[It is not these three together that constitute the one substance. The mind alone is the substance—the knowledge and the love being only two activities of it. When the mind is not cognizing or loving, it is still an entire mind. As previously remarked in the annotation on IX. ii. this ternary will completely illustrate a trinality of a certain kind, but not that of the Trinity; in which the “tria quædam” are three subsistences, each of which is so substantial as to be the subject of attributes, and to be able to employ them. The human mind is substantial enough to possess and employ the attributes of knowledge and love. We say that the mind knows and loves. But an activity of the mind is not substantial enough to possess and employ the attributes of knowledge and love. We cannot say that the loving loves; or the loving knows; or the knowing loves, etc.—W.G.T.S.]
