Jim is the author of Why Does the World Exist?, Stop Me If You’ve Heard This: A History and Philosophy of Jokes, and his latest, When Einstein Walked with Gödel. Andrew tees up the episode:I’ve known Jim forever, and he’s rather hard to introduce, but he’s one of the liveliest and rudest conversationalists I’ve ever known, so I thought he’d be a great podcast guest. It’s a bit of a break from the deadly seriousness of the past few weeks. Jim goes at me over “The Bell Curve,” performs a rant desanctifying Hitchens, and discusses quantum mechanics and its current travails. A bit philosophical at first, the whole chat was a trip.

I do not always agree with him, but by and large I find that he’s able to put into words what I can only feel abstractly. I especially enjoyed his conversation with Steven Pinker and his defense of rationality. Pinker is a wonderful thinker and responds to most of Andrew’s questions with not one, but three or four well-argued points. Quite amazing.However, I found that Andrew could have pushed Pinker harder on some points that I think he would not entirely agree with, especially the two moments when Pinker talked about the tension between “truth” (in a dry, empirical sense) and “tact,” which I found rather unconvincing. This is exactly where a purely “rational” worldview hits a wall. I’m reminded of a 2004 debate between philosopher Jürgen Habermas and future pope Joseph Ratzinger, in which they pretty much agreed that the liberal-democratic order is built upon a fundament of values that antedate it: the traditional Judeo-Christian values of love, compassion, solidarity, and the fundamental dignity of every person. These values, in my opinion, cannot be truly acquired by just being “rational.”Here’s Pinker on what he thinks is the most damaging delusion among Americans today — “the Myside Bias”:Another reader delves into natural law — and sodomy:I am Catholic-raised university student, currently struggling to understand the physiological, psychological, social, and religious aspects of outercourse (oral and anal sex). Some studies in the past two decades have found a correlation between oral sex and fewer complications during pregnancy and fewer miscarriages. The authors suggest immunological factors at play. The probability of an embryo implanting in the uterus is largely determined by immune-compatibility. Thus, by oral ingestion of paternal antigens in seminal fluid, gradual tolerance might be achieved in the mother. Similarly, since rectal absorption is also possible, anal sex might be relevant too in this regard.If this were indeed true, this might undermine the Church’s stance on sodomy — that it can’t be derived from the natural law and has no teleology. This would mean that these acts serve to prepare a woman’s body to successfully carry the child of their long-term partner. Now given the high rate of miscarriages (estimated to be 50% of pregnancies), this would reduce the large number of spontaneous abortions that arise naturally in traditional, procreative marriages.This fact would theologically not necessarily reconcile homosexuality and Catholic doctrine. However, it would shed new light on the issue of sexuality and the Church. It migh
