Plotinos: Complete Works, v. 3 In Chronological Order,...

Intelligence is thinking essence, a composite of all genera, and not a single genus. Veritable Intelligence is indeed essence connected with all things; consequently it is all essence. As to essence considered alone, it constitutes a genus, and is an element of Intelligence. Last, justice, temperance, and in general all the virtues are so many actualizations of Intelligence. They could not, therefore, rank amidst the primary genera. They are posterior to a genus, and constitute species.
