Yes, I did read it. I’m going to need a source that says that was written by Diogenes Laertius quoting sometime else, not a quote of him, and he was quoting Diogenes of Sinope and not one of the other “pretty much all of the famous Greek philosophers”.
Maybe you should brush up on basic logic with Aristotle.
That’s better. I guess the Aristotle helped with making coherent arguments.
