 Rationality is claimed by Davidson to be constitutive of the mental in the sense that something only counts as being a mind—and thus an appropriate object of psychological attributions—if it meets up to certain rational standards. This constitutive idea is open to weaker and stronger interpretations. The weaker interpretation sees only very basic logical, semantic or conceptual constraints on understanding others—and thus what is constitutive of minds—which allows for significant variation as one moves further out from these to more substantive principles of practical reasoning and theoretical reasoning, and even more when extending out further to desires and values. The stronger interpretation appears to be suggested in the quote from Davidson immediately above. In requiring consistency, true beliefs and appropriate desires, it appears to require maximizing agreement between interpreter and interpreted, and thus a maximal conception of what is constitutive of minds. The weaker interpretation instead requires merely minimizing inexplicable error on the part of the creature being interpreted, thus allowing for significant deviations from psychological assignments that might be required by the stronger interpretation. On this view, the interpreter puts himself into the shoes of the interpreted, acknowledging evidential and cognitive limitations that might prevent her from achieving maximal rationality (Grandy 1973). As we will see in this section, how one interprets the notion of rationality as constitutive directly affects how the argument for mental anomalism is interpreted to work.
