Hello!
I would also like to add my two cents on the issue and raise another question about the difference of wisdom and intelligence.
A conflicting situation in which a person has to decide, I believe the one who prefers wisdom (the one the author of the essay describes - the attribute coming mainly from humility and discipline) will first tend to look at the big picture and weigh all the possibilities to reach a conclusion best for everyone.
Meanwhile, a person that is more intelligent than wise (a.k.a. has good peaks of performance rather than good performance in general) will first think of him/herself and attempt to capitalize on his/her knowledge of the grander scheme of things rather than seeking to create a more beneficial outcome for all involved.
In short, I believe wisdom itself is a virtue while intelligence is not and intelligence itself is basically what wisdom is save the humility, empathy and intuition.
Intelligence is calculative, discontent about everything and it makes you scheme and invent constantly while wisdom is deep-rooted. It does come from experience but only the kind that you not only go through, but the one you accept, grow over and learn your lesson from.
Intelligence itself is a trait that can make you in fact super unhappy - just look at all of us - the hyper-intelligent milennials who truly are very smart, clever and fast, but how many of us are in any way happy, satisfied or inspirational?
Intelligence breeds deppression while wisdom soothes it and gives borne to serenity - our better selves.
Anyway, the essay is very alluring and it raises some important points while exhaustively covering all the possible and impossible probabilities and angles to view the issue from.
Overall I agree with your reply, @hr1, but I don't think you're focusing on the correct aspects of these two attributes and that the essence of their intricate dissimilitude lies more within their exact nature than in the abilities that their presence provides and applies.
To me, intelligence is reason. Emotionless, calculative head.
Whereas wisdom is that plus the heart's guidance - conscience of one's self in connection with empathy (the knowledge and respect for the existence of more than just one's self).
A very refreshing topic to be raised. Thanks for making me think about this!
