The condition of man... is a condition of war of everyone against everyone.

During the time men live without a common power to keep them all in awe, they are in that conditions called war; and such a war, as if of every man, against every man.

When all the world is overcharged with inhabitants, then the last remedy of all is war, which provideth for every man, by victory or death.

The condition of man . . . is a condition of war of everyone against everyone.

Felicity is a continual progress of the desire, from one object to another; the attaining of the former being still but the way to the latter.

So that in the nature of man,
we find three principal causes of quarrel:

First, Competition;
Secondly, Dissidence;
Thirdly, Glory.

The first, maketh men invade for Gain;
the second, for Safety;
and the third, for Reputation.

The first use Violence, to make themselves Masters of other men's persons, wives, children and cattle;
the second, to defend them;
the third, for trifles, as a word, a smile, a different opinion, and any other sign of undervalue, either direct in their Persons, or by reflexion in their Kindred, their Friends, their Nation, their Profession, or their Name.
