The Logic Museum is a collection of source material, much of it Latin and medieval, on logic and metaphysical writing, and particular on the "big questions" like, does existence exist, for how long, and, is it open on Sundays sort of thing. Links below.

The latest set of pages (July 2006) is on connotation.
Some other of the big subjects:
Time and Eternity
Plus lots of other stuff, which you can access easily from the main page.
In June 2006 I will be working on a translation of the commentaries of Abelard, Boethius and Aquinas of the De Interpretatione.
