 Theories of aesthetic experience may be divided into two kinds according to the kind of feature appealed to in explanation of what makes experience aesthetic: internalist theories appeal to features internal to experience, typically to phenomenological features, whereas externalist theories appeal to features external to the experience, typically to features of the object experienced. (The distinction between internalist and externalist theories of aesthetic experience is similar, though not identical, to the distinction between phenomenal and epistemic conceptions of aesthetic experience drawn by Gary Iseminger (Iseminger 2003, 100, and Iseminger 2004, 27, 36)). Though internalist theories—particularly John Dewey’s (1934) and Monroe Beardsley’s (1958)—predominated during the early and middle parts of the 20th century, externalist theories—including Beardsley’s (1982) and George Dickie’s (1988)—have been in the ascendance since. Beardsley’s views on aesthetic experience make a strong claim on our attention, given that Beardsley might be said to have authored the culminating internalist theory as well as the founding externalist one. Dickie’s criticisms of Beardsley’s internalism make an equally strong claim, since they moved Beardsley—and with him most everyone else—from internalism toward externalism.
