Abstract

As a metaphysic of human persons, constitutionalism in its most general form is the view that human persons are constituted by their bodies, but are not strictly identical to them. The relation between human persons and their bodies is that of constitution, a type of unity relation whose relata are strictly nonidentical; “constitution is not identity”, as the phrase goes. As the literature on constitutionalism is plentiful the proponents and critics of the view are many the author will interact principally (though not exclusively) with the brand of constitutionalism defended by Lynne Rudder Baker. Constitutionalism runs afoul of an independently plausible principle regarding the relationship between persons and their mental lives, what Andrew Bailey has called the priority principle. The principal motivating factor behind the priority principle is that human persons are the ultimate source or originator of their mental lives.
