Bellum omnium contra omnes

Bellum omnium contra omnes, a Latin phrase meaning "the war of all against all", is the description that Thomas Hobbes gives to human existence in the state-of-nature thought experiment that he conducts in De Cive (1642) and Leviathan (1651).

[15] [...] In such condition there is no place for Industry, because the fruit thereof is uncertain: and consequently no Culture of the Earth; no Navigation, nor use of the commodities that may be imported by Sea; no commodious Building; no Instruments of moving and removing such things as require much force; no Knowledge of the face of the Earth; no account of Time; 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.

[18] The phrase was sometimes used by Karl Marx and Friedrich Engels: Religion has become the spirit of civil society, of the sphere of egoism, of bellum omnium contra omnes.

When this conjurer's trick has been performed..., the same theories are transferred back again from organic nature into history and it is now claimed that their validity as eternal laws of human society has been proved.

But because man, out of need and boredom, wants to exist socially, herd-fashion, he requires a peace pact and he endeavors to banish at least the very crudest bellum omnium contra omnes from his world.
