Light Will Be Thrown On The Origin

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.'

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.

With Savages, The Weak In Body Or Mind Are Soon Eliminated. We Civilized Men, On The Other Hand, Do Our Utmost To Check The Process Of Elimination. We Build Asylums For The Imbecile, The Maimed And The Sick. Thus The Weak Members Of Civilized Societies Propagate Their Kind. No One Who Has Attended To The Breeding Of Domestic Animals Will Doubt That This Must Be Highly Injurious To The Race Of Man. Hardly Anyone Is So Ignorant As To Allow His Worst Animals To Breed.

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 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.
