This would seem to indicate that Eros—the love-instinct—is the primary motivation of the id. But Freud notes that, in actuality, the id's compulsion to comply with the love-instinct is actually a manifestation of the pleasure principle, or the tendency to avoid tensions that come with the love-instinct. Complying with the love instinct can sometimes (especially in more primitive animals) give the death-instinct free rein. This concept returns in the following chapter, where Freud suggests that the death-instinct can take up residence in the super-ego.
