Time, time stance, and existence.

Time is analyzed as being those processes by which a system notes the processes which comprise its own existence. The directionality of time is given by the concepts, past, present, and future. To understand the meaning of these concepts, a set of experiments was carried out with four male subjects in which areas of time were expanded or ablated by means of post-hypnotic suggestions. These operations were carried out singly or in combination. The data suggest that the present is primarily associated with stimulus input, the past with the criteria for defining that input as well as the development of response inhibitions and the future with the directionality of that input. Marked personality changes which range from the occurence of catatonic-like states to obsessive types of reaction and manic-like reactions are associated with different combinations of time alterations. Some of the changes are in accord with the serialist position on time of J. W. Dunne. The concept of death is very important both with regard to one’s view of time and how one lives. While it is important to live in the present, the present has no meaning without at least a past or a future. Implications of these findings for psychopathology in general and schizophrenia in particular are considered.
