The Victorian novel was predominantly a novel of domestic manners, not a novel of ideas. As a general rule, Victorian novelists did not give intellectual propositions the status of themes, or employ characters to debate them - unlike later writers such as Thomas Mann or Andre Gide. In fact, Victorian reviewers and readers put serious pressure on novelists to downplay intellectual subjects, which were often regarded as anti-aesthetic. Intellectual life was also considered a male preserve, and intellectual subjects a threat to “masculinize” the novel. The strict separation of private and public spheres in Victorian culture necessarily set the domestic novel apart from intellectual concerns. Nevertheless, an influential branch of intellectual fiction was sustained by a few major Victorian novelists - most notably, George Eliot, George Meredith, and Thomas Hardy. Close attention to the work of these writers (which I will provide later in this chapter) can help define a set of intellectual engagements that were, in fact, broadly shared by other novelists - even if those engagements often took place beneath the surface of domestic fiction, in matters of form and method, or in the intrusion of non-literary discourses, or in novelists' ambivalent fascination with the figure of the intellectual. In fact, intellectual debates informed so many aspects of Victorian fiction so powerfully that it would not be inaccurate to say that those debates governed both the form and the substance of the genre.
