Famous quotes containing the words evolution and/or organization:
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
“The Red Cross in its nature, it aims and purposes, and consequently, its methods, is unlike any other organization in the country. It is an organization of physical action, of instantaneous action, at the spur of the moment; it cannot await the ordinary deliberation of organized bodies if it would be of use to suffering humanity, ... [ellipsis in original] it has by its nature a field of its own.”
—Clara Barton (1821–1912)
