Portrait of Sigmund Freud Sigmund Freud Dream Psychology — Chapter 8. The Primary and Secondary Process-Regression (1920)

The system cannot do anything but wish. If this remained so the mental activity of the second system, which should have at its disposal all the memories stored up by experiences, would be hindered. But two ways are now opened: the work of the second system either frees itself completely from the principle of pain and continues its course, paying no heed to the painful reminiscence, or it contrives to occupy the painful memory in such a manner as to preclude the liberation of pain.

I show by another point for what purpose the second system is obliged to correct the primary process. The primary process strives for a discharge of the excitement in order to establish a perception identity with the sum of excitement thus gathered; the secondary process has abandoned this intention and undertaken instead the task of bringing about a thought identity. All thinking is only a circuitous path from the memory of gratification taken as an end-presentation to the identical occupation of the same memory, which is again to be attained on the track of the motor experiences.
