Abstract
In a number of articles, Hans-Johann Glock has argued against the »lingualist« view that higher mental capacities are a prerogative of language-users. He has defended the »assimilationist« claim that the mental capacities of humans and of non-human animals differ only in degree. In the paper under discussion, Glock argues that animals are capable of acting for reasons, provided that reasons are construed along the lines of the new »objectivist« theory of practical reasons. The paper critizices these views.
