This website is hosted by WINHOST but they have reduced the memory allocation down to 100 Mb for the BASIC plan. Result is that this app runs too slowly and unreliably to be of use, even for this lightweight app. A lot of people consult this app so I will migrate the site to a better server within a few weeks.

This page features a web based syllogistic machine for exploring fallacies, figures, terms, and modes of syllogisms. Syllogistic logic was first developed by Aristotle and later refined by the Scholastics during the Middle Ages. Use of this syllogistic machine is self-explanatory. An exciting version of Stoic logic coming soon!
