Amitav Ghosh S The Shadow Lines Critical Essays
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.

That means that Popper’s falsifiability criterion was not really a definition of science (he was not into definitions!) but a proposal to adopt a critical attitude towards theories and especially to check whether they were open to empirical testing. It was a proposal or a convention and its merit was to be judged by its helpfulness in coming to grips with problems in the theory of knowledge (and the practice of scientist). As for being timeless and a priori, Popper noted that there are degrees of testability (so the line of demarcation is not sharp) and the testability of particular theories will change with progress in theory and experimental technology.
What do the cases do for our appraisal of Bayesian subjectivism? The Dorling example is very impressive on both aspects of the Lakatos scheme – swallowing an anomaly and thriving on a confirmation. The case for Bayesianism (and Lakatos) is reinforced by the fact that Dorling set out to criticise Lakatos, not to praise him. And he remained critical of any attempt to sidestep refutations because he did not accept that his findings provided any justification for ignoring refutations, along the lines of ‘anything goes’.
