The Functions of Moral Philosophy: A Plea for an Integration of Philosophical Analysis and Empirical Research.
Oslo University Press, Oslo 1958, stor 8vo, orig. omslag, 45 s., engelsk tekst.
«It has been argued that moral philosophy is not concerned with emirical problems because ethical language cannot be translated into a so-called naturalistic language. This argument, however, confuses object-language and meta-language. Even if it is true that the object-language of meta-ethics is so-called non-naturalistic, some of our statements about sentences in this language may be empirical. Furthermore, meta-ethics is not the whole of moral philospphy. Strategy-research, for instance, has clearly empirical components.» — 38
