 The token-identity thesis has been the subject of a number of interesting criticisms. Many of them, however, are difficult to bring fully into contact with Davidson’s own particular version of the thesis, primarily because Davidson’s version is derived a priori from the other premises in his framework. So, for instance, it has been argued that mental events do not bear the burden of the spatiotemporal precision of physical events that they would need to if the former were genuinely identical to the latter (Hornsby 1981; Leder 1985). For example, it would seem arbitrary to identify the deduction of some conclusion from a chain of reasoning with some particular neural event or set of neural events occurring at a specific time and place in the brain—especially given the micro-precision of the neural framework. Compare attempting to provide physical description for the action of paying back a debt—how does one determine the spatial and temporal parameters with the precision demanded by the language of physics? Distinguishing between “the” physical event, as opposed to its causes and its effects, can seem daunting if not outright nonsensical (Leder 1985; see also di Pinedo 2006). Further, it has been argued that the only possible empirical evidence for specific token-identity claims could be type-identities between either those or other mental and physical properties, because evidence needs to be drawn from variant cases in order to sort out merely coincident from identical events (Leder 1985).
