  It is unlikely, however, that these two forms of justification internalism will stand up to close scrutiny. To see this, consider a case of rapid acquisition of many justified beliefs at a single moment or in a very short and hurried period of time. We need only think of some emergency situation where very swift reactions are needed, and where the presence of the emergency is based upon a host of sensory cues. In such cases a person will often acquire a battery of justified beliefs, all pretty much in an instant of time, and quick action on those beliefs is necessary to avert some disaster or other unwanted consequence. Certainly the person cannot access, at the acquisition moment, all of the justifiers for each of these newly acquired justified beliefs; she is too busy taking steps to avert the disaster. Nor should we think that she will be able to access all of the justifiers for those beliefs at a later, and calmer time; for, however good her memory might be, it is just unrealistic to suppose that each person will be able to recall all of those justifiers for every one of those justified beliefs. This would be too great a demand to place on memory in the interests of an epistemological theory. It is better to give up the epistemological theory in favor of something more feasible.  Such a view is easy enough to come by; we simply weaken things to yield partial justifier accounts of justification internalism.
