Philo Judaeus De Ebrietate 91

[91] 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.
