"In all his works and articles, there is not a single philosophical proposition." The book is contested, however, and Lévy sought legal action against the authors."

Isn't Levy the one who thought he was a superman or something? So, that's an idea, isn't it?

Personally, I seriously doubt that philosophy can be fruitfully taught. I think it can be believed in as any religion can be, but not taught.
Levy learned philosophy- and that concisely explains all you need to know about Levy.

Now, I'm not saying there is no value to it. It might help you develop a certain sense of humor, instill a sense of humility, and in general, learn what not to do. And in that sense, it might be the best that any general education can offer.
