 The multiple ‘ways’ in which the same property can be represented, according to Peacocke, are not modes of presentation of the sort that constitute the contents of beliefs. In the three putative examples of single properties that are represented in different ways (the four-sided figure, the middle C/F-sharp interval, and the arrangement of dots), there are (according to Peacocke) multiple concepts in the vicinity that pick out the same shape, interval, or arrangement. The concepts ‘regular diamond’ and ‘regular square’, or simply two occurrences of ‘that shape’, one for each way of seeing the four-sided figure; the concepts ‘augmented fourth’ and ‘diminished fifth’ in the case of the interval; and the concepts ‘row’ and ‘column’ in the case of the dots. These concepts differ from the perceptual ‘ways’ of representing the shape (or the interval or the dot-arrangement), according to Peacocke, in that the perceptual ‘ways’ make it possible to acquire the concepts, and so cannot be identical with them. In the case of the two demonstrative shape concepts, these are anchored to each shape by the experience of it, and in order to play this role, they cannot be the same as demonstrative concepts (a point echoed by Heck). In his (1992), Peacocke uses the label ‘proto-propositional content’ for contents just described. The discussion of these examples in his (2001) is intended to clarify the 1992 discussion (see 2001, fn 14).
