ABSTRACT
Over and above global resemblance are to be distinguished certain partial similarities. These involve new discriminations, for while I may discern by very acute hearing that b is or is not the exact reproduction of a, I may not know whether they differ, for example, in intensity, quality, or duration, and resemble each other in pitch. By global resemblance alone, I should be able to identify only those notes that are given in the same way by the same instrument. Likewise, I should not be able to recognize a colour, form, or change in my visual field unless they were apprehended all together; and the same for the sense of touch. My sense-data would have only one way of resembling each other (by a direct and simple relation) and not several ways.
