  Other philosophers remain unimpressed with this naturalistic approach to practical reason. One ground for dissatisfaction with it is the following.  The expressivist strategy relies on an initial contrast between practical reflection on the one hand, and the genuine forms of cognitive activity characteristic of theoretical reasoning on the other. There has to be some important sense in which practical discourse does not satisfy the standards of rationality that distinguish authentic cognitive discourse in the literal sense; otherwise the contention that normative discourse is expressive rather than cognitive will lack any significant content.  But the contrast between theoretical and practical reflection required for this purpose seems elusive. As we saw in section 1 above, theoretical reasoning appears to be no less a normative enterprise than practical reasoning. It is plausibly understood to concern itself with reasons for belief, the evidence and other considerations that speak for and against particular conclusions about the way things are in the world. To the extent this is the case, theoretical and practical reasoning would both seem equally problematic from the naturalistic perspective—assuming, that is, that it leaves no place for such normative considerations as reasons. But if naturalism calls into question the credentials of theoretical reason, it thereby undermines the contrast between genuine reasoning and noncognitive forms of normative and evaluative discourse on which expressivists themselves rely.
