Cardano, a Dignidade e Influência Astrológica e o Espírito Crítico: Exemplo Textual


Ernst, G. 2001, “ ‘Veritatis amor dulcissimus’: Aspects of Cardano’s Astrology” in Secrets of Nature: Astrology and Alchemy in Early Modern Europe, 48-9.

  Cardano felt compelled to admit that the situation was genuinely difficult and that the critics of astrology had it all too easy. The discipline had in fact been discredited and corrupted, and by its own practitioners. Cardano condemned not the art, but the artisans: they were the ones who failed to bring to its study the attention, effort, and mental profundity a discipline of its nobility and difficulty required. Moved either by greed or by ambition, they claimed to possess knowledge that they did not have and promised to give answers that an astrologer could not provide. They continually invented new expedients, taking shameless advantage of the ambiguous and profitable area of “elections and interrogations.” One particularly greedy and ignorant astrologer, for example, had forced Ludovico Sforza to follow minute rules, even making him and his courtiers ride horseback in rain and mud. 

   Astrology, Cardano admitted, was not an “absolutely precise” form of knowledge, endowed with absolute certainty and rigor. But that did not mean that it was “a superstition, a form of prophecy, magic, vanity, an oracle or a presage.” It was a natural, conjectural art that set out to formulate probable judgments about future events. There was no reason to deny the legitimacy of doing so, especially when it was granted to doctors, sailors, farmers, and miners. 

   The one basic presupposition on which astrology rested was the reality of the influence that the celestial bodies exercised on the sublunary world.These influences, obvious in the case of the sun and the moon, which werethe supreme rulers of the life of the universe, undeniably also belonged by extension to the planets and the stars, which had the same basic nature. Cardano discussed the question of these influences at length. He tried bothto prove their existence, with a plethora of examples, and to identify the paths by which they were propagated and the ways in which they affected the sublunary world. Only repeated observations could provide the basis for a body of theory as elaborate as that of Ptolemy, which could be confirmed, enlarged, and corrected in its turn by the observation of further facts.
