Was there such a person as Lewis Carroll? An affirmative answer is suggested by the thought that Lewis Carroll was Charles Dodgson, and since there was certainly such a person as Charles Dodgson, there was such a person as Lewis Carroll. A negative answer is suggested by the thought that in arguing thus, the two names ‘Lewis Carroll’ and ‘Charles Dodgson’ are being inappropriately treated as though they were completely on a par: a pseudonym is, after all, a false or fictitious name. Perhaps we should say instead that there was really no such person as Lewis Carroll, but that when Charles Dodgson published under that name, he was pretending that there was, and further, pretending that the works in question formed part of the literary output of this pretendedly real individual. Whether or not this is correct for the case of ‘Lewis Carroll’, I will be suggesting that an account of this second style–a fictionalist account, for short–is appropriate for at least a good many pseudonyms. We shall get to reasons why it might nonetheless not be especially appropriate in the present case in due course: one advantage of the ‘Lewis Carroll’/‘Charles Dodgson’ example, such qualms notwithstanding, is that everyone (likely to be reading this) is familiar not only with both names but with which of them is the pseudonym. Another is that, as we shall have occasion to observe below, Dodgson himself had some interesting views on this particular case of pseudonym(it)y.
