Gregory of Nyssa on the Metaphysics of the Trinity (with Reference to his Letter To Ablabius)
This chapter explores Gregory’s metaphysics of the Trinity, which used an innovative distinction between stuffs (e.g. gold), which cannot be counted, and individuals (e.g. rings), which can. Gregory identifies the nature of any kind with the totality of its instances: the nature of man is the totality of men; the nature of gold is the totality of gold. For Gregory, the totality is more ‘real’ than the individuals into which it is articulated, which are merely the way in which the kind is present in the world. God is then identified as the total quantity of divinity in the world, and is thus one, and real. The Persons of the Trinity into which God is articulated are the ways God is in the world, and can be comprehended by us. Thus, the problem of the Trinity is solved as a special case of the philosophical problem of the One and Many.
