This man, therefore, is happy in no less a degree than the one whom I mentioned before, inasmuch as he is free from all depression or melancholy, and as he enjoys a life exempt from sorrow and exempt from fear, having no connection, not even in a dream, with any painful or austere plans of life, because every part of his soul is wholly occupied by joy. And next to the man who has acquired self-taught virtue, and who has availed himself of the riches of nature, the third person who is made perfect is the meditator on and practiser of virtue, who receives as his especial reward the sight of God; for as he has had experience of all the things which can occur in human life, and as he has attained to a most intimate understanding of them, and has shrunk from no labour and from no danger which might enable him to track out and overtake that most desirable thing, truth, he has found in connection with human life and with the human race a great deal of darkness both by land and sea, and in the air, and in the atmosphere. For the atmosphere and the whole of heaven has presented to him the appearance of night, since every nature which is discernible by the outward senses is indefinite; and what is indefinite is akin to and closely resembling darkness.
