Nature (the Art whereby God hath made and governes the World) is by the Art of man, as in many other things, so in this also imitated, that it can make an Artificial Animal. For seeing life is but a motion of Limbs, the beginning whereof is in some principall part within, why may we not say, that all Automata (Engines that move themselves by springs and wheeles as doth a watch) have an artificiall life? For what is the Heart, but a Spring; and the Nerves, but so many Strings; and the Joynts, but so many Wheeles, giving motion to the whole Body, such as was intended by the Artificer? Art goes yet further, imitating that Rationall and most excellent worke of Nature, Man. For by Art is created that great Leviathan called a Common-wealth, or State, (in latine Civitas) which is but an Artificiall Man; though of greater stature and strength than the Naturall, for whose protection and defence it was intended; and in which, the Soveraignty is an Artificiall Soul, as giving life and motion to the whole body.... p.9

I. The faculties of Humane nature may be reduc'd unto four kinds; Bodily strength, Experience, Reason, Passion. Taking the beginning of this following Doctrine from these, we will declare in the first place what manner of inclinations men who are endued with these faculties bare towards each other, and whether, and by what faculty, they are born apt for Society, and so preserve themselves against mutuall violence; then proceeding, we will shew what advice was necessary to be taken for this businesse, and what are the conditions of Society, or of Humane Peace; that is to say, (changing the words onely) what are the fundamentall Lawes of Nature.
