Footnote 21:

To define anatomy as scientia, and in the next sentence as “natural philosophy,” Siraisi explains, “was to link the status of anatomy to claims, long-established in Latin academic medical tradition, that at least some parts of medicine were subalternated to natural philosophy and qualified as scientia. In the Aristotelian sense of the term, scientia (episteme) was understood to refer to certain knowledge about a distinctly defined subject, achieved by rational demonstrations based on generally accepted premises and leading to universally valid conclusions.” As such, anatomy is more than an ars, whose goals are more immediate and practical. See Siraisi 1994, pp. 65-66.
