ABSTRACT
…“painful feelings are connected with an increase and pleasurable feelings with a decrease in stimulation. Let us, however, be careful to preserve this assumption in its present highly indefinite form, until we succeed, if that is possible, in discovering what sort of relation exists between pleasure and ‘pain,’ on the one hand, and fluctuations in the qualities of stimuli affecting mental life, on the other (Freud, 1915a, p. 64).
