Ens Rationis
(in Scholasticism) A purelv objective ens rationis is a chimera, or an impossible thing, although in a certain way it is an object of human knowledge, as a triangular circle. A logical ens rationis is that which is fashioned by the intellect with some foundation in realitv, e.g. human nature conceived as one reality because of the likeness of singular natures. — H.G.
