After a scientific career that ended in dishonour, C. P. Snow turned to writing and became a very successful (but hardly great) novelist. Snow used his experience of the scientific and literary worlds in developing his most famous argument of the existence of two mutually largely exclusive cultures in academia. Stefan Collini's introduction to C. P. Snow's classic lecture is invaluable, placing it in the context of the broader 'culture wars' of the Modern era. Snow was clearly on the side of the industrial-scientific revolution, and although he was a successful novelist, he clearly felt scientific ignorance was far worse than ignorance of the arts. This invited strong opposition from conservative critics of the emerging mass society, which placed a far higher premium on developing technical skills than human graces. 'The Two Cultures' thus drew a famously vitriolic attack from the literary critic F. R. Leavis who, amongst other things, characterized Snow as an 'intellectual nullity'. The clash was one in a series of battles since the Industrial Revolution, including 'the Romantic versus the Utilitarian, Coleridge versus Bentham, Arnold versus Huxley' (p. xxxv), and others.
