Love is one of the oldest themes in literature and philosophy. Many works and studies have been dedicated to understanding its origin and essence, yet one aspect has remained largely overlooked, namely, the temporality of love. This paper seeks to understand how romantic love is constituted through a complex temporal structure in which past, present, and future relate to each other in a non-linear narrative movement. More specifically, it argues that love is an ongoing process, whereby lovers commonly create and narrate a memory of the past that gives meaning to their love. The content of this shared memory relates to some primordial unity in which they were parts of a greater whole. This past memory is projected into the future as a state that should be retrieved; the movement forward is thus conditioned by the movement backward, and conditions it in turn. My hypothesis is that love consists of a dual temporal movement, backward and forward, using memory as a driving force that is neither static nor objective; rather, it must be created and recreated through constant narration for love to endure. To develop my proposal, I draw first on Plato’s theory of love as recollection, and Kierkegaard’s theory of love as repetition. I then briefly turn to two works from the twentieth century, namely, Marcel Proust’s Swann in Love and Marguerite Duras’s Blue Eyes, Black Hair. These will serve as test cases for my theory of love as shared memory, emphasizing the role that narration plays in it.
