First published in 1990. Balzac, Zola and Faulkner all drew upon the principles of evolutionary theory to represent manâs place in nature and his struggle for survival in their major series La Comèdie humaine, Rougon-Macquart and the Yoknapatawpha fiction. This book focuses on the âfirstâ novels in each authorâs series (La Père Goriot, La Fortune des Rougon and Flags in the Dust) and considers how each novel relates to its series and derives a definition of the naturalistic roman-fleuve. To describe this development, the issues of how a scientific idea becomes refracted in a literary genre and how the naturalistic novel developed out of the realistic novel are considered.
