text: It seems to me erroneous to believe that those who have loyally dedicated themselves to philosophy are stubborn and rebellious, scorners of magistrates or kings or of those who control the administration of public affairs. For, on the contrary, no class of man is so popular with the philosopher as the ruler is; and rightly so, because rulers bestow upon no men a greater privilege than upon those who are allowed to enjoy peace and leisure. Hence, those who are greatly profited, as regards their purpose of right living, by the security of the State, must needs cherish as a father the author of this good; much more so, at any rate, than those restless persons who are always in the public eye, who owe much to the ruler, but also expect much from him, and are never so generously loaded with favours that their cravings, which grow by being supplied, are thoroughly satisfied. And yet he whose thoughts are of benefits to come has forgotten the benefits received; and there is no greater evil in covetousness than its ingratitude. Besides, no man in public life thinks of the many whom he has outstripped; he thinks rather of those by whom he is outstripped. And these men find it less pleasing to see many behind them than annoying to see anyone ahead of them. That is the trouble with every sort of ambition; it does not look back. Nor is it ambition alone that is fickle, but also every sort of craving, because it always begins where it ought to end.
