History of Ideas Club: The Copernican Revolution in Astronomy

Send us Fan MailCopernicus demonstrated for the first time that the Earth orbits the sun, and not the reverse as was previously thought. Previous measurements had lended themselves to the latter view, but the number of 'epicycles' needed to model the known orbits and their coincidence at specific times became impractical. Copernicus' revision of the fundamental point of reference simplied the model drastically. More importantly it challenged our peceived sense of central significance in the cosmos, a kind of demystification of the place of man in the universe. Copernicus' work influenced Gallileio, and both astronomers' works were censored by the Church, not exactly because of the apparent contradiction with scripture, as is often claimed, but because of the competing epistemologies: the nature and scope of scientific truth in relation to philosophical and theological truth was not yet understood. We examine the deep philosophical and anthropological conflict underlying this important episode in modern history.
