Physics, neo-thomism and mosaic cosmogony at the roman college: the case of the jesuit Giambattista Pianciani

Preliminary the figure of Abbot Feliciano Scarpellini and the scientific environment in Rome in the first half of the XIX century are introduced. It is then analysed the life and work of the physicist and philosopher Giambattista Pianciani (1784-1862) of the Society of Jesus. Pianciani was in Rome among the most peculiar representatives of that cultural program aimed at countering the theses of Enlightenment materialism through a process of conciliation and justification of scientific discoveries with Catholic doctrine. This apologetic and concordist program started under Pius VII, also continued during the pontificate of Leo XVI. In the wake of this peculiar apologetic program, the controversy that, around the mid-nineteenth century, arose in the Roman College between neotomists and some scientists of the order, for example, Angelo Secchi, is also discussed. Finally, the specific concordist program developed by Pianciani is discussed. This program aimed to reconcile the biblical account of the world’s creation with the scientific results that came from the studies of natural cosmogony.
