Thomas Bradwardine's theological treatise De Causa Dei provides a valu
able source for late medieval views on the relationship between scienc
e and religion. Bradwardine, who can be seen as belonging in a traditi
on deriving from Roger Bacon, was strongly impressed by the impotence
of human reason in dealing with an apparent infinitude of facts, and a
ccordingly stressed both ancient authority and prophetic revelation as
appropriate sources of scientific knowledge. Two particularly importa
nt ancient works for him were the pseudo-Aristotelian Secretum Secreto
rum and De Mundo. The latter led him to an arresting image of the univ
erse as a magnetically driven clock.
