How do men behave without law? What is the only way to achieve peace?

...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.
