Challenging Liberal Representationalism: A Reply to Artiga

Liberal representationalism is the view that even some internal states of very simple organisms like plants or bacteria count as genuine representations. This view has been heavily criticized by many authors, including myself. In a recent paper, Marc Artiga attempts to defend liberal representationalism against these criticisms. One of his main targets is an argument of explanatory exclusion that he ascribes to Burge, Ramsey, Rescorla, Sterelny and me (among others). In this paper, I reply to Artiga by distinguishing the exclusion argument that he focuses on from what is, in my view, the real explanatory challenge for liberal representationalism, and I argue that none of the considerations put forward by Artiga in defense of the liberal view provide an adequate answer to this challenge.
