BERTOLINI’S PALACE
Naples, Italy. September 12, 1912

Some other day I may answer the part of your letter about psychology: today I am hardly in the mood. You are quite right in saying that we disagree about the existence of unfelt feeling. I am not sure, however, that an unfelt feeling is a fact and not a word. I agree that there is something in an animal before he is aware of it—a very great deal, in fact. This is what I meant by the fact on which we agreed and the words about which we disagreed.
