Abstract:Crazyism about X is the view that something that it would be crazy to believe must be among the core truths about X. In this essay, I argue that crazyism is true of the metaphysics of mind. A position is "crazy" in the intended sense if it is contrary to common sense and we are not epistemically compelled to believe it. Crazyism about the metaphysics of mind can thus be treated as the conjunction of two sub-theses: (1.) that something contrary to common sense must be among the core truths of the metaphysics of mind and (2.) that whatever that true thing is, we are not epistemically compelled to believe it. I defend the first thesis on grounds of the probable incoherence of folk metaphysics, from which follows that any fully fleshed-out metaphysics will inevitably conflict with some piece of that incoherent story. I defend the second thesis on three grounds: peer disagreement, lack of a compelling method for resolving metaphysical disputes about the mind, and the dubiousness of the general cosmological claims with which metaphysical claims about the mind are entangled.

The Crazyist Metaphysics of MindMysterians about the mind -Colin McGinn (1989McGinn ( , 2004 commonsensical metaphysics ought to be attractive to at least a certain portion of philosophers.At least it ought to command attention as a foil. It oughtn't be so downmarket as to be entirely invisible.1 For example, Frege 1884/1953, 1918/1956 (though see Reck 2005; Lewis 1986; Yablo 1987.
Schwitzgebel July 12, 2013Crazy Mind, p. 5Second possible explanation. Metaphysics is very difficult. A thoroughly commonsensical metaphysics is out there to be discovered; we simply haven't found it yet. If all goes well, someday someone will piece it all together, top to bottom, with no serious violence to common sense anywhere in the system. I fear this is wishful thinking against the evidence. In the next several sections I will discuss the case of the metaphysics of mind in particular.Third possible explanation. Common sense is incoherent in matters of metaphysics.Contradictions thus inevitably flow from it, and no coherent metaphysical system can respect it all. Although ordinary common sense serves us fairly well in practical maneuvers through the social and physical world, common sense has proven an unreliable guide in cosmology and probability theory and microphysics and neuroscience and macroeconomics and evolutionary biology and structural engineering and medicine and topology. If, as it seems to, metaphysics more closely resembles these latter endeavors than it resembles reaching practical judgments, we might excusably doubt the dependability of common sense as a guide to metaphysics.
2Undependability doesn't imply incoherence, of course. But it seems a natural next step in this case, and it would tidily explain the historical fact at hand.On the first explanation, we could easily enough invent a thoroughly commonsensical metaphysical system if we wanted one, but we don't want one. On the second explanation, ...
