Ouch, sorry to hear that! I'm fascinated to hear what happened but totally understand if you don't want to share.

For me, I've just become bored with the bluntness of rationalism. And in the dull sense rather than abrupt speech sense; though, ironically, perhaps its failure is related to the latter sense.
I've found rationalism is ineffectual in communicating with people I disagree with, so I'm looking for new tools. I think aphorisms, riddles, and an overall mysterious style helps people find the answer themselves. The problem with a lot of aphorism books -- though I've only read a handful -- is that they're so often trite. They lack wisdom; and, often, mystery.
