Think you to be a philosopher while acting as you do? think you to go on thus eating, thus drinking, giving way in like manner to [your own] wrath and to displeasure? Nay you must watch, you must labor; overcome certain desires; quit your familiar friends, submit to be despised by your slave, to be held in derision by them that meet you, to take the lower place in all things, in office, in positions of authority, in courts of law. Weight these things fully, and then, if you will, lay to your hand; if as the price of these things you would gain Freedom, Tranquility, and passionless Serenity. (104)
