Cooperation with sins against prudence and chastity

Here’s another unpublished talk which I’ve posted at my main website.  It’s titled “Cooperation with Sins against Prudence and Chastity,” and I presented it at the Dominican House of Studies in Washington, D.C. in March of 2018, and at Blackfriars Hall at the University of Oxford in January of 2019.  The lecture discusses Aquinas’s account of the nature of prudence or practical wisdom, and of sexual immorality as more corrosive of prudence than any other sin.  It then applies this account to a critique of the pastoral advice given by some churchmen in the wake of Pope Francis’s Amoris Laetitia.  That advice, I argue, amounts to cooperation with sins against chastity, and against prudence more generally.  You can listen to an audio version of the lecture here.
