Beyond the Pleasure Principle by Sigmund Freud

IN the psycho-analytical theory of the mind we take it for granted that the course of mental processes is automatically regulated by ‘the pleasure-principle': that is to say, we believe that any given process originates in an unpleasant state of tension and thereupon determines for itself such a path that its ultimate issue coincides with a relaxation of this tension, i. e. with avoidance of ‘pain' or with production of pleasure. When we consider the psychic processes under observation in reference to such a sequence we are introducing into our work the economic point of view. In our opinion a presentation which seeks to estimate, not only the topographical and dynamic, but also the economic element is the most complete that we can at present imagine, and deserves to be distinguished by the term meta-psychological.

We are not interested in examining how far in our assertion of the pleasure-principle we have approached to or adopted any given philosophical system historically established. Our approach to such speculative hypotheses is by way of our endeavour to describe and account for the facts falling within our daily sphere of observation. Priority and originality are not among the aims which psycho-analysis sets itself, and the impressions on which the statement of this principle is founded are of so unmistakable a kind that it is scarcely possible to overlook them. On the other hand, we should willingly acknowledge our indebtedness to any philosophical or psychological theory that could tell us the meaning of these feelings of pleasure and ‘pain' which affect us so powerfully. Unfortunately no theory of any value is forthcoming.
