Abstract

Bartholomaeus Arnoldi (b. c. 1465, d. September 9, 1532) (also called Usingen after his birthplace), began as a philosopher in the via moderna school and later became a member and a theologian of the Order of Augustinian Hermits. Together with Jodocus Trutfetter, he was the most prominent philosopher in Erfurt in the early sixteenth century. Usingen’s main authorities were John Buridan, William of Ockham, Gregory of Rimini, Peter of Ailly, and Gabriel Biel. The focus of his teaching was on a “common view of the via moderna,” which was strongly involved in semantic–metaphysical questions. Usingen stressed the importance of logic as a necessary tool for gaining scientific knowledge, but it was his works on natural philosophy, in particular, that were respected by his contemporaries. In natural philosophy, he generally followed the tradition of Buridan. His discussion on the theory of supposition follows Ockham. On the relationship between theology and philosophy, he strongly posited the unity of truth by allowing certain theological truths a sufficient degree of plausibility as truths in natural philosophy. This view was partly based on Lawrence of Lindores.
