The first, and also the most important, representative of New Platonism, is _Plotinus_. He was a pupil of Ammonius Saccas, who taught the Platonic philosophy at Alexandria in the beginning of the third century, though he left no writings behind him. Plotinus (A. D. 205-270) from his fortieth year taught philosophy at Rome. His opinions are contained in a course of hastily written and not closely connected treatises, which, after his death, were collected and published in six enneads by _Porphyry_ (who was born A. D. 233, and taught both philosophy and eloquence at Rome), his most noted disciple. From Rome and Alexandria, the New Platonism of Plotinus passed over in the fourth century to Athens, where it established itself in the Academy. In the fourth century, _Jamblichus_, a scholar of Porphyry, and in the fifth, Proclus, (412-485), were prominently distinguished among the New Platonists. With the triumph of Christianity and the consequent fall of heathenism, in the course of the sixth century, even this last bloom of Grecian philosophy faded away.
The common characteristic of all the New Platonists is a tendency to mysticism, theosophy, and theurgy. The majority of them gave themselves up to magic and sorcery, and the most distinguished boasted that they were the subjects of divine inspiration and illumination, able to look into the future, and to work miracles. They professed to be hierophants as much as philosophers, and exhibited the unmistakable tendency to represent a Pagan copy of Christianity, which should be at the same time a philosophy and a universal religion. In the following sketch of New Platonism we follow mainly the track of Plotinus.
1. ECSTASY AS A SUBJECTIVE STATE.—The result of the philosophical strivings antecedent to New Platonism had been Scepticism; which, seeing the impracticability of both the Stoic and Epicurean wisdom, had assumed a totally negative relation to every positive and theoretical content. But the end which Scepticism had actually gained was the opposite of that for which it had striven. It had striven for the perfect apathy of the sage, but it had gained only the necessity of incessantly opposing every positive affirmation. Instead of the rest which they had sought, they found rather an absolute unrest. This absolute unrest of the consciousness striving after an absolute rest, begat immediately a longing to be freed from this unrest, a longing after some content which should be absolutely satisfying, and stripped of every sceptical objection. This longing after an absolutely true, found its historical expression in New Platonism. The subject sought to master and comprehend the absolute; and this, neither by objective knowledge nor dialectic mediation, but immediately, by an inner and mystical mounting up of the subject in the form of an immediate beholding, or ecstasy. The knowledge of the true, says Plotinus, is not gained by proof nor by any mediation; it cannot be found when the objects known remain separate from the subject knowing, but only when the distinction between knower and known disappears; it is a beholding of the reason in itself, not in the sense that we see the reason, but the reason beholds itself; in no other way can knowledge come. If any one has attained to such a beholding, to such a true unison with the divine, he will despise the pure thinking which he otherwise loved, for this thinking was only a movement which presupposed a difference between the perceiver and the perceived. This mystical absorption into the Deity, or, the One, this resolving the self into the absolute, is that which gives to New Platonism a character so peculiarly distinct from the genuine Grecian systems of philosophy.
