I never thought about it this way before this term, but one of the central contextual influences on 19th century literature were definitely scientific developments. Geological and evolutionary findings forever changed what human existence meant. God and humanocentrism were not the only things exorcised; economics, labour, romance, love, gender were all utterly reconfigured and re-envisioned. A novel like Tess of the D'Urbevilles can of course on the one hand be read as a tragic novel of love, class, morality, gender, but at the same time it is also about sexual selection, about descent, about a natural world free from humanocentrism. Add into the mix parasciences of race, sexuality, the Occult, medicine, and the mind, and suddenly underneath the texture of 19th century literature can be found bubbling, boiling scientific enterprises, discourses, 'creative misprisions' (as Gillian Beer puts it). Form was equally radically changed. The novel's capacity for evoking lineages and descent as well as narrating large tracts of time was used to express and explore Darwinian ideas; physics gave poetry new modes of sound, rhythm, and lineation. Edgar Allen Poe might have said, in 1829, that science has torn 'from me, | The summer dream beneath the tamarind tree' in 'Sonnet--To Science', but to me, and to those writing after Poe, science seemed to only have made that summer dream infinitely richer.
