Doing some light reading in Philo (Wikiedia link) for my thesis, I came across this passage:
And its name shows its power; for the nation is further called, in the language of the Hebrews, Israel, which name being interpreted means, "seeing God." But of sight, that which is exercised by means of the eyes is the most excellent of all the outward senses, since by that alone all the most beautiful of existing things are comprehended, the sun and the moon, and the whole heaven, and the whole world; but the sight of the soul which is exercised, through the medium of its dominant part excels all the other powers of the soul, as much as the powers of the soul excel all other powers; and this is prudence, which is the sight of the mind. (De Abrahamo 56-57)
Sight is important, but is it really as superior as Philo believes? Keep in mind, he is also speaking of "seeing" in an abstract sense.
