text: Keep on as you have begun, and make all possible haste, so that you may have longer enjoyment of an improved mind, one that is at peace with itself. Doubtless you will derive enjoyment during the time when you are improving your mind and setting it at peace with itself; but quite different is the pleasure which comes from contemplation when one's mind is so cleansed from every stain that it shines. You remember, of course, what joy you felt when you laid aside the garments of boyhood and donned the man's toga, and were escorted to the forum; nevertheless, you may look for a still greater joy when you have laid aside the mind of boyhood and when wisdom has enrolled you among men. For it is not boyhood that still stays with us, but something worse, – boyishness. And this condition is all the more serious because we possess the authority of old age, together with the follies of boyhood, yea, even the follies of infancy. Boys fear trifles, children fear shadows, we fear both.
