Thomas Kuhn's, book The Copernican Revolution deserves to be regarded as the best of that small group of longue duree histories that mark postwar historiography of science. In many respects, it is probably the single most influential one. Tightly written and brilliantly argued, it is responsible, together with The Structure of Scientific Revolutions, for the continued popularity of the metaphor of revolution in science among scholars and students alike. Yet, surprisingly, while aspects of the story conceived in Kuhn's original account (...) have been debated, researched, and considerably revised, his overall understanding of a scientific revolution initiated by Copernicus has received no detailed scrutiny. The same may be said of the deployment of Copernican episode in Structure. Finally, a critical appreciation is in order not least because Kuhn's story is so compact and his language at times metaphorical. (shrink)

Summary The Copernican system was condemned as heretical by a decree of the Roman Inquisition in 1633. This decree was effectively, though not officially, withdrawn in 1757, after which date Catholic astronomers felt themselves free to accept and propagate the system without reserve. Between these dates their attitudes varied greatly. In France the decree was never promulgated and was legally unenforceable. Astronomers could be Copernican without any fear of consequences and most of them were, though some, out of respect for (...) the Church, refrained from declaring themselves publicly. In Italy the possible risks were greater, but a few Copernican or near-Copernican works were published without hostile reactions. The ecclesiastical authorities were tolerant and made little positive effort to enforce conformity. By 1744, the system was being freely propagated in Rome itself. (shrink)
