The difficulty inherent in judging the validity of claims to power by men who claim to be acting upon the "secret" will of God was disregarded by Filmer, who held that it altered in no way the nature of such power, based on the natural right of a supreme father to hold sway.

He cannot be bound by the acts of his predecessors, for which he is not responsible; nor by his own, for it is impossible that a man should give a law to himself – a law must be imposed by another upon the person bound by it.
