For though Nature seeks by all means to delight and rejoice herself, yet the bodies of old men are incapacitated for all pleasures, except a few that are absolutely necessary. For not only Venus to old men is averse, as Euripides has it; but their appetite also to their meat and drink is for the most part dull, and as one would say, toothless; so that they have but little gust and relish in them.. They ought therefore to furnish themselves with pleasures of the mind, not ungenerous or illiberal, like those of Simonides, who said to those who reproached him with covetousness, that being by his years deprived of other pleasures, he recreated his old age with the only delight which remained, that of heaping up riches. But political life has in it pleasures exceeding great, and no less honorable, being such as it is probable the very Gods do only or at least chiefly enjoy themselves in; and these are the delights which proceed from doing good and performing what is honest and laudable. For if Nicias the painter took such pleasure in the work of his hands, that he often was fain to ask his servants whether he had washed or dined; and if Archimedes was so intent upon the table in which he drew his geometrical figures, that his attendants were obliged by force to pluck him from it and strip him of his clothes that they might anoint him, whilst he in the mean time drew new schemes on his anointed body; and if Canus the piper, whom you also know, was wont to say that men knew not how much more he delighted himself with his playing than he did others, for that then his hearers would rather demand of him than give him a reward; do we not thence conceive how great pleasures the virtues afford to those who practise them, from their honest actions and public-spirited works tending to the benefit of human society? They do not tickle or weaken, as do such sweet and gentle motions as are made on the flesh; for these indeed have a furious and unconstant itching, mixed with a feverish inflammation; whereas those which accompany such gallant actions as he who rightly administers the state is worker of, not like the golden plumes of Euripides, but like those celestial wings of Plato, elevate the soul which has received a greatness of courage and wisdom accompanied with joy.
