TY - JOUR A1 - Pajoohandeh, Ali T1 - The riddle of time and space JF - International Forum of Psychoanalysis, Vol. 31 (No. 2, 2022), pp. 108-117. N2 - Time is the most important feature or fundamental describer of normal human experience and is also the most eminent forgotten element of psychoanalysis. Freud believes that the unconscious is timeless and believes that it perceives any given moment as new and immaculate. He makes very little effort to illustrate the origin of time; however, he points to the function of the Pcpt-Cs as the key to this riddle. After him, fewer psychoanalysts can be found who have systemically researched this subject, except for André Green, Hartocolles, Arlow, and Sabbadini. In this paper, I have tried to illustrate how the sense of time is related to libidinal cathexis. I have displayed, through some pathological situations such as melancholy, mania, and schizophrenia, and a clinical vignette, that the more ego invests libido in the objects, the faster we sense the passage of time and the more it withdraws libido from the objects into itself, the slower time passes. Finally, using my previous viewpoint about transitional time objects and phenomena, I have presented some ideas about an object relation account of the origin of the sense of time. Y1 - 2022 ER -
