@The Pentacle Queen,
When I first saw the thread title, I thought I read the humor of philosphy
then I thought isn't that an oxymoron. Then I reread the title... and oh that makes sense.
But the science of jokes and humor is really counterproductive or at least how several authors on the subject I have heard talk about their research seem to imply. Once you start dissecting a joke, its components, its context, its target, etc... then the joke stops being funny.
Absurdity reminds us of the abyss over which concepts float, humour seems to act in the same way. In a lot of ways I think humour is probably the most profound reaction to life.
That's why we can still joke about other people
dying. It's a reflex from our own insecurities on the finite nature of life.
Only with a leveral of maturity can we as individuals joke about our own up and coming deaths.
