The subject of love may not seem an appropriate topic of scientific discourse, for we prefer turning to poetry to learn something meaningsful about love. Nontheless, we find three texts on the subject in Freud´s work, all of which underline an internal division in love. He discussed the contrast between the affectionate and sensual aspects of love, while Lacanian writers have supplemented by pointing to the division between pleasure and desire. This article illustrates these concepts with cases taken from the Danish author Henrik Pontoppidan, one of the most prominent Danish writers from the turn of the 19th century. He is well-known for his novels and short novels. One of these, Nattevagt, from 1894, has been read by critics as a marital conflict between the painter Jørgen Hallager and his fragile wife Ursula Branth, who succumbs to the brutality of her husband. The author supplements this simple version of the story with aspects made visible through the idea of an internal division in sexuality, which Freud elaborated into his theory of the death drive around 1920. By way of introduction, a few words are said about Pontoppidan, focusing on the theme of love in his short novels. Following is a brief summary of the plot of Nattevagt. Finally a more detailed reading of the dialogue between the two protagonists, Jørgen and Ursula, opens the way for a psychoanalytic interpretation of the tragic outcome of their love.
