At the beginning of the 16th century in Germany, religious ends and human a
rt joined forces to produce a sacred rhetoric: a rhetoric that could transf
orm human nature, and explain at the same time how such transformation was
possible according to both science and scripture. No longer was it enough t
o ask in Scholastic fashion 'What is man?' his essence and unique faculties
, his special place in God's world. A new question took on urgency in the w
ake of religious reformation, namely 'What could man become?' But theology
alone could not provide a practical response to this question. Rhetoric, in
its various adopted forms, could. Consequently rhetoric emerged as archite
ctonic of the human sciences in Reformation Germany, shaping pedagogy as a
practical art. Whereas scholars have paid a good deal of attention to the w
ay in which the exact sciences such as mathematics influenced Enlightenment
human science, the history of human science as practical art has received
little attention. This article contributes to such a history by showing how
rhetoric as a practical protreptic art structured human scientific initiat
ives in the wake of Philipp Melanchthon's Reformation pedagogy.
