Goethe as a novelist is best known for two earlier novels, The Sorrows of Young Werther (1774) and Wilhelm Meister’s Apprenticeship (1796). But Elective Affinities, which was published in 1809, is widely regarded as his mature masterpiece, not least because of its unusual provenance, which brings together Goethe the scientist as well as Goethe the writer. Baron Eduard and his second wife Charlotte enjoy a quiet, humdrum existence in their opulent castle, but when he invites his friend the Captain and she invites her niece Ottilie to stay with them, their lives are turned inside out as both hosts begin to feel attracted to their guests. Using one of the chemistry theories of the time (the term ‘elective affinities’ was used by Robert Boyle and Isaac Newton) as a metaphor throughout the novel, Goethe juxtaposes social interactions with scientific principles, while illustrating the typically Romantic concern of the individual coming to terms with society. Controversial when first published and still much critically debated today, Goethe s Elective Affinities is an early model for the modern novel.
