Ive never thought of joining the AAUP; this vindicates my indifference. Whether or not theres a military recruiter on campus has nothing to do with academic freedom, which I thought had to do with the freedom of teaching and inquiry (within the limits of the law of libel, say). Im still in control of my syllabus. My research and writing agendas are unaffected. The university remains a big tent, in aspiration, if not necessarily always in fact.
