[19] It would seem that those intemperate critics who have thought proper to revile Plotinus, the leader of the latter Platonists, have paid no attention to the testimony of Longinus concerning this most wonderful man, as preserved by Porphyry in his life of him. For Longinus there says, "that though he does not entirely accede to many of his hypotheses, yet he exceedingly admires and loves the form of his writing, the density of his conceptions, and the philosophic manner in which his questions are disposed." And in another place he says, "Plotinus, as it seems, has explained the Pythagoric and Platonic principles more clearly than those that were prior to him; for neither are the writings of Numenius, Cronius, Moderatus, and Thrasyllus, to be compared with those of Plotinus on this subject." After such a testimony as this from such a consummate critic as Longinus, the writings of Plotinus have nothing to fear from the imbecile censure of modern critics. I shall only further observe, that Longinus, in the above testimony, does not give the least hint of his having found any polluted streams, or corruption of the doctrines of Plato, in the works of Plotinus. There is not indeed the least vestige of his entertaining any such opinion in any part of what he has said about this most extraordinary man. This discovery was reserved for the more acute critic of modern times, who, by a happiness of conjecture unknown to the ancients, and the assistance of a good index, can in a few days penetrate the meaning of the profoundest writer of antiquity, and bid defiance even to the decision of Longinus. [20] Of this most divine man, who is justly said by the emperor Julian to have been posterior indeed in time, but not in genius even to Plato himself, see the life which I have given in the History of the Restoration of the Platonic Theology, in the second vol. of my Proclus on Euclid. ----------------------
