 So, practical modes of representation are hard to escape if intellectualism is to be defended against the sufficiency objection. To assuage concerns about the intelligibility of practical modes of presentation, Pavese (2015b) proposes we think of them along the lines of practical senses, which in turn can be modeled after computer programs. Programs determine an output, just like Fregean senses determine a referent; and they are practical in that they break down a task into the smallest parts that the system can execute (the primitive operations of the system as well as into primitive ways of combining those parts) so they ground the ability to perform a complex task in terms of the ability to perform all of its parts. On this view, if one represents a task practically, one represents all of its parts, and the combination of those parts, through instructions that one has the ability to execute. So representing practically a task entails that one has the ability to perform the corresponding task. (For a critical discussion of practical ways of thinking, see Mosdell 2019. Habgood-Coote 2018c argues that the classical generality problem for reliabilism (Feldman 1985; Conee &amp; Feldman 1998) arises for intellectualism.)
