First, then, we must consider what is the function of kings; for if we can properly encompass the essence of the whole matter in a general principle For the habit of definition in Isocrates see General Introd. p. xvii. we shall, with this before us, speak to better purpose about its parts. I think that all would agree that it is a king’s business to relieve the state when it is in distress, to maintain it in prosperity, and to make it great when it is small; for it is with these ends in view that the other duties which present themselves day by day must be performed. And surely this much is clear, that those who are able to do all this, and who pronounce on matters of so great moment, must not be indolent nor careless, but must see to it that they are superior to all others in intelligence; for it is evident that they will reign well or ill according to the manner in which they equip their own minds. Cf. Isoc. 9.41 .
