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.

To this war of every man against every man, this also in consequent; that nothing can be unjust. The notions of right and wrong, justice and injustice have there no place. Where there is no common power, there is no law, where no law, no injustice. Force, and fraud, are in war the cardinal virtues.

No arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death: and the life of man, solitary, poor, nasty, brutish and short.

- Hobbes
