  The first question of Book I of the Lectura, is “Whether the wayfarer can know that God exists by means of philosophical proof,” and a number of arguments are presented, six against and six for. He tells us how he will deal with the problem: firstly, he will deal with the question as to whether the existence of God as such can be known and then, secondly, whether one can have both faith and knowledge of the same thing at the same time. Then, thirdly, he will examine the various authorities. This is the basic structure followed in the rest of the Lectura, even if FitzRalph did not always reorganize his material fully in this manner, since sometimes individual articles remain on their own or questions are left unresolved. FitzRalph quotes the views of Henry of Ghent on demonstrating the existence of God, but he accepts the position of Aquinas. Again, regarding whether God’s existence is evident or not, he follows Aquinas. There then follows a long and elaborate treatment of the ontological argument but, curiously, no form of a cosmological argument is to be found in his writings.  It must be surmised that the latter was not the focus of debate in Oxford at this time.
