The condition in which people give up some individual liberty in exchange for some common security is the Social Contract. Hobbes defines contract as the mutual transferring of right.. In the state of nature, everyone has the right to everything - there are no limits to the right of natural liberty.

Hobbes believed that all phenomena in the universe, without exception, can be explained in terms of the motions and interactions of material bodies. He did not believe in the soul, or in the mind as separate from the body, or in any of the other incorporeal and metaphysical entities in which other writers have believed.
