It May Be Doubted Whether Any Character

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

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.

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.

History Shows That The Human Mind, Fed By Constant Accessions Of Knowledge, Periodically Grows Too Large For Its Theoretical Coverings, And Bursts Them Asunder To Appear In New Habiliments, As The Feeding And Growing Grub, At Intervals, Casts Its Too Narrow Skin And Assumes Another.

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.
