What is bellum omni contra omnes?

Bellum omni contra omnes, also known as "war of all against all," is a philosophical concept introduced by Thomas Hobbes in his book, Leviathan. The concept describes a hypothetical state of nature in which human beings would constantly be in a state of conflict with one another due to a lack of government or social structure. Hobbes argued that a strong central government was necessary to prevent such a state of perpetual conflict and ensure societal order. The idea has become a foundational concept in political philosophy and continues to be debated and discussed by scholars today.
