ABSTRACT
Logical empiricism, if regarded as having a conception of reason at all, seems to allow only scientific reason and exclude all else as frivolous. In Kantian terms, logical empiricism seems to claim that there is no more to Vernunft than just Verstand: scientific reason is all the reason there is. In Carnap’s case, though, we will see that this first impression is highly misleading, and that his conception of reason allowed for a dialectical combination of practical reason, or in Kantian terms, Vernunft, and scientific reason, that is, Verstand. This chapter outlines the problem and gives a detailed reconstruction of Carnap’s response to it.
