Today we do not expect poems to carry scientifically valid information. But it was not always so. In , Amanda Jo Goldstein returns to the beginnings of the division of labor between literature and science to recover a tradition of Romantic life writing for which poetry was a privileged technique of empirical inquiry. Goldstein puts apparently literary projects, such as William Blake’s poetry of embryogenesis, Goethe’s journals , and Percy Shelley’s “poetry of life,” back into conversation with the openly poetic life sciences of Erasmus Darwin, J. G. Herder, Jean-Baptiste Lamarck, and Étienne Geoffroy Saint-Hilaire. Such poetic sciences, Goldstein argues, share in reviving Lucretius’s to advance a view of biological life as neither self-organized nor autonomous, but rather dependent on the collaborative and symbolic processes that give it viable and recognizable form. They summon for a logic of life resistant to the vitalist stress on self-authorizing power and to make a monumental case for poetry’s role in the perception and communication of empirical realities. The first dedicated study of this mortal and materialist dimension of Romantic biopoetics, opens a through-line between Enlightenment materialisms of nature and Marx’s coming historical materialism.
