I like going through old dictionaries sometimes. The internet
   archive has scans of dictionaries going back to the 1600s, and
   I'll compare definitions from today and back then. I also love
   etymology: for example: What is "think"? Think is related
   directly to the word thing. What's a thing? It's an assembly of
   people meeting in secret and debating/discussion issues until
   they come out with a singular result. A thing. An assembly.
   Think. An assembly. But an assembly of what? [comes from German]
   == So, fascinating stuff. Concepts don't seem to have
   ontological status. We make them that way. They're constructed
   "things". Even "concept" - comes from 17th century medicine.
   They saw the formations of the brain and decided that the head
   was a womb, the brain was like a baby, and thoughts are
   "conceived". That way of thinking (thinging, assembing together)
   has carried forward to today. ==
