ABSTRACT
The case I want to discuss concerns a young man of high intelligence who suffered from severe obsessional neurosis, which disturbed his life to a very great degree. He had various sorts of inhibitions which showed the invasion of symmetrical logic into conscious thinking, in spite of the fact that his reasoning capacity was extremely high. He had successfully passed all his examinations for his Ph.D., in the USA, with the exception of one subject which he postponed indefinitely. He constantly brought into the sessions various blatantly bi-logical reasonings worthy of the most severe schizophrenics, which he obviously was not. I shall concentrate here upon one small detail which, however, clearly illustrates some points about the concept of internal world.
