Barry Schwartz and Kenneth Sharpe's Practical Wisdom is an excellent book. I find their argument that practical wisdom is superior to both rules and incentives as a way to organize social practices is compelling. They are right that Aristotle's case for practical wisdom is something that is in the grasp of all and very helpful to happiness. In this Schwartz and Sharpe align their argument with the positive psychology of Martin Seligman, with whom they say they have often talked, about what makes for authentic happiness.
But Aristotle goes on at the end of the Nicomachean Ethics to say that the greatest happiness does not come from practical wisdom or the exercise of the moral virtues - the subject of the first 9/10ths of the book. Instead, he concludes that the greatest happiness comes from contemplation. This has posed a puzzle for those trying to follow Aristotle for millennia, as he seems to negate in his conclusion the whole argument he had been building.
Aristotle says that contemplation is what the gods do. When we contemplate, we participate, as we are able, in the divine.
I think there is great wisdom in the idea that our highest happiness comes from participating in the divine. And this wisdom is something that even very smart secular approaches to happiness, and to wisdom, will miss.
