A quote
Furthermore, that which you mention is the mark of an already perfect man, of one who has attained the height of human happiness. But the approach to these qualities is slow, and in the meantime in practical matters, the path should be pointed out for the benefit of one who is still short of perfection, but is making progress. Wisdom by her own agency may perhaps show herself this path without the help of admonition; for she has brought the soul to a stage where it can be impelled only in the right direction. Weaker characters, however, need someone to precede them, to say: “Avoid this,” or “Do that.”
