Sec. VIII. As to the changes of the flatterer, which resemble those of the polypus,[376] a man may most easily detect them by himself pretending to change about frequently, and by censuring the kind of life he used formerly to praise, and anon approving of the words actions and modes of life that he used to be displeased with. He will then see that the flatterer is never consistent or himself, never loving hating rejoicing grieving at his own initiative, but like a mirror, merely reflecting the image of other people's emotions and manners and feelings. Such a one will say, if you censure one of your friends to him, "You are slow in finding the fellow out, he never pleased me from the first." But if on the other hand you change your language and praise him, he will swear by Zeus that he rejoices at it, and is himself under obligations to the man, and believes in him. And if you talk of the necessity of changing your mode of life, of retiring from public life to a life of privacy and ease, he says, "We ought long ago to have got rid of uproar[377] and envy." But if you think of returning again to public life, he chimes in, "Your sentiments do you honour: retirement from business is pleasant, but inglorious and mean." One ought to say at once to such a one, "'Stranger, quite different now you look to what you did before.'[378] I do not need a friend to change his opinions with me and to assent to me in everything, my shadow will do that better, but I need one that will speak the truth and help me with his judgement." This is one way of detecting the flatterer. Sec. IX. We must also observe another difference in the resemblance between the friend and flatterer. The true friend does not imitate you in everything, nor is he too keen to praise, but praises only what is excellent, for as Sophocles says, "He is not born to share in hate but love,"[379]
