No other teacher has ever been loved and reverenced by his scholars as much as Epicurus; they lived on such intimate terms of friendship that they determined to make common stock of their possessions with him, and so continue in a permanent association, like a kind of Pythagorean brotherhood. This they were, however, forbidden to do by Epicurus himself, because it would have betrayed a distrust in their readiness to share what they had with one another; but where distrust is possible, there neither friendship, nor unity, nor constancy of attachment can find a place. After his death he was held in honoured remembrance by his disciples: they carried about with them everywhere his likeness, engraved on rings or drinking-cups, and remained so faithful to his teaching that they considered it almost a crime to make any alteration in it (while in the Stoic philosophy development was continually going on), and his school, in respect of his doctrines, resembled a closely-barricaded state to which all entrance was denied. The reason for this lies, as we shall presently see, in his system itself; and the further result, from a scientific point of view, ensued that we can name no celebrated disciples of his who carried on and completed his teaching on their own account. For his disciples could only have gained distinction for themselves by going further than Epicurus did. But to go further would have been to reach the Notion, which would only have confused the system of Epicurus; for what is devoid of thought is thrown into confusion by the introduction of the Notion, and it is this very lack of thought which has been made a principle. Not that it is in itself without thought, but the use made of thought is to hold back thought, and thought thus takes up a negative position in regard to itself; and the philosophic activity of Epicurus is thus directed towards the restoration and maintaining of what is sensuous through the very Notion which renders it confused. Therefore his philosophy has not advanced nor developed, but it must also be said that it has not retrograded; a certain Metrodorus alone is said to have carried it on further in some directions. It is also told to the credit of the Epicurean philosophy that this Metrodorus was the only disciple of Epicurus who went over to Carneades; for the rest, it surpassed all others in its unbroken continuity of doctrine and its long duration; for all of them became degenerate or suffered interruption. When some one called the attention of Arcesilaus to this attachment to Epicurus, by the remark that while so many had gone over from other philosophers to Epicurus, scarcely a single example was known of any one passing over from the Epicurean system to another, Arcesilaus made the witty rejoinder: “Men may become eunuchs, but eunuchs can never again become men.”[146]
