This is worth reproducing; I came to essentially the same conclusion (emphasis added):
The viciousness with which this book [Mind and Cosmos] was received is, quite frankly, astonishing. I can understand why scientists don't like it; they're wary of philosophers trespassing on their terrain. But philosophers? What is philosophy except (1) the careful analysis of alternatives (i.e., logical possibilities), (2) the questioning of dogma, and (3) the patient distinguishing between what is known and what is not known (or known not to be) in a given area of human inquiry? Nagel's book is smack dab in the Socratic tradition. Socrates himself would admire it. That Nagel, a distinguished philosopher who has made important contributions to many branches of the discipline, is vilified by his fellow philosophers (I use the term loosely for what are little more than academic thugs) shows how thoroughly politicized philosophy has become. I find it difficult to read any philosophy after, say, 1980, when political correctness, scientism, and dogmatic atheism took hold in academia. Philosophy has become a handmaiden to political progressivism, science, and atheism. Nagel's "mistake" is to think that philosophy is an autonomous discipline. I fully expect that, 100 years from now, philosophers will look back on this era as the era of hacks, charlatans, and thugs. Philosophy is too important to be given over to such creeps.
One such creepy thug is this corpulent apparatchik of political correctness:
