some background info here
“After the outbreak of the Civil War in 1642, Hobbes set aside work on the Elements of Philosophy as such, and conceived instead a single-volume work, which would start with a very brief summary of his metaphysics (in effect, On Body without the scientific material); then continue with a fuller summary of On the Human Being; and the bulk of the work would be an expanded version of On the Citizen. It was published, in English, in 1651, with the rather contentious title Leviathan.”
