The presented volume contains a critical edition of questions 8–10 from Book II of the commentary on Peter Lombard’s Sentences by Marsilius of Inghen († 1396). Marsilius was a famous scholar and the first rector of the University of Heidelberg, educated in Paris. He influenced next generations of philosophers and theologians up to sixteenth century. In general, these questions deal with the problem of creation of the material world. In detail, question 8 addresses the issue of formless matter and the material nature of the heaven. Question 9 addresses the concept of light and some trinitarian problems. Finally question 10 explores the model of the universe and the approach to the relationship between faith and reason.
