  We have seen that there are various choice points for how to develop a presuppositional account of category mistakes. It might be thought to be an advantage of the presuppositional account of category mistakes (on any of its versions) that it utilizes an independently motivated linguistic theory. However, a significant disadvantage of utilizing such a theory is that it makes it harder for the presuppositional approach to account for what is distinctive about the infelicity of category mistakes, i.e., what distinguishes their infelicity from other cases of presupposition failure and explains why category mistakes  form a distinctive and unified phenomenon (cf.  §1).[30]
