correlation between law and peace

Let me quote the memorable words of Bertand Russell: Our own planet, in which philosophers are apt to take a parochial and excessive interest, was once too hot to suport life, and will in time be too cold. After ages during which the earth produced harmless trilobites and butterflies, evolution progressed to the point at which it generated Neros, Ganghis Khans, and Hitlers. This, however, is a passing nightmare; in time the earth will become again incapable of supporting life, and peace will return and peace will reign the earth.
