 On a substantial/non-Pyrrhonian reading, Wittgenstein begins to clarify what kind of philosophically important notion of private language is to be examined, i.e., one that is necessarily private and which refers to one’s immediate private sensations. In the remarks that follow, Wittgenstein argues that the idea of such a private language is nonsensical or incoherent because it is a violation of grammar (i.e., Wittgenstein draws on his substantive views on meaning).
