Uncertainty of what will be turned up at Wikipedia adds to its lure. Contributions in some fields I've partially searched have been stronger than I had any reason to expect; philosophy is one of those fields.

In looking for statements related to epistemology and philosophy of science after this thread was started, I followed links and came to Wikipedia's List of basic philosopy topics.

I'd better read about all the -isms I haven't studied, to see whether I'm some -ist without knowing it.
