Sure, Whatever, Let's Try Another Contra Caplan On Mental Illness

Latest rebuttal to Bryan Caplan's claim that 'no preference is a disease' (mental illnesses are just stigmatised voluntary preferences, vs physical illnesses which are constraints). Scott offers four counterarguments: (1) the preference/constraint model fails for PHYSICAL illness too -- under behaviourism a migraine is 'a preference for sitting in a dark room saying ow', a cold 'a preference for staying in bed', so drop behaviourism and admit internal states; (2) gradients -- the demon-makes-you-run example, the dimmer-switch on leg nerves, holding your breath: preferences shade continuously into constraints with no qualitative line; (3) physical illnesses contain preferences (cancer fatigue) and mental illnesses contain constraints (psychotic disorganisation, panic tachycardia, insomnia); (4) the gun-to-the-head test fails (depressive suicide, suicide-by-cop) or else is unfalsifiable. Underlying thesis: 'is X a disease' is a category-boundary question mixing facts and values, usually easy (cancer) sometimes hard (homosexuality) -- and Caplan's disease-or-homosexuality fork is two different incoherent ideas you can reject independently (the Prader-Willi extreme-hunger and Down-syndrome examples).

Quality 74 · Strong. Strong, upper end. Sharp, generative philosophy-of-psychiatry -- the physical-illness parallel and the gradient thought-experiments genuinely dissolve the preference/constraint dichotomy, and the facts-plus-values account of disease is clarifying. Held just below Excellent as the Nth round of a long-running debate, reapplying his established framework.

Claude’s paradigm shift 52 · Moderate. Moderate. The disease-as-facts-plus-values view and the constraint critique are Scott's recurring positions; the fresh element is the specific battery of counterexamples, not a new idea.

Real-world impact 2 · Minor. Minor. Lives in the philosophy-of-psychiatry / Szasz-Caplan discourse; no institutional or material reach. Within-niche.
