In the Leviathan, Thomas Hobbes posits the creation of a commonwealth by means of a social contract, and as part of that contract, Hobbes theorizes the creation of the office of a sovereign authority, the occupant of which is to act as the representative of the constituted wills of the individual parties of the contract. Hobbes insists that it is not possible for this sovereign authority to commit an injustice against those who have granted him his privileged position. This essay will briefly sketch the reasons Hobbes offers in defense of his position, and critically evaluate his arguments in light of some common objections.
