They say that Phidias, the celebrated statuary, made statues of brass, and of ivory, and of gold, and of other different materials, and that in all these works he displayed one and the same art, so that not only good judges, but even those who had no pretensions to the title, recognized the artist from his works.

For, as in the case of twins, nature having often employed the same character, has produced similitudes very slightly indeed differing from one another; in the same manner perfect art, being the imitation and copy of nature, when it has taken different materials, fashions and stamps the same appearance on all, so that the works produced by her are in the highest possible degree kindred, and brother-like, and twins.

And the power which exists in the wise man will show the same result: for when it is occupied with the affairs of the living God it is called piety and holiness: but when it employs itself upon the heaven, and the things in heaven, it is natural philosophy; and when it devotes itself to the investigation of the air, and of the different circumstances attending its variations and changes, whether taking place in the uniform yearly revolutions of the seasons, or in the partial periods of months and days, it is then called meteorology. It is called moral philosophy when it busies itself about the rectification of human morals; and this moral philosophy is divided into several subordinate species; that namely of politics, when occupied about state affairs; economy, when applied to the management of a household; when it is devoted to the subject of banquets and entertainments, it is then convivial philosophy. Again, that power which concerns itself about the government of men, is royal; that which is conversant with commands and prohibitions, is legislative.

For all these different powers the wise man of many names and many celebrities does truly contain within himself, namely, piety, holiness, natural philosophy, meteorology, moral philosophy, political knowledge, economy, royal power, legislative wisdom, and innumerable other faculties; and in every one of them he will be seen to wear one and the same appearance.
