It May Be Said That Natural Selection Is Daily And Hourly Scrutinizing, Throughout The World, Every Variation, Even The Slightest; Rejecting That Which Is Bad, Preserving And Adding Up All That Is Good; Silently And Insensibly Working, Wherever And Whenever Opportunity Offers, At The Improvement Of Each Organic Being In Relation To Its Organic And Inorganic Conditions Of Life.

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?

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.'

On The Theory Of Natural Selection We Can Clearly Understand The Full Meaning Of That Old Canon In Natural History, “natura Non Facit Saltum.” This Canon, If We Look Only To The Present Inhabitants Of The World, Is Not Strictly Correct, But If We Include All Those Of Past Times, It Must By My Theory Be Strictly True.

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.

At Some Future Period, Not Very Distant As Measured By Centuries, The Civilised Races Of Man Will Almost Certainly Exterminate And Replace Throughout The World The Savage Races. At The Same Time The Anthropomorphous Apes, As Professor Schaaffhausen Has Remarked, Will No Doubt Be Exterminated. The Break Will Then Be Rendered Wider, For It Will Intervene Between Man In A More Civilised State As We May Hope, Than The Caucasian And Some Ape As Low As A Baboon, Instead Of As At Present Between The Negro Or Australian And The Gorilla.

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.

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.

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

I Fully Agree With All That You Say On The Advantages Of Spencer's Excellent Expression Of 'the Survival Of The Fittest.' This, However, Had Not Occurred To Me Till Reading Your Letter. It Is, However, A Great Objection To This Term That It Cannot Be Used As A Substantive Governing A Verb; And That This Is A Real Objection I Infer From H. Spencer Continually Using The Words, Natural Selection.

I Could Show Fight On Natural Selection Having Done And Doing More For The Progress Of Civilization Than You Seem Inclined To Admit.

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.

My Mind Seems To Have Become A Kind Of Machine For Grinding General Laws Out Of Large Collections Of Facts, But Why This Should Have Caused The Atrophy Of That Part Of The Brain That Alone On Which The Higher Tastes Depend, I Cannot Conceive. A Man With A Mind More Highly Organised Or Better Constituted Than Mine Would Not, I Suppose, Have Thus Suffered, And If I Had To Live My Life Over Again, I Would Have Made A Rule To Read Some Poetry And Listen To Some Music At Least Once Every Week; For Perhaps The Parts Of My Brain Now Atrophied Would Thus Have Been Kept Alive Through Use.

I Am Not Very Sceptical, — A Frame Of Mind Which I Believe To Be Injurious To The Progress Of Science.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Nature Will Tell You A Direct Lie If She Can.

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.

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.

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.

But I Own That I Cannot See As Plainly As Others Do, And I Should Wish To Do, Evidence Of Design And Beneficence On All Sides Of Us. There Seems To Me Too Much Misery In The World.

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.

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?
