Abstract
The aim of this paper is to present two of the most important critiques that Physics VIII has received. In order to do so, I will draw on two Greek commentators of the corpus who are very well-known due to the sharpness of their critiques to the oeuvre of the Stagirite, as well as due to their deep understanding of it. The first objection that I will look at appears in the commentary to the Physics of John Philoponus, while the second one is taken from an author called the Pseudo-Justin. Before I address them, I will briefly look at the two Aristotelian arguments to which the above objections allude.
