You yourself will judge whether I have added anything in the way of learning to the young men whom you have sent.  I hope that this addition, however little it be, will get the credit of being great, for the sake of your friendship towards me.  But inasmuch as you give less praise to learning than to temperance and to a refusal to abandon our souls to dishonourable pleasures, they have devoted their main attention to this, and have lived, as indeed they ought, with due recollection of the friend who sent them hither.
