[1] Plato ¹ says, my dear Antiochus Philopappus, that everyone grants forgiveness to the man who avows that he dearly loves himself, but he also says that along with many other faults which are engendered thereby the most serious is that which makes it impossible for such a man to be an honest and unbiased judge of himself. For Love is blind as regards the beloved, ² unless one, through study, has acquired the habit of respecting and pursuing what is honourable rather than what is inbred and familiar. This fact affords to the flatterer a very wide field within the realm of friendship, ³ since in our love of self he has an excellent base of operations against us. It is because of this self-love that everybody is himself his own foremost and greatest flatterer, and hence finds no difficulty in admitting the outsider to witness with him and to confirm his own conceits and desires. For the man who is spoken of with opprobrium as a lover of flatterers is in high degree a lover of self, and, because of his kindly feeling toward himself, he desires and conceives himself to be endowed with all manner of good qualities; but although the desire for these is not unnatural, yet the conceit that one possesses them is dangerous and must be carefully avoided. Now if Truth is a thing divine, and, as Plato ⁴ puts it, the origin of all good for gods and all good for men, then the flatterer is in all likelihood an enemy to the gods and particularly to the Pythian god. For the flatterer always takes a position over against the maxim Know thyself, by creating in every man deception towards himself and ignorance both of himself and of the good and evil that concerns himself; the good he renders defective and incomplete, and the evil wholly impossible to amend.
