I think think one core aspect of wisdom, when you experience it in another human being, is that there is an integrity, a connection between inner life and outer presence in the world. Knowledge is something you can possess, intelligence is something you… can point at someone and say that’s an intelligent person. And wisdom is also — it’s a possession, but it’s a possession that is applied.
So the litmus test of wisdom is not just what is contained in that person, but their imprint on the world.
— Krista Tippett, in conversation with Pico Iyer
I think we know a wise person when we see them, but it’s often difficult to say exactly why we see them as wise. There’s an essential and critical difference between someone who is intelligent and someone who is wise—but how to describe the difference?
Krista Tippett captures it perfectly in the quotation above (and I strongly recommend you listen to her interview with Pico Iyer in full). The intelligent person is inward-directed. They may have a large inner life, but they draw no connection between their inner life and the outer world. Their knowledge exists within them, for themselves.
The wise person directs knowledge and intelligence toward the outer world, using it to shape and improve the world around them. They not only have the necessary knowledge, but understand how it should be used, leading what they know to be used valuably in their interactions with the world at large. And that makes all the difference.
