text: Bodily goods are, to be sure, good for the body; but they are not absolutely good. There will indeed be some value in them; but they will possess no genuine merit, for they will differ greatly; some will be less, others greater. And we are constrained to acknowledge that there are great differences among the very followers of wisdom. One man has already made so much progress that he dares to raise his eyes and look Fortune in the face, but not persistently, for his eyes soon drop, dazzled by her overwhelming splendour; another has made so much progress that he is able to match glances with her, – that is, unless he has already reached the summit and is full of confidence. That which is short of perfection must necessarily be unsteady, at one time progressing, at another slipping or growing faint; and it will surely slip back unless it keeps struggling ahead; for if a man slackens at all in zeal and faithful application, he must retrograde. No one can resume his progress at the point where he left off. Therefore let us press on and persevere. There remains much more of the road than we have put behind us; but the greater part of progress is the desire to progress.
