In W. James’s studies the author seeks an answer to the question: What is/For whom is it real? The largest number of interesting suggestions one can find in the 21st chapter of his Principles of Psychology. Many of them are linked with somewhat different, although equally interesting question – when, under what circumstances, are we willing to treat a given “object” as something real. James say, among other things, about direction of attention, about the relation to self, triggering of emotions, and about sensorial values of such objects. The author of the paper emphasizes the current character of the problem of the “perception of realness”. The intuitive solutions and proposals put forward by James can be empirically verified as well.
