Will you not choose to see and to distinguish in respect to what men become philosophers, and what things belong to belong to them in other respects? And if I were a philosopher, ought you also to be made lame? What then? Do I take away these faculties which you possess? By no means; for neither do I take away the faculty of seeing. But if you ask me what is the good of man, I cannot mention to you anything else than that it is a certain disposition of the will with respect to appearances.
