Abstract
The purpose of this paper is to illustrate the role of some peculiar elements of Aristotle's dialectical development —namely, those emerging in the Sophistical Refutations (SE)— in the analysis and discussion of the Eleatic thesis in Physics I, 2-3. The paper adresses some of Aristotle's preliminary thoughts (Phys. I, 2) (which are read as methodological considerations), and some remarks against Melissus' argument (Phys. I, 3), in order to find connections between such claims and passages of SE, as well as the Topics.
