More From Charles Darwin

It Appears To Me (whether Rightly Or Wrongly) That Direct Arguments Against Christianity And Theism Produce Hardly Any Effect On The Public; And Freedom Of Thought Is Best Promoted By The Gradual Illumination Of Men's Minds, Which Follows From The Advance Of Science.

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!

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.

The Main Conclusion Here Arrived At ... Is That Man Is Descended From Some Less Highly Organized Form.

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.

Nothing Can Be More Improving To A Young Naturalist, Than A Journey In A Distant Country.

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.

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

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.

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.

Ignorance More Frequently Begets Confidence Than Does Knowledge.

A Cell Is A Complex Structure, With Its Investing Membrane, Nucleus, And Nucleolus.

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.

I Must Begin With A Good Body Of Facts And Not From A Principle (in Which I Always Suspect Some Fallacy) And Then As Much Deduction As You Please.

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

In The Survival Of Favoured Individuals And Races, During The Constantly-recurring Struggle For Existence, We See A Powerful And Ever-acting Form Of Selection.

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.

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.

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

[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].

If I Had Life To Live Over Again, I Would Give My Life To Poetry, To Music, To Literature, And To Art To Make Life Richer And Happier. In My Youth I Steeled Myself Against Them And Thought Them So Much Waste.

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.

The More One Thinks, The More One Feels The Hopeless Immensity Of Man's Ignorance.

A Celebrated Author And Divine Has Written To Me That He Has Gradually Learned To See That It Is Just As Noble A Conception Of The Deity To Believe That He Created A Few Original Forms Capable Of Self-development Into Other And Needful Forms, As To Believe That He Required A Fresh Act Of Creation To Supply The Voids Caused By The Action Of His Laws.

Only Picture To Yourself A Nice Soft Wife On A Sofa With Good Fire, & Books & Music.

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.

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

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...we Behold The Face Of Nature Bright With Gladness...we Do Not See, Or We Forget, That The Birds Which Are Idly Singing Round Us Mostly Live On Insects And Seeds, And Are Thus Constantly Destroying Life.

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

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.

Mere Chance ... Alone Would Never Account For So Habitual And Large An Amount Of Difference As That Between Varieties Of The Same Species.

Origin Of Species

Whoever Is Led To Believe That Species Are Mutable Will Do Good Service By Conscientiously Expressing His Conviction; For Only Thus Can The Load Of Prejudice By Which This Subject Is Overwhelmed Be Removed.

Not One Change Of Species Into Another Is On Record ... We Cannot Prove That A Single Species Has Been Changed.

Although Much Remains Obscure, And Will Long Remain Obscure, ... I Am Convinced That Natural Selection Has Been The Main But Not Exclusive Means Of Modification.

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

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.

I Am Not Apt To Follow Blindly The Lead Of Other Men

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.

The Young Blush Much More Freely Than The Old But Not During Infancy, Which Is Remarkable, As We Know That Infants At A Very Early Age Redden From Passion.

Light May Be Shed On Man And His Origins.

Each Organic Being Is Striving To Increase In A Geometrical Ratio . . . Each At Some Period Of Its Life, During Some Season Of The Year, During Each Generation Or At Intervals, Has To Struggle For Life And To Suffer Great Destruction . . . The Vigorous, The Healthy, And The Happy Survive And Multiply.

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

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."

Nature Will Tell You A Direct Lie If She Can.

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.‎

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?

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.

I Worked On True Baconian Principles, And Without Any Theory Collected Facts.

We Must, However, Acknowledge, As It Seems To Me, That Man With All His Noble Qualities... Still Bears In His Bodily Frame The Indelible Stamp Of His Lowly Origin.

Nothing Could Have Been Worse For The Development Of My Mind Than Dr. Butler's School, As It Was Strictly Classical, Nothing Else Being Taught, Except A Little Ancient Geography And History. The School As A Means Of Education To Me Was Simply A Blank. During My Whole Life I Have Been Singularly Incapable Of Mastering Any Language. Especial Attention Was Paid To Versemaking, And This I Could Never Do Well. I Had Many Friends, And Got Together A Good Collection Of Old Verses, Which By Patching Together, Sometimes Aided By Other Boys, I Could Work Into Any Subject.

The Normal Food Of Man Is Vegetable.

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 Cannot See ... Evidence Of Design And Beneficence ... There Seems To Me Too Much Misery In The World.

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.

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

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

And Hail Their Queen, Fair Regent Of The Night.

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

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.

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.

When The Sexes Differ In Beauty, In The Power Of Singing, Or In Producing What I Have Called Instrumental Music, It Is Almost Invariably The Male Which Excels The Female.

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.

Attention, If Sudden And Close, Graduates Into Surprise; And This Into Astonishment; And This Into Stupefied Amazement.

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.

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.

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

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 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!

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

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.

Till Facts Are Grouped & Called There Can Be No Prediction. The Only Advantage Of Discovering Laws Is To Foretell What Will Happen & To See Bearing Of Scattered Facts.

On Seeing The Marsupials In Australia For The First Time And Comparing Them To Placental Mammals: “an Unbeliever . . . Might Exclaim 'surely Two Distinct Creators Must Have Been At Work'”

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

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.

A Man's Friendships Are One Of The Best Measures Of His Worth.

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.

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.

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 Absurd To Talk Of One Animal Being Higher Than Another...we Consider Those, Where The Intellectual Faculties Most Developed As The Highest. - A Bee Doubtless Would [use] ... Instincts As A Criteria.

The Willing Horse Is Always Overworked.

Blushing Is The Most Peculiar And Most Human Of All Expressions.

[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.

I Have Been Speculating Last Night What Makes A Man A Discoverer Of Undiscovered Things. As Far As I Can Conjecture The Art Consists In Habitually Searching For The Causes And Meaning Of Everything Which Occurs.

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.

A Surprising Number [of Novels] Have Been Read Aloud To Me, And I Like All If Moderately Good, And If They Do Not End Unhappily-against Which A Law Ought To Be Passed.

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.

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.

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.

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.

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

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.

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.

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

What Can Be More Curious Than That The Hand Of A Man, Formed For Grasping, That Of A Mole For Digging, The Leg Of The Horse, The Paddle Of The Porpoise, And The Wing Of The Bat, Should All Be Constructed On The Same Pattern?

Hence, A Traveller Should Be A Botanist, For In All Views Plants Form The Chief Embellishment.

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

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.

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".

The Loss Of These Tastes [for Poetry And Music] Is A Loss Of Happiness, And May Possibly Be Injurious To The Intellect, And More Probably To The Moral Character, By Enfeebling The Emotional Part Of Our Nature.

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

In The Long History Of Humankind (and Animal Kind, Too) Those Who Learned To Collaborate And Improvise Most Effectively Have Prevailed.

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.

Intelligence Is Based On How Efficient A Species Became At Doing The Things They Need To Survive.

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.

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.

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.

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.

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.

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

If Every One Were Cast In The Same Mould, There Would Be No Such Thing As Beauty.

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.

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.

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'.

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!

I See No Good Reasons Why The Views Given In This Volume Should Shock The Religious Views Of Anyone.

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

I Think It Can Be Shown That There Is Such An Unerring Power At Work In Natural Selection, Which Selects Exclusively For The Good Of Each Organic Being.

Natural Selection

If I Had My Life To Live Over Again, I Would Have Made A Rule To Read Some Poetry And Listen To Some Music At Least Once Every Week.

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.

If Worms Have The Power Of Acquiring Some Notion, However Rude, Of The Shape Of An Object And Over Their Burrows, As Seems The Case, They Deserve To Be Called Intelligent; For They Act In Nearly The Same Manner As Would Man Under Similar Circumstances.

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.

When Primeval Man ﬁrst Used ﬂint Stones For Any Purpose, He Would Have Accidentally Splintered Them, And Would Then Have Used The Sharp Fragments. From This Step It Would Be A Small One To Break The ﬂints On Purpose And Not A Very Wide Step To Fashion Them Rudely.

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 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.

Music Was Known And Understood Before Words Were Spoken.

Man Is Descended From A Hairy, Tailed Quadruped, Probably Arboreal In Its Habits.

I Cannot Anyhow Be Contented To View This Wonderful Universe, And Especially The Nature Of Man, And To Conclude That Everything Is The Result Of Brute Force. I Am Inclined To Look At Everything As Resulting From Designed Laws, With The Details, Whether Good Or Bad, Left To The Working Out Of What We Call Chance. Not That This Notion At All Satisfies Me. 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 And Believe What He Can.

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.

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.

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?

It's An Awful Stretcher To Believe That A Peacock's Tail Was Thus Formed But ... Most People Just Don't Get It - I Must Be A Very Bad Explainer

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.

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.

The Tree Of Life Should Perhaps Be Called The Coral Of Life, Base Of Branches Dead; So That Passages Cannot Be Seen-this Again Offers Contradiction To Constant Succession Of Germs In Progress.

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

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

Much Love Much Trial, But What An Utter Desert Is Life Without Love.

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

Animals Manifestly Enjoy Excitement, And Suffer From Annul And May Exhibit Curiosity.

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.

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 .

A Bad Earthquake At Once Destroys The Oldest Associations: The World, The Very Emblem Of All That Is Solid, Has Moved Beneath Our Feet Like A Crust Over A Fluid; One Second Of Time Has Conveyed To The Mind A Strange Idea Of Insecurity, Which Hours Of Reflection Would Never Have Created.

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.

A Novel According To My Taste, Does Not Come Into The Moderately Good Class Unless It Contains Some Person Whom One Can Thoroughly Love - And If A Pretty Woman, All The Better.

From My Early Youth I Have Had The Strongest Desire To Understand Or Explain Whatever I Observed. ... To Group All Facts Under Some General Laws.

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.

Blushing Is The Most Peculiar And The Most Human Of All Expressions. Monkeys Redden From Passion, But It Would Require An Overwhelming Amount Of Evidence To Make Us Believe That Any Animal Could Blush.

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.

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.

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.

Some Call It Evolution, And Others Call It 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.

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.

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.

Looking To Future Generations, There Is No Cause To Fear That The Social Instincts Will Grow Weaker... The Social Instincts, - The Prime Principle Of Man's Moral Constitution - With The Aid Of Active Intellectual Powers And The Effects Of Habit, Naturally Lead To The Golden Rule, "as Ye Would That Men Should Do To You; Do Ye To Them Likewise"; And This Lies At The Foundation Of Morality.

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.

We Can Allow Satellites, Planets, Suns, Universe, Nay Whole Systems Of Universes, To Be Governed By Laws, But The Smallest Insect, We Wish To Be Created At Once By Special Act.

Theory Of Evolution

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.

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.

[alexander Von Humboldt Was The] Greatest Scientific Traveller Who Ever Lived.

In My Most Extreme Fluctuations I Have Never Been An Atheist In The Sense Of Denying The Existence Of A God ... I Think That Generally (& More And More So As I Grow Older) But Not Always, That An Agnostic Would Be The Most Correct Description Of My State Of Mind.

At Some Future Period, Not Very Distant As Measured By Centuries, The Civilized Races Of Man Will Almost Certainly Exterminate, And Replace The Savage Races Throughout The World.

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.

The Formation Of Different Languages And Of Distinct Species And The Proofs That Both Have Been Developed Through A Gradual Process, Are Curiously Parallel.

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.

Many Kinds Of Monkeys Have A Strong Taste For Tea, Coffee And Spirituous Liqueurs.

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.

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.

Every New Body Of Discovery Is Mathematical In Form, Because There Is No Other Guidance We Can Have.

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.

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.

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

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.

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.

The Mystery Of The Beginning Of All Things Is Insoluble By Us; And I For One Must Be Content To Remain An Agnostic.

Everything In Nature Is The Result Of Fixed Laws.

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.

There Is No Fundamental Difference Between Humans And The Higher Mammalsin Their Mental Faculties

I Cannot Persuade Myself That A Beneficent And Omnipotent God Would Have Designedly Created Parasitic Wasps With The Express Intention Of Their Feeding Within The Living Bodies Of Caterpillars.

I Have No Great Quickness Of Apprehension Or Wit Which Is So Remarkable In Some Clever Men, For Instance Huxley

The Moral Faculties Are Generally Esteemed, And With Justice, As Of Higher Value Than The Intellectual Powers. But We Should Always Bear In Mind That The Activity Of The Mind In Vividly Recalling Past Impressions Is One Of The Fundamental Though Secondary Bases Of Conscience. This Fact Affords The Strongest Argument For Educating And Stimulating In All Possible Ways The Intellectual Faculties Of Every Human Being.

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.

Owing To This Struggle For Life, Any Variation, However Slight And From Whatever Cause Proceeding, If It Be In Any Degree Profitable To An Individual Of Any Species, In Its Infinitely Complex Relationship To Other Organic Beings And To External Nature, Will Tend To The Preservation Of That Individual, And Will Generally Be Inherited By Its Offspring.

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.'

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

It Is Always Advisable To Perceive Clearly Our Ignorance.

I Have Long Discovered That Geologists Never Read Each Other's Works, And That The Only Object In Writing A Book Is A Proof Of Earnestness.
