Undetachable Concepts in Non-Human Animals

In this paper, I would like to explore the idea that some non-human animals may be incapable of detaching or separating some of their concepts both from other concepts and from the larger thought contents that they are part of. This, in turn, will make it impossible for them to recombine these undetachable concepts with others in every admissible way. I will begin by distinguishing three different ways in which one concept may be undetachable from others, and I will show how each of them leads to specific restrictions in the kinds of conceptual re-combinations that they admit. Finally, I will try to provide some theoretical reasons, as well as some empirical evidence, to give at least initial support to the hypothesis that some non-human animals actually suffer from the limitations previously identified.
