The view of mobility and liberty in Hobbes is replicated two hundred years later by William Blackstone, who argued that law is derived from a heady mixture of God and physics. The most important principles of matter, he argued, are the “laws of movement, to which all moveable bodies must conform.” Mobility, he argued, was an absolute right of man. The right to personal liberty he defined as the power of “loco-movement” or the ability of “changing situation, or removing one’s person to whatsoever place one’s own inclination may direct; without imprisonment or restraint, unless by due course of law.”
