Exhort the young to virtue not only by your precepts but by exemplifying in your conduct what good men ought to be. Teach your children to be obedient, and habituate them to devote themselves above all to the discipline which I have described; for if they learn to submit to authority they will be able to exercise authority over many; and if they are faithful and just they will be given a share in my privileges; but if they turn out to be bad they will be in danger of losing all the privileges which they possess.
