Wise, like all words have several variations of meaning, but it has always meant to me, more or less:
“having the power of discerning and judging properly as to what is true or right; possessing discernment, judgment, or discretion.” (see dictionary.com)
I have found that it also depends on who’s opinion of wisdom you’re seeking.
In looking at wise as a visual, I’ve found wisdom, across cultures, genders and ages. So in my travels, in a supermarket, a daycare center, a senior center, across the road, the city, the country, and around the world, I see wise faces in the hope of a woman, the essence of a child, and the wrinkles of an old man. I’ve found the key is being able to see wisdom, at all.
Look for wisdom, in all ages and in all people, we all have some to give. Peace to you all.
