Abstract
In this paper I examine Davidson’s argument from referential opacity against the attribution of thoughts to non-linguistics animals. I will begin by reconstructing the strongest version of the argument — i.e., the one which is better suited to overcome the different objections that have been raised against it. Once that is done, I will also object this version arguing, in a nutshell, that the fact that non-human animals lack language does not preclude us from acquiring some knowledge of their mental contents. Thus, I conclude that the argument from referential opacity fails to support Davidson’s radical skepticism regarding the possibility of acquiring knowledge of the mental contents of non-linguistic animals, and of legitimately attributing intentional mental states to them.
