YES, philosophy is a joke!! When you make up a joke about things philosophical, and then tell it, it IS a joke. D. needs a sense of humor---first and foremost.

Simple as that.

And the great old joke: Descarte goes into0 a bar. Bartender asks him, "Would you like a beer?" He answers, "NO"---and disappears.

ANYTHING is fodder for jokes. Like philosophy, humor can shed it's own sort of light on any topic at all.
