Nor are ideas according to these men notions, as Cleanthes afterwards asserted them to be. Nor is idea definite reason, nor material form; for these subsist in composition and division, and verge to matter. But ideas are perfect, simple, immaterial, and impartible natures. And what wonder is there, says Syrianus, if we should separate things which are so much distant from each other? Since neither do we imitate in this particular Plutarch, Atticus, and Democritus, who, because universal reasons perpetually subsist in the essence of the soul, were of opinion that these reasons are ideas: for though they separate them from the universal in sensible natures, yet it is not proper to conjoin in one and the same the reason of soul, and an intellect such as ours, with paradigmatic and immaterial forms, and demiurgic intellections. But as the divine Plato says, it is the province of our soul to collect things into one by a reasoning process, and to possess a reminiscence of those transcendent spectacles, which we once beheld when governing the universe in conjunction with divinity. Boethus,[13] the peripatetic too, with whom it is proper to join Cornutus; thought that ideas are the same with universals in sensible natures. However, whether these universals are prior to particulars, they are not prior in such a manner as to be denudated from the habitude which they possess with respect to them, nor do they subsist as the causes of particulars; both which are the prerogatives of ideas; or whether they are posterior to particulars, as many are accustomed to call them, how can things of posterior origin, which have no essential subsistence, but are nothing more than slender conceptions, sustain the dignity of fabricative ideas? ------------------- [13] This was a Greek philosopher, who is often cited by Simplicius in his Commentary on the Predicaments, and must not therefore be confounded with Boetius, the roman senator and philosopher. ------------------- In what manner then, says Syrianus, do ideas subsist according to the contemplative lovers of truth? We reply, intelligibly and tetradically ([Greek: noeros kai tetradikos]), in animal itself ([Greek: en to antozoo]), or the extremity of the intelligible order; but intellectually and decadically ([Greek: noeros kai dekadikos]), in the intellect of the artificer of the universe; for, according to the Pythagoric Hymn, "Divine number proceeds from the retreats of the undecaying monad, till it arrives at the divine tetrad which produced the mother of all things, the universal recipient, venerable, circularly investing all things with bound, immovable and unwearied, and which is denominated the sacred decad, both by the immortal gods and earth-born men."
