It Is A Fatal Fault To Reason

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.

The Most Important Factor In Survival Is Neither Intelligence Nor Strength But Adaptability.

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.

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.

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