Being’ (τὸ ὄν) as said of predicates in the critical text of Aristotle, Metaphysics Lambda

In this paper, I will be focusing on seeming anomalies in the use of the verb “to be,” as found in several passages in Metaphysics Lambda, once it is restored in a critical edition. At least a couple of times (4. 1070b25 and 7. 1072a25f.), instead of the standard subject agreement, the participle “being” shows agreement with the predicate noun. Such a peculiar feature is clearly attested in the most ancient textual witnesses, but was corrected in later Byzantine manuscripts and regarded as scribal mistakes by editors in the 19th and 20th century. In fact, the matter deserves close scrutiny.
