ABSTRACT
It is difficult for all of us who practise psychoanalysis to realize how obscure this subject is to people who are not used to attaching any importance to the problems of thought, or who are not used to thinking at all. In the psychoanalytic world we have our own divisions of time; we talk about periods like infancy childhood, adolescence, middle age, old age, puberty, and so on. All that is so familiar to us that it is hard to realize that there are many people who are not familiar with those ways of marking the passage of time.
