The laws of Nature oblige in foro interno ; that is to say, they bind to a desire they should take place: but in foro externo ; that is, to the putting them in act, not always. For he that should be modest, and tractable, and perform all he promises, in such time and place where no man else should do so, should but make himself a prey to others, and procure his own certain ruin, contrary to the ground of all laws of Nature, which tend to Nature’s preservation. And again, he that having sufficient security, that others shall observe the same laws towards him, observes them not himself, seeketh not peace, but war; and consequently the destruction of his nature by violence.
