 But Royce then argued that epistemological idealism ultimately entails a foundation of metaphysical idealism, in particular that “the question as to how we ‘transcend’ the ‘subjective’ in our knowledge”, that is, the purely individual, although it exists for both metaphysical realists and idealists, can only be answered by metaphysical idealists (1892: xiv). We will argue similarly that while epistemology can entail idealism, on the assumption that the isomorphism between knowledge and the known must be in some sense necessary and that this can be so only if the known as well as knowledge is in some sense mental, this should be distinguished from the more general and extremely widespread view that our knowledge is always formed within our own point of view, conceptual framework, or web of belief. This view may well be the default position of much twentieth-century philosophy, “continental” as well as “analytic”, but does not by itself entail that reality is essentially mental.
