I am a newly retired professor emeritus from the University of Pittsburgh where I taught Rhetorical, Critical, Political, Western Marxist, and Cultural theories for 26 years. Since I now have time to devote myself to other intellectual matters as well, I have become reinterested in Mathematics, especially Set Theory, Analysis, and Topology, which I studied briefly in the mid 1970s under Robert Fefferman as an undergraduate Math major in the College of the University of Chicago. ©
