"The Kempton-Wace Letters" by Jack London and Anna Strunsky Walling is an epistolary novel published in 1903. Written anonymously, the work presents a philosophical debate about love and sex through correspondence between two contrasting characters: a young scientist who views romance through a Darwinian lens, and an elderly poet who champions emotion and feeling. Their exchange explores whether love should be governed by rational analysis or passionate sentiment, reflecting tensions between scientific materialism and romantic idealism at the turn of the twentieth century.
