"...I will argue, in the third volume of this study, that analogy is intimately connected with the essence of one: one is a kind of analogy. As such, one is distinct from being. Importantly, in Aristotle's considered opinion, as we learn late in the Metaphysics (N 6), an analogy has little ontological status and is not the sort of unity that can be the object of knowledge. In contrast, being can be known and be the object of the science of metaphysics because it is a pros hen. The failure to appreciate the difference, spurred unfortunately by Aquinas's pros hen analogy, has contributed to the widespread supposition that one and being are effectively identical." Halper 2009, p.145.
Yanarras, Person and Eros, ch. 3, Analogy and Hierarchy, has a good discussion of the history of analogy in Aristotle and Plato, the scholastics, and analogy in Dionysius and his view of the Eastern tradition.
