Alternatively, the claim might be about reason: that all (practical) reason is, in some sense, instrumental.  On one interpretation, the claim would say that the only true claim about reason is some principle of instrumental transmission.  But this would seem to imply that there are no practical reasons at all. Unless there is some other true claim about reasons for “ends” understood as actions, there is nothing to be transmitted.  (For arguments that there would need to be another kind of rationality, see Korsgaard 1997; Lavin 2004; Hubin 1999; Nozick 1993; Hampton 1998.)
