Abstract

Jodocus Trutfetter (also Trutvetter) was a philosopher and theologian of the via moderna, at the University of Erfurt, in the late fifteenth and early sixteenth centuries. His main works include a textbook on logic, the Summule totius logice, and another on natural philosophy, the Summa in totam physicen. As a proponent of the via moderna, Trutfetter stressed the importance of taking both ancient and modern authorities into account. In questions concerning universals, categories, and psychology, his views were close to those of John Buridan. On the relationship between theology and philosophy he shared, for the most part, William of Ockham’s position.
