The aim of the present edition is to make two texts available which can throw

some more light on the role of Aristotle's Metaphysics in 14th-15th academic teaching.

One of them contains part of an early (hitherto unknown) version of John

Buridan's Questions on Metaphysics , the other is a 15th century abbreviation of precisely

this early version. Remarkably, both texts belong to the East European tradition

of Buridan's works, which is the more interesting as they testify to the master's

earlier activities as a Parisian teacher on the subject of metaphysics. In particular,

they elucidate Buridan's ongoing semantic approach to matters of metaphysics

and ontology as well as his attitude to Aristotle's authority.
