For the hearer who is cognizant of the facts and partial to the dead will perhaps think that scant justice has been done in comparison with his own wishes and his own knowledge, while he who is not so informed, whenever he hears of an exploit which goes beyond his own capacity, will be led by envy to think there is some exaggeration. And indeed eulogies of other men are tolerable only in so far as each hearer thinks that he too has the ability to perform any of the exploits of which he hears;
