The Concent of Saunt Leibniz.

We can try turning old monasteries into concents à la Neal Stephenson's Anathem. People can go for a year in a unarian math to just study. Maybe a four consecutive years in such a math get equivalent recognition to a university degree. Whether it is the traditional monastic discipline or the Cartasian discipline, the required basic infrastructure is probably similar. Jeejahs stay outside, of course.

Particularly determined professors can populate a decennarian, maybe even a centenarian. Also, isn't there only about 9 years before our scheduled visit by the Icosahedron?
