With a view to this desirable end, I have presented the reader with a specimen of that sublime wisdom which first arose in the colleges of the Egyptian priests, and flourished afterwards in Greece; which was there cultivated by Pythagoras, under the mysterious veil of numbers; by Plato, in the graceful dress of poetry; and was systematized by Aristotle, as far as it could be reduced into scientific order; which, after becoming in a manner extinct, shone again with its pristine splendour among the philosophers of the Alexandrian school; was learnedly illustrated with Asiatic luxuriancy of style by Proclus; was divinely explained by Iamblichus: and profoundly delivered in the writings of Plotinus. Indeed, the works of this last philosopher are particularly valuable to all who desire to penetrate into the depths of this divine wisdom. From the exalted nature of his genius, he was called Intellect by his contemporaries, and is said to have composed his books under the influence of divine illumination. Porphyry relates, in his life, that he was four times united by an ineffable energy with the divinity; which, however such an account may be ridiculed in the present age, will be credited by everyone who has properly explored the profundity of his mind. The facility and vehemence of his composition was such, that when he had once conceived a subject, he wrote as from an internal pattern, without paying much attention to the orthography, or reviewing what he had written; for the celestial vigour of his intellect rendered him incapable of trifling concerns, and in this respect, inferior to common understandings, as the eagle, which in its bold flight pierces the clouds, skims the surface of the earth with less rapidity than the swallow. Indeed a minute attention to trifles is inconsistent with great genius of every kind, and it is on this account that retirement is so absolutely necessary to the discovery of truths of the first dignity and importance; for how is it possible to mix much with the world, without imbibing the false and puerile conceptions of the multitude; and without losing that true elevation of soul which comparatively despises every mortal concern? Plotinus, therefore, conscious of the incorrectness of his writings arising from the rapidity, exuberance and daring sublimity of his thoughts, committed their revision to his disciple Porphyry; who, though inferior in depth of thought to his master, was, on account of his extraordinary abilities, called by way of eminence the Philosopher.
