 The arguments for deciding between these two positions involve a mixture of theoretical and empirical considerations. Proponents of the first view have claimed that language is ambiguous in ways that thought presumably is not. For example, the natural language sentence everyone loves someone could be interpreted to mean that for each person, there is some person that they love, or to mean that everyone loves one and the same person (Pinker 1994). Proponents of the first view have also argued that since language itself has to be learned, thought is prior to language (Fodor 1975; Pinker 1994). A third and similar consideration is that people seem to be able formulate novel concepts which are given a linguistic label later; the concept comes first, the linguistic label second (Pinker 1994).
