I really don’t know. For some time, I’ve been avoiding looking closely at the origins of logic, and specifically modal logic, in the writings of Aristotle. I’ve run out of excuses and I finally downloaded a copy of Aristotle’s “Categories” (E.M. Edgehill’s translation, from the Gutenberg project), to start looking it over. I will have a little more to say on this when I’ve studied more of it.
One of my ongoing projects has to do with writing what I call historical fantasy. I finally broke down and connected two areas of particular changes and movements; namely stone age developments and the agricultural revolution, all the way back to their origins in the Knoweldge Base. This should allow me to do more with those subjects.
