Arguing about Psychiatry: Natural Selection, Austinian Conservatism, and Finding Our Way to the Best

P rofessors Murphy and Lieberman have offered two generous and interesting commentaries on my article, each very insightful and helpful in its own way, and each offering an interesting alternative characterization of the subject matter of psychiatry. I found each extremely thought-provoking, hence this rather bloated response. I strongly disagree with each. In brief, I disagree with the ‘preliminaries’ of each commentary, struggle to see the tension between Hull’s view of science and my view of psychiatry, reject Lieberman’s appeal to the history of mind-like and mental-illness-like concepts, and finally, believe my position neither suffers from the instability of psychiatry, nor blocks the route to best practice, nor counsels despair.
