Bertrand Russell said more than once that he was uncomfortable about a conflict, as he saw it, between two things: the strength of the conviction with which he held his ethical beliefs, and the philosophical opinions that he had about the status of those ethical beliefs—opinions which were non-cognitivist, and in some sense subjectivist. Russell felt that, in some way, if he did not think that his ethical beliefs were objective, he had no right to hold them so passionately. This discomfort was not something that Ayer noted or discussed in his account of Russell's moral philosophy and ethical opinions, at least in the book that he wrote for the Modern Masters series (RS). Perhaps this was because it was not a kind of discomfort that Ayer felt himself. His own philosophical views about the status of ethics were at all periods at any rate non-cognitivist, and I think that he did not mind them being called ‘subjectivist’. He did indeed argue that the supposed difference between objectivism and subjectivism in ethics did no work, and that philosophers who took themselves to be objectivists could not achieve anything more than those who admitted they were subjectivists. Ayer based this mainly on the idea that the claims made by objectivists for the factuality, objective truth, and so forth of moral judgments added nothing to those judgments—so far as moral conclusions were concerned, the objectivist was saying the same as the subjectivist but in a louder voice.

While, in this way, he thought that the extra claims of objectivism did no real work, Ayer did not conclude from this that the distinction between subjectivism and objectivism had no content at all.
