 Goodman’s insight about grid patterns and pictures suggests an immediate difficulty for explaining the digital status of images displayed on LCD screens: Clearly it will not be sufficient to point out that such images are pixellated, and therefore made up of small identical building blocks that impose a lower limit on the differences between display-instances. Remember that pictures are defined by color, shape, and size, which vary continuously. This means that even if the physical pixels of an LCD screen are such that there are gaps between the possible shapes, sizes, and colors that the screen can instantiate, and there are a finite number of shapes, sizes, and colors that the screen can instantiate, there is still going to be vagueness at the limits of types. Any means of discretely carving up the property spaces of color, shape, and size has to involve grouping into types what are in fact (subphenomenally) distinct shapes, sizes, and colors, some of which may differ less from adjacent properties grouped into other types. This makes it impossible always to determine unique class membership; hence, finite differentiation is not achieved.
