Note 118 — X

The foregoing discussion is in many ways similar to Brentano's upon the same subject. In discussing his first class of modes of consciousness, the Vorstellungen, he says: "We find no contrasts between presentations excepting those of the objects to which the presentations refer. Only in so far as warm and cold, light and dark, a high note and a low, form contrasts can we speak of the corresponding presentations as contrasted; and, in general, there is in any other sense than this no contrast within the entire range of these conscious processes" (Psychologie vom empirischen Standpunkte, Bd. I, p. 29). This may stand as against any attempt to find contrast between abstract sense-qualities taken apart from their objective reference. What is, however, the ground of distinction between the presented objects? Apparently this must be answered in the last resort as above. In this sense we should need finally to interpret "sensuous" and "material" in terms of objectivity as above defined, rather than the reverse. They are cases in or specifications of the determination of adequate stimuli.
