Actually...  excellent point.  That old article really was awful, with lots of peacock terms and didn't actually say much.  That said, "Will" is used differently in philosophy (some think of it as some active, tangible force rather than simply inclinations, like in idealism); a general definition would probably only say "Will is" (as noted by someone on this talk page), so I tried to make it into a long-form disambiguation page.  Most people will click on Free Will and be done with it.  Do you think that this satisfies the problem?
