The article on my theory of descriptions by Mr. Lejewski raises two points. One is as to the copula. I do not quite understand why it is thought that an ambiguity in the meaning of the word “is” is relevant in regard to my theory of descriptions. There are many problems in regard to which it is relevant. I have mentioned one of these in criticizing Hegel in Our Knowledge of the External World on p. 39n of the original edition (1914). But, although I have read Mr. Lejewski's argument several times, it still seems to me quite clear that in “Scott is the author of Waverley” the “is” is that of identity. Nor have I been able to understand why he considers his theory of descriptions preferable to mine. I am, however, quite willing to believe (and I say this in all sincerity) that there is some point that I have missed in his discussion.
