In place of ruthless selfassertion it demands self-restraint; in place of thrusting aside, or treading down, all competitors, it requires that the individual shall not merely respect , but shall help his fellows. It repudiates the gladiatorial theory of existence. Laws and moral precepts are directed to the end of curbing the cosmic process.
