These (though never intended for delivery) are cast in his lively, rhetorical manner of speech, and in places they recapitulate his established views (as, for instance, about dreams). But Freud also develops very fully here his newer concepts of id, ego and super-ego as elements in the structure of the mind, and explains his more recent conclusions about anxiety and the instincts and about the psychology of women. In addition he applies his analytical method to such phenomena as telepathy and communism, among a number of subjects of indirect relevance to psychoanalysis.
