The End of Commonwealth, particular Security:
Chap. 13
The finall Cause, End, or Designe of men, (who naturally love Liberty, and Dominion over others,) in the introduction of that restraint upon themselves, (in which wee see them live in Commonwealths,) is the foresight of their own preservation, and of a more contented life thereby; that is to say, of getting themselves out from that miserable condition of Warre, which is necessarily consequent (as hath been shewn) to the naturall Passions of men, when there is no visible Power to keep them in awe, and tye them by feare of punishment to the performance of their Covenants, and observation of those Lawes of Nature set down in the fourteenth and fifteenth Chapters.
What is not to be had from the Law of Nature:
For the Lawes of Nature (as Justice, Equity, Modesty, Mercy, and (in summe) doing to others, as wee would be done to,) of themselves, without the terrour of some Power, to cause them to be observed, are contrary to our naturall Passions, that carry us to Partiality, Pride, Revenge, and the like. And Covenants, without the Sword, are but Words, and of no strength to secure a man at all. Therefore notwithstanding the Lawes of Nature, (which every one hath then kept, when he has the will to keep them, when he can do it safely,) if there be no Power erected, or not great enough for our security; every man will, and may lawfully rely on his own strength and art, for caution against all other men.
