Till Facts Are Grouped & Called There

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.

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 Certain That There May Be Extraordinary Mental Activity With An Extremely Small Absolute Mass Of Nervous Matter: Thus The Wonderfully Diversified Instincts, Mental Powers, And Affections Of Ants Are Notorious, Yet Their Cerebral Ganglia Are Not So Large As The Quarter Of A Small Pin's Head. Under This Point Of View, The Brain Of An Ant Is One Of The Most Marvelous Atoms Of Matter In The World, Perhaps More So Than The Brain Of A Man.

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.

The Love For All Living Creatures Is The Most Noble Attribute Of Man.
