a pupil of Theophrastus, he wrote many admirable treatises during the time of that unfortunate leisure of his, not, indeed, for any utility to himself, for that was out of his reach, but the cultivation of his mind was to him a sort of sustenance for his human nature.
I, indeed, have often heard Cnæus Aufidius, a man of prætorian rank, of great learning, but blind, say that he was affected more by a regret for the loss of light, than of any actual benefit which he derived from his eyes. Lastly, if sleep did not bring us rest to our bodies, and a sort of medicine after labour, we should think it contrary to nature, for it deprives us of our senses, and takes away our power of action. Therefore, if either nature were in no need of rest, or if it could obtain it by any other means, we should be glad, since even now we are in the habit of doing without sleep, in a manner almost contrary to nature, when we want to do or to learn something.
XX. But there are tokens supplied by nature, still clearer, or, I may say, entirely evident and indubitable,—more especially, indeed, in man, but also in every animal,—that the mind is always desirous to be doing something, and can in no condition endure perpetual rest. It is easy to see this in the earliest age of children; for although I fear that I may appear prolix on this subject, still all the ancient philosophers, and especially those of our own country, have recourse to the cradle for illustrations, because they think that in childhood they can most easily detect the will of nature. We see, then, that even infants cannot rest; but, when they have advanced a little, then they are delighted with even laborious sports, so that they cannot be deterred from them even by beating: and that desire for action grows with their growth. Therefore, we should not like to have the slumber of Endymion given to us, not even if we expected to enjoy the most delicious dreams; and if it were, we should think it like death. Moreover, we see that even the most indolent men, men of a singular worthlessness, are still always in motion both in mind and body; and when they are not hindered by some unavoidable circumstance, that they demand a dice-box or some game of some kind, or conversation; and, as they have none of the liberal delights of learning, seek circles and assemblies. Even beasts, which we shut up for our own
