I recommend the playing of games with one's contemporaries, but only those that contribute to education and building of one's body: educational games and playing with numbers, such as those for learning arithmetic, or physical games of attack and defence, or of attack and ambush in chess. Such games teach one not to overlook anything. All such things, however, should be done in moderation. There are those who abandon their duties to devote themselves to play. I say that games should be played in spare time and alongside one's studies. Playing with dice and cards I reject.
