You may be unfamiliar with the concept of "Professor Emeritus", Peter. Contrary to what you appear to believe, it means nothing more than forgoing salary (which in my case I can easily afford thanks to my participation in the very early days of engineering workstations) and the right to vote on Academic Council (which I'd never exercised at any time). I still have an office, can teach courses, advise students, serve on committees (I was on the Ph.D. admissions committee the previous two years), and so on.
If you look at <a href="http://boole.stanford.edu/pratt.html" rel="nofollow">my home page</a> you'll see that I maintain an active research program in a number of areas of academic interest.
Unlike you I don't normally depend on <I>ad hominem</I> arguments to make my case, since science has stronger arguments. But since that seems to be your style I'll make an exception in your case by comparing you to David Springer.
You're no better. Both of you would be more convincing if you'd stick to substantive arguments and not depend so heavily on crude <I>ad hominem</I> attacks like the ones you bring to bear on everyone who disagrees with you.
