Life of Pythagoras — Iamblichus, trans. Thomas Taylor (1818)

1 Tamblichus here alludes to a right-angled triangle, and the Pythagoric theorem of 47. 1 of Euclid. For the square described on the longest side is equal to the two squares described on the two other sides. The longest side therefore is said by geometricians to be equal in power to the powers of the other sides.

This however Kiessling not understanding, says, ‘‘ that power is the space contained between the concurring lines of figures, and is the area of the triangle. “* Avvdpus idem est, quod éuBadov, spatium, quod intra concurrentes lineas figurarum continetur, area trigoni. But Kiessling, though a good verbalist, is a bad geometrician, and no philosopher.

96 to be unseasonable; but that of a younger with an elderly person is unseasonable. For no species of anger, or threatening, or boldness, is becoming in a younger towards an elderly man, but all unseasonable conduct of this kind should be cautiously avoided. A similar reasoning likewise should be adopted with respect to desert.

For it is neither decorous, nor seasonable, to use an unrestrained freedom of speech, or to adopt any of the above-mentioned modes of conduct, towards a man who has arrived at the true dignity of consummate virtue. Conformably to this also, was what he said respecting the association with parents, and likewise with benefactors. He added, that there is a certain various and multiform use of an opportune time.

For of those that are enraged and angry, some are so seasonably, but others unseasonably. And again, of those that aspire after, desire, and are impelled to any thing appetible, an opportune time is the attendant on some, and an unseasonable time on others. And the same thing may be said concerning other passions and actions, dispositions, associations, and meetings.

He further observed, that an opportune time is to a certain extent to be taught, and also, that what happens contrary to expectation, is capable of receiving an artificial discussion; but that when it is considered universally and simply, none of the above-mentioned particulars pertain toit.

Nearly, however, such things are the attendants on it, as follow the nature of opportune time, viz. what is called the florid, the becoming, the adapted, and whatever else there may be homogeneous to these. He likewise asserted, that principle for the beginning] is in the universe unity, and is the most honorable of things; and that in a similar manner it is so in science, in experience, and in generation.

And again, that the number two is most honorable in a house, in a city, in a camp, and in all such like systems. But that the nature of principle is difficult to be surveyed and apprehended in all the above-mentioned

particulars. For in sciences, it is not the province of any casual understanding to learn and judge, by well surveying the parts of things, what the nature is of the principle of these. He added, that it makes a great difference, and that there is danger with respect to the knowledge of the whole of things, when principle is not rightly assumed. For none, in short, of the consequent conclusions can be sane, when the true principle is unknown. The same thing may also be said respecting a principle of another kind. For neither can a house, nor a city, be well instituted, unless each has a true ruler, who governs those that voluntarily submit to him. For it is necessary that in both these the governor should be willing to rule, and the governed to obey. Just as with respect to disciplines, when they are taught with proper effect, it is necessary that there should be a concurrence in the will both of the teacher and learner. For if there is a resistance on the part of either, the proposed work will never be accomplished in a proper manner. ‘Thus therefore, he proved, that it was beautiful to be persuaded by rulers, and to be obedient to preceptors. But he exhibited the following as the greatest argument through deeds, of the truth of his observations. He went from Italy to Delos, to Pherecydes the Syrian, who had been his. preceptor, in order that he might afford him some assistance, as he was then afflicted with what is called the morbus pedicularis, and he carefully attended him to the time of his death, and piously performed whatever rites were due to his dead preceptor. So diligent was he in the discharge of his duties to him from whom he had received instruction.
