The theoretical biologist Waddington drew attention to the damage to scientific progress by COWDUNG – the Conventional Wisdom of the Dominant Group. Despite Popper’s attack on what he called “the bucket theory of science”, that scientific knowledge accumulates incrementally, adding one fact after another, this is now conventional wisdom among biologists. Denis Noble is challenging not only the Neo-Darwinist orthodoxy dominating biology, but revealing the distortions of science produced by this bucket theory of science. The latter is central to (...) understanding the importance of his argument and for seeing the relevance of his work for biosemiotics. (shrink)
