 Consider a concrete example (Conee &amp; Feldman 1998): Smith sees a maple tree outside his window one sunny afternoon and forms the belief that there is a maple tree near his house. How should we type his belief-forming process? Is the relevant type vision? Or perhaps something more fine-grained, such as visual experience of a maple tree on a sunny afternoon? Or is it something more coarse-grained, such as perception? The worry is that Smith’s token belief-forming process seems to instantiate all these process types (and many more). So singling out any single one of them as the “right” way of typing the process seems arbitrary.
