Reading some student blogs, I was reminded of a passage from Aquinas that I discovered in college. Aquinas asks whether hope abounds in young men and drunkards. He answers in the affirmative:
Youth is a cause of hope for three reasons, as the Philosopher states in Rhet. ii, 12: and these three reasons may be gathered from the three conditions of the good which is the object of hope--namely, that it is future, arduous and possible, as stated above.
For youth has much of the future before it, and little of the past: and therefore since memory is of the past, and hope of the future, it has little to remember and lives very much in hope.
Again, youths, on account of the heat of their nature, are full of spirit; so that their heart expands: and it is owing to the heart being expanded that one tends to that which is arduous; wherefore youths are spirited and hopeful.
Likewise they who have not suffered defeat, nor had experience of obstacles to their efforts, are prone to count a thing possible to them. Wherefore youths, through inexperience of obstacles and of their own shortcomings, easily count a thing possible; and consequently are of good hope.
Two of these causes are also in those who are in drink--viz. heat and high spirits, on account of wine, and heedlessness of dangers and shortcomings. For the same reason all foolish and thoughtless persons attempt everything and are full of hope.
I think that this also explains why the young don't appreciate the Aeneid.
