Barzun’s critique of the cult of evolutionary theory and the canonisation of Darwin himself is impressive but it is difficult to identify where Barzun stands on the scientific status of evolutionary theory and this is the least convincing part of his work. He appears to be dissatisfied with materialism and determinism without explaining whether he adhered to vitalism, or some form of mysticism or religion. This underlines the problem of pursuing such a wide-ranging research project without the assistance of co-workers, so his reach may have exceeded his grasp at some points. This is especially apparent when he attempted to locate his work in the context of twentieth century physics and biology, where he was operating too far from his base in history and cultural studies.
