Other intellectual activities may also constitute explanation - but this much certainly does. Ideally, an explained occurrence (0) could have been predicted in a connected way - by extrapolation from prior events (e) via the same laws (L).

Moreover, this loop (0) could have been predicted from such events (e -e ) via the laws of Celestial Mechanics. t 3 This is an ideal situation. It crystallized late in the history of planetary theory.The Greeks found explanations for heavenly motions: the back ward loops were explained to their satisfaction. But they could not predict these motions, not in terms of Attic explanatory cosmologies. | | 出版日期 | Book 1973 | | 关键词 | Aristotle; Medieval Literature; Plato; astronomy; concept | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-010-2498-3 | | isbn_softcover | 978-94-010-2500-3 | | isbn_ebook | 978-94-010-2498-3Series ISSN 0166-6991 Series E-ISSN 2542-8292 | | issn_series | 0166-6991 | | copyright | D.
