"There can be no successful government without the intimate, instinctive coordination of the organs of life and action. This is not theory, but fact, and displays its force as fact, whatever theories may be thrown across its track. Living political constitutions must be Darwinian in structure and in practice. Society is a living organism and must obey the laws of life, not of mechanics; it must develop. All that progressives ask or desire is permission—in an era when 'development,' 'evolution,' is the scientific word—to interpret the Constitution according to the Darwinian principle; all they ask is recognition of the fact that a nation is a living thing and not a machine."
