If you type the term "wisdom" into Google, you'll get about 3.1 million results. "Stupidity," on the other hand, yields 5.1 million hits. Now, stupidity isn't exactly the 100% opposite of wisdom. But let's try foolishness and end up with about 140,000 hits.
Apparently, it's difficult to depict the concept of wisdom in images. Well, images do appear, but these in turn depict words, poems, and characters. When I created a Zen garden 15 years ago, I had to decide which stones and their meanings I wanted to place there. One important stone became the "stone of wisdom." Since then, I've read much about wisdom, invented it myself, and discussed it with others. And I have to admit, "I'm as smart as I was back then."
