It is at this stage that we begin to realize the full play of the Counter-Reformation, as against the spirit of science. The movement of mere theological and ecclesiastical heresy had visibly begun to recede in the world of mind, and in its stead, alike in Protestant and in Catholic lands, there was emerging a new activity of scientific research, vaguely menacing to all theistic faith. Kepler represented it in Germany, Harriott and Harvey and Gilbert and Bacon in England; from Italy had come of late the portents of Bruno and Galileo; even Spain yielded the Examen de Ingenios of Huarte (1575), where with due protestation of theism the physicist insists upon natural causation; and now Vanini was exhibiting the same incorrigible zest for a naturalistic explanation of all things. His dialogues are full of such questionings; the mere metaphysic and theosophy of the Amphitheatrum are being superseded by discussions on physical and physiological phenomena. It was for this, doubtless, that the De Arcanis won the special vogue over which the Jesuit Garasse was angrily exclaiming ten years later. [253] Not merely the doubts cast upon sorcery and diabolical possession, but the whole drift, often enough erratic, of the inquiry as to how things in nature came about, caught the curiosity of the time, soon to be stimulated by more potent and better-governed minds than that of the ill-starred Vanini. And for every new inquirer there would be a hostile zealot in the Church, where the anti-intellectual instinct was now so much more potent than it had been in the days before Luther, when heresy was diagnosed only as a danger to revenue. It was with Galileo that there began the practical application of the Copernican theory to astronomy, and, indeed, the decisive demonstration of its truth. With him, accordingly, began the positive rejection of the Copernican theory by the Church; for thus far it had never been officially vetoed--having indeed been generally treated as a wild absurdity. Almost immediately after the publication of Galileo's Sidereus Nuncius (1610) his name is found in the papers of the Inquisition, with that of Cremonini of Padua, as a subject of investigation. [254] The juxtaposition is noteworthy. Cremonini was an Aristotelian, with Averroïst leanings, and reputed an atheist; [255] and it was presumably on this score that the Inquisition was looking into his case. At the same time, as an Aristotelian he was strongly opposed to Galileo, and is said to have been one of those who refused to look through Galileo's telescope. [256] Galileo, on the other hand, was ostensibly a good Catholic; but his discovery of the moons of Jupiter was a signal confirmation of the Copernican theory, and the new status at once given to that made a corresponding commotion in the Church. Thus he had against him both the unbelieving pedants of the schools and the typical priests.
