According to Hobbes, self-preservation is man's predominant desire. People are forced to cooperate with each other when their survival is at stake. Hobbes recognizes that although some men may be physically stronger than others, "the weaker has strength enough to kill the stronger, either by secret machination, or by confederation with others who are in the same danger as himself” (Hobbes, 158). Weaker men must band together to defeat stronger men in order to preserve their own lives. People want to live comfortably and don't want to die. Such desires, according to Hobbes, are driving forces for peace and help maintain some sort of order within the state.
