From Sextus, a benevolent disposition, and the example of a family governed in a fatherly manner, and the idea of living conformably to nature; and gravity without affectation, and to look carefully after the interests of friends, and to tolerate ignorant persons, and those who form opinions without consideration: he had the power of readily accommodating himself to all, so that intercourse with him was more agreeable than any flattery; and at the same time he was most highly venerated by those who associated with him: and he had the faculty both of discovering and ordering, in an intelligent and methodical way, the principles necessary for life; and he never showed anger or any other passion, but was entirely free from passion, and also most affectionate; and he could express approbation without noisy display, and he possessed much knowledge without ostentation.
That which rules within, when it is according to nature, is so affected with respect to the events which happen, that it always easily adapts itself to that which is and is presented to it. For it requires no definite material, but it moves towards its purpose, under certain conditions however; and it makes a material for itself out of that which opposes it, as fire lays hold of what falls into it, by which a small light would have been extinguished: but when the fire is strong, it soon appropriates to itself the matter which is heaped on it, and consumes it, and rises higher by means of this very material.
