William James was one of the most frequently cited authors in Wittgenstein’s Philosophical Investigations, but the attention paid to James’s Principles of Psycho- logy in that work is typically explained in terms of James having ‘committed in a clear, exemplary manner, fundamental errors in the philosophy of mind.’ (Goodman 2002, p. viii.) The most notable of these ‘errors’ was James’s purported commitment to a conception of language as ‘private’. Commentators standardly treat James as committed to a conception of language as private, and the most notorious instance of this commitment can purportedly be found in his discussion of the feelings associated with logical terms like ‘and’, ‘if ’ and ‘but’ in the Principles’s chapter, ‘The Stream of Thought’. However, the received view stands in need of serious re-evaluation. In particular, there is little reason to think that James’s notorious discussion of the ‘if-feeling’ should be understood as an attempt to give an account of the meaning of ‘if ’ (indeed, there is little reason to even think that Wittgenstein interpreted him this way). The picture of our ideas developed in ‘The Stream of Thought’ sits badly with any theory that identifies meanings with ideas in this way, and while James’s chapter on ‘Conception’ (as well as some portions of Some Problems of Philosophy) has also been portrayed as committing James to the in principle privacy of language, it will be argued here that James’s account of our ‘conceptions’ is radically different from that of the private linguist.
