The wise man's eyes are in his head; but the fool walks in darkness: and I myself perceived also that one fate happens to them all.
All Commentaries on Ecclesiastes 2:14 Go To Ecclesiastes 2
Ambrose of Milan
Let us make note of the fact that the body of a person is constructed like the world itself. As the sky is preeminent over air, earth and sea, which serve as members of the world, so we observe that the head has a position above the other members of our body. In the same way, the sky stands supreme among the other elements, just as a citadel amid the other outposts in a city’s defense. In this citadel dwells what might be called regal Wisdom, as stated in the words of the prophet: “The eyes of a wise man are in his head.” That is to say, this position is better protected than the others and from it strength and prevision are brought to bear on all the rest. .
