M. J. Young's Pages Chosen for Intellectual Challenge...
...is not yet here.
I apologize for any inconvenience. The new site is still being built, pages from all of the old sites being collected, links redirected, and everything being put in place so that it will all be here; but the indices have to be the last to move, so that they can point to the correct pages.
What is on this site can be accessed from its welcome page; the old pages (which unfortunately carry banners and other ads, depending on their server) are still in their original locations, and can be accessed there.
This page is still available here.
