More in the Logic Museum

1. A new page on the Ars Vetus, or 'old logic' of the scholastics. This includes three of the seven works of the old logic, with the Latin translations of Aristotle's Greek in parallel with English.

2. Some pictures of the 2007 Montreux conference on the square of opposition, retrieved from my original site.

Every man is an animal

But is 'Every man is an animal' true when there are no men? Some new pages in the Logic Museum on the medieval dispute about this question. The main page outlines the controversy (which lasted from the early thirteenth to the late sixteenth century). The first subpage contains new translations (and Latin sources fresh to the web) of early writings on the subject. Much more to follow.

A splendid new page in the Logic Museum here.

The Square of Opposition

Just to draw attention to the page in the Logic Museum on the famous square. Plenty of material there, and plenty coming up, particularly of relevane to my dispute with Terence Parsons about the semantics of the O proposition.
