If any two men desire the same thing, which nevertheless they cannot both enjoy, they become enemies; and in the way to their end… endeavor to destroy or subdue one another. And from hence it comes to pass that where an invader hath no more to fear than another man's single power, if one plant, sow, build, or possess a con-venient seat, others may probably be expected to come prepared with forces unit-ed to dispossess and deprive him, not only of the fruit of his labor, but also of his life or liberty. And the invader again is in the like danger of another. …From this fundamental law of nature, by which men are commanded to endeavor peace, is derived this second law: that a man be willing, when others are so too, as far forth as for peace and defense of himself he shall think it necessary, to lay down this right to all things; and be contented with so much liberty against other men as would allow other men against himself.
… The mutual transferring of rights is that which men call [social] contract.
