Not everyone is lucky enough to journey into the "country for old men" (and women). And even among those who are lucky enough to reach old-age, not all learn as much from the journey as they might. Some arrive at the destination having missed the journey.
Growing old is inevitable, growing up is optional.
Is practical wisdom valuable?
Even in a society which is increasingly technical and technological, there is some sense that wisdom is a worthy goal, a knowledge worth attaining. Adapting the words of Aristotle in Nichomacean Ethics only a little, we can see that his observation applies still today:
"Although the young may be experts in geometry and mathematics [and technology and computers] and similar sorts of knowledge, they nonetheless lack practical wisdom. Such wisdom is gained from experience which the young do not possess, for experience is the fruit of years." (adapted from Nichomachean Ethics 1142a).
So even while we may rely on our children, our grand-children or both to help us download apps to our mobile phone, to show us how to connect our "smart" television to Netflix and how to stream music through Spotify to our tablet and other devices, there is still a place for wisdom.
