"I urge that we turn Kuhn on his head and demonstrate that a paradigm is nothing more than an arrested social development." (K402) Notwithstanding the long debate to which The Structure of Scientific Revolutions has given rise since its publication in 1962, this quote from Steve Fuller's assessment of its author's legacy suggests an original if controversial project: may a better understanding of science arise from the ashes of idealist historicism! Yet rather than furnish the Marx to Kuhn's Hegel, Fuller but manages a pastiche of Proudhon, as it were, which calls for another inversion of titles as rejoinder in turn. There can be no doubt that some very important issues are raised in this book, but just as this reader's expectations were dashed in its course, so the issues end.up curiously diminished; given the significance of the subject matter, it is of interest to find out why.
