Knowledge and Profanation offers numerous instances of profoundly religious polemicists profanizing other religions ad majorem gloriam Dei, as well as sincere adherents of their own religion, whose reflective scholarly undertakings were perceived as profanizing transgressions – occasionally with good reason. In the history of knowledge of religion and profanation unintended consequences often play a decisive role. Can too much knowledge of religion be harmful? Could the profanation of a foreign religion turn out to be a double-edged sword? How much profanating knowledge of other religions could be tolerated in a premodern world? In eleven contributions, internationally renowned scholars analyze cases of learned profanation, committed by scholars ranging from the Italian Renaissance to the early nineteenth century, as well as several antique predecessors. Contributors are: Asaph Ben-Tov, Ulrich Groetsch, Andreas Mahler, Karl Morrison, Martin Mulsow, Anthony Ossa-Richardson, Wolfgang Spickermann, Riccarda Suitner, John Woodbridge, Azzan Yadin, and Holger Zellentin.
