XXIX. (1.177) "For in thee shall all the nations of the earth be blessed." And this oracle applies to the wise man in respect of himself, and also in respect of Others.[the text is very corrupt here. I have followed Mangey's reading and translation.] For if the mind which is in me is purified by perfect virtue, and if the tribes of that earthly part which is about me are purified at the same time, which tribes have fallen to the lot of the external senses, and of the greatest channel of all, namely the body; and if any one, either in his house, or in his city, or in his country, or in his nation, becomes a lover of wisdom, it is inevitable that that house, and that city, and that country, and that nation, must attain to a better life. (1.178) For, as those spices which are set on fire fill all persons near them with their fragrance, so in the same manner do all those persons who are neighbours of and contiguous to the wise men catch some of the exhalations which reach to a distance from him, and so become improved in their characters.
