"After Magna Carta became subject to renewed interest in the 17th century, William Blackstone referred to this provision as protecting the 'absolute rights of every Englishman'. And he formulated those absolute rights as 'the right of personal security', which included the right to life; 'the right of personal liberty'; and 'the right of private property'. He defined 'the right of personal liberty' as 'the power of loco-motion, 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'. The Framers drew heavily upon Blackstone's formulation, adopting provisions in early State Constitutions that replicated Magna Carta's language, but were modified to refer specifically to 'life, liberty, or property'. State decisions interpreting these provisions between the founding and the ratification of the Fourteenth Amendment almost uniformly construed the word 'liberty' to refer only to freedom from physical restraint. Even one case that has been identified as a possible exception to that view merely used broad language about liberty in the context of a habeas corpus proceeding—a proceeding classically associated with obtaining freedom from physical restraint."
