Fact I Know; And Law I Know;

It Is An Error To Imagine That Evolution Signifies A Constant Tendency To Increased Perfection. That Process Undoubtedly Involves A Constant Remodeling Of The Organism In Adaptation To New Conditions; But It Depends On The Nature Of Those Conditions Whether The Direction Of The Modifications Effected Shall Be Upward Or Downward.

In Truth, The Laboratory Is The Forecourt Of The Temple Of Philosophy, And Whoso Has Not Offered Sacrifices And Undergone Purification There Has Little Chance Of Admission Into The Sanctuary.

The Facts Of Variability, Of The Struggle For Existence, Of Adaptation To Conditions, Were Notorious Enough; But None Of Us Had Suspected That The Road To The Heart Of The Species Problem Lay Through Them, Until Darwin And Wallace Dispelled The Darkness.

I Believe That History Might Be, And Ought To Be, Taught In A New Fashion So As To Make The Meaning Of It As A Process Of Evolution Intelligible To The Young.

The Question Of All Questions For Humanity, The Problem Which Lies Behind All Others And Is More Interesting Than Any Of Them, Is That Of The Determination Of Man's Place In Nature And His Relation To The Cosmos.
