Summary of argument to this point

So far I have established the following.

i.

That, pace Dummett, there are three categories for classification of what might be called `skills.'

ii.

That of these three, only two (C2 and C3) are properly described as concerning rule-governed behaviors.

iii.

That one of these two categories (C2) does not require that practitioners have any theoretical knowledge, either explicit or implicit, of the rules or criteria.

1. A corollary of this is that analogues of Dummett's M4 and M5 do not characterize skills in general. While C3 skills may satisfy M4 and M5, or analogues of them, along with the proposed condition 4 (§3.3), C2 skills do not
   

iv.

That there is at least one member of C2, viz., controlled counting.

In the next section I argue that along with controlled counting, language belongs in C2.
