 More than any other area, the metaphysics of memory reflects the trend towards interdisciplinarity noted above, and work in this area sometimes shades into philosophy of psychology (Rowlands 2009) and philosophy of neuroscience (Bickle 2011). Relevant work in the philosophy of psychology is discussed here as appropriate; for more specialized work in the philosophy of neuroscience, see the entry on that topic. The central aim of mainstream research on the metaphysics of memory is to develop a theory of remembering: a general but informative account of what it is for someone to remember something. As we will see, however, there are multiple kinds of memory. It is unclear whether it is feasible to develop a theory of remembering that applies to all of these, and ultimately it may prove necessary to develop multiple theories of remembering, corresponding to the multiple kinds of memory. (Something similar may go for the epistemology of memory [Teroni 2014].)
