Although reliabilism might seem to be particularly suited to accounting for the diachronic aspects of the justification of memory belief, other theories we've looked at are able to accommodate the historical point too.  Exactly how these diachronic components figure into a full-blown theory of the justification of memory belief is a complex and controversial matter.  This is not the place to arbitrate between competing epistemic perspectives.  Suffice it to say that the kinds of general problems we've seen in standard theories of justified memory belief can apparently be handled within the theoretical means available to foundationalist and coherentist epistemologies.  Each theory can be amended, for instance, to simply require that when the memory belief has not come to be based on new information it will be now justified only if it was justified when the belief was initially formed, where the conditions of initial justifications are those that theory spells out.
