The idealist does, of course, avoid an admission of epistemological dualism with respect to the knowledge of the physical world, in as much as he denies that there is - in the sense in which we have been using the term - any physical world to be known. For any belief in the possibility of true remembrance is not only a step out of subjectivism; it is also a step into epistemological dualism. The direct evidence for epistemological dualism from the nature of the memory-experience is, then, as plain for an idealist as for a realist, if the idealist admits that he had a past and is not wholly unacquainted with it. There is a familiar type of idealistic metaphysics in which these facts are recognized, so far as human knowing is concerned, but an attempt is made to escape their implications by invoking an Absolute Mind whose knowing is not subject to our infirmities.
