ABSTRACT
The effect was truly tremendous. Almost by the mere statement of a new principle of approach, dynamic not static, he revolutionized every department of study, from astronomy to history, from palaeontology to psychology, from embryology to religion. Dr. Charles Singer’s remark that “ the whole of modem biology has been called a commentary on The Origin of Species ” has in essence a much wider application. The intellectual fer mentation begun by Darwin’s work has increased rather than diminished its activity with each subsequent decade. To-day it is almost impossible for us to return, even momentarily, to the pre-Darwinian atmosphere and attitude. The evolutionary conception is the oxygen in the air we breathe; it has woven itself into the very fibre of our thought; it shapes the world we see before our eyes, one in which permanent stability is unknown, in which life is change and change is life. Our interest is not in
being but becoming, in process, and what is everywhere looked for is everywhere discovered.
