 Though the distinction between kinds of evidence isn’t well drawn by Beardsley, that may be because when he wrote “The Intentional Fallacy” his views weren’t as clear or definite as they were later to become, or because he later changed his mind and became more tough-minded. Intermediate evidence is never mentioned in Aesthetics or in any of his subsequent writings, and if the distinction between internal and external evidence is considered only as it’s drawn in Aesthetics, it’s relatively clean: internal evidence is evidence based on a direct inspection of the aesthetic object and nothing else; external evidence is evidence based on sources outside the object. That at least seems to draw a fairly bright line between the internal and the external. Unfortunately, drawing the distinction this way re-introduces the problems about not using external sources noted above in relation to the intentional fallacy.
