[18]See the 7th Epistle of Plato.
[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. ———————————
As to the style of Porphyry, when we consider that he was the disciple of Longinus, whom Eunapius elegantly calls "a certain living library, and walking museum," it is but reasonable to suppose that he imbibed some portion of his master's excellence in writing. That he did so is abundantly evident from the testimony of Eunapius, who particularly commends his style for its clearness, purity, and grace. "Hence," he says, "Porphyry being let down to men like a mercurial chain, through his various erudition, unfolded every thing into perspicuity, and purity." And in another place he speaks of him as abounding with all the graces of diction, and as the only one that exhibited and proclaimed the praise of his master. With respect to the style of Proclus, it is pure, clear and elegant, like that of Dionysius Halicarnassus; but is much more copious and magnificent; that of Hierocles is venerable and majestic, and nearly equals the style of the greatest ancients; that of Sallust possesses an accuracy and a pregnant brevity, which cannot easily be distinguished from the composition of the Stagirite; and lastly, that of Damascius is clear and accurate, and highly worthy a most investigating mind.
Others again have filled themselves with a vain confidence, from reading of commentaries of these admirable interpreters, and have in a short time considered themselves superior to their masters. This was the case with Ficinus, Picus, Dr. Henry Moore, and other pseudo Platonists, their contemporaries, who, in order to combine Christianity with the doctrines of Plato, rejected some of his most important tenets, and perverted others, and thus corrupted one of these systems, and afforded no real benefit to the other.
But who are the men by whom these latter interpreters of Plato are reviled? When and whence did this defamation originate? Was it when the fierce champions for the trinity fled from Galilee to the groves of Academus, and invoked, but in vain, the assistance of Philosophy? When
The trembling grove confessed its fright,
The wood-nymphs started at the sight;
Ilissus backward urg'd his course,
And rush'd indignant to his source.
Was it because that mitred sophist, Warburton, thought fit to talk of the polluted streams of the Alexandrian school, without knowing any thing of the source whence those streams are derived? Or was it because some heavy German critic, who knew nothing beyond a verb in mi, presumed to grunt at these venerable heroes? Whatever was its source, and whenever it originated, for I have not been able to discover either, this however is certain, that it owes its being to the most profound Ignorance, or the most artful Sophistry, and that its origin is no less contemptible than obscure. For let us but for a moment consider the advantages which these latter Platonists possessed beyond any of their modern revilers. In the first place, they had the felicity of having the Greek for their native language, and must therefore, as they were confessedly, learned men, have understood that language incomparably better than any man since the time in which the ancient Greek was a living tongue. In the next place, they had books to consult, written by the immediate disciples of Plato, which have been lost for upwards of a thousand years, besides many Pythagoric writings from which Plato himself derived most of his more sublime dogmas. Hence we find the works of Parmenides, Empedocles, the Electic Zeno, Speusippus, Xenocrates, and many other illustrious philosophers of the highest antiquity, who were either genuine Platonists or the sources of Platonism, are continually cited by these most excellent interpreters, and in the third place they united the greatest purity of life to the most piercing vigor of intellect. Now when it is considered that the philosophy to the study of which these great men devoted their lives, was professedly delivered by its author in obscurity; that Aristotle himself studied it for twenty years; and that it was no uncommon thing, as Plato informs us in one of his Epistles, to find students unable to comprehend its sublimest tenets even in a longer period than this,—when all these circumstances are considered, what must we think of the arrogance, not to say impudence, of men in the seventeenth, eighteenth, and nineteenth centuries, who have dared to calumniate these great masters of wisdom? Of men, with whom the Greek is no native language; who have no such books to consult as those had whom they revile; who have never thought, even in a dream, of making the acquisition of wisdom the great object of their life; and who in short have committed that most baneful error of mistaking philology for philosophy, and words for things? When such as these dare to defame men who may be justly ranked among the greatest and wisest of the ancients, what else can be said than that they are the legitimate descendants of the suitors of Penelope, whom, in the animated language of Ulysses,
Laws or divine or human fail'd to move,
Or shame of men, or dread of gods above:
Heedless alike of infamy or praise,
Or Fame's eternal voice in future days,[21]
