evolution

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.

...one Doubts Existence Of Free Will [because] Every Action Determined By Heredity, Constitution, Example Of Others Or Teaching Of Others." "this View Should Teach One Profound Humility, One Deserves No Credit For Anything...nor Ought One To Blame Others.

From The First Dawn Of Life, All Organic Beings Are Found To Resemble Each Other In Descending Degrees, So That They Can Be Classed In Groups Under Groups. This Classification Is Evidently Not Arbitrary Like The Grouping Of Stars In Constellations.

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.

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.

Natural Selection Acts Solely By Accumulating Slight Successive Favorable Variations, It Can Produce No Great Or Sudden Modification; It Can Act Only By Very Short Steps.

Thus We Have Given To Man A Pedigree Of Prodigious Length, But Not, It May Be Said, Of Noble Quality.

From The War Of Nature, From Famine And Death, The Most Exalted Object Which We Are Capable Of Conceiving, Namely, The Production Of Higher Animals, Directly Follows.

The Most Important Factor In Survival Is Neither Intelligence Nor Strength But Adaptability.

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.

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

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!

I Am Quite Conscious That My Speculations Run Beyond The Bounds Of True Science....it Is A Mere Rag Of An Hypothesis With As Many Flaw[s] & Holes As Sound Parts.

The Highest Possible Stage In Moral Culture Is When We Recognize That We Ought To Control Our Thoughts.

[herschel And Humboldt] Stirred Up In Me A Burning Zeal To Add Even The Most Humble Contribution To The Noble Structure Of Natural Science. No One Or A Dozen Other Books Influenced Me Nearly So Much As These Two. I Copied Out From Humboldt Long Passages About Teneriffe And Read Them Aloud On One Of [my Walking Excursions].

I Always Make Special Notes About Evidence That Contridicts Me: Supportive Evidence I Can Remember Without Trying.

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

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.
