or pounds hellebore and compels him to drink it,—neither in the one case making unpleasantness, nor in the other pleasantness, his end and aim, but in both studying only the interest of his patient,—so the friend sometimes by praise and kindness, extolling him and gladdening his heart, leads him to what is noble, as Agamemnon,
or Diomede,
But where on the other hand there is need of correction, then he rebukes with biting words and with the freedom worthy of a friend,
Sometimes also he joins action to word, as Menedemus sobered the profligate and disorderly son of his friend Asclepiades, by shutting him out of his house, and not speaking to him. And Arcesilaus forbade Bato his school, when he wrote a line in one of his plays against Cleanthes, and only got reconciled with him after he repented and made his peace with Cleanthes. For we ought to give our friend pain if it will benefit him, but not to the extent of breaking off our friendship; but just as we make use of some biting medicine, that will save and preserve the life of the patient. And so the friend, like a musician, in bringing about an improvement to what is good and expedient, sometimes slackens the chords, sometimes tightens them, and is often pleasant, but always useful. But the flatterer, always harping on one note, and accustomed to play his accompaniment only with a view to please and to ingratiate himself, knows not how either to oppose in deed, or give pain in word, but complies only with every wish, ever chiming in with and echoing the sentiments of his patron.
