 Abner wrote his criticism of Artistotelian science at the beginning of the 14th century, approximately the same time that Ockham wrote his criticism of this science. In the writing and the thought of Abner we do not see any kind of influence of Ockham or of other late scholastics (the only scholastic philosopher that he cites is Thomas Aquinas and there are no quotations from Christian sources on a scientific subject). It is interesting to note that the systematic criticism of Aristotelian science started approximately at the same time in the Jewish milieu (with the writings of Abner) and in the Christian milieu, with probably no relation one to the other.
