Thesis on Mathematical Definition and Dialectical Refutation. Aristotle’s Criticism of the Foundations of Mathematics
In my dissertation, I reconstruct the ways in which ancient philosophers criticise principles of mathematical proof, especially definitions. In order to explore the interrelations between the philosophical theory and the actual practice of mathematical definition, I also examine to what extent these criticisms are reflected in ancient mathematical works. The focus of my dissertation lies in Aristotle’s theory of definition in the Organon and Euclid’s Elements. In the Topics, Aristotle launches a major attack on the foundations of ancient mathematics, insofar as these foundations concern definitions. He provides a deductive method to test whether a given pair of terms is a definition or not and illustrates this procedure with contemporary mathematical examples. Book VI of the Topics contains a series of dialectical arguments to refute putative definitions of fundamental geometrical items such as point, line, plane, solid, and finite straight-line, as well as of the arithmetical terms odd and even.
Many of the ancient mathematical definitions do not in fact meet Aristotle’s requirements for adequate definition. The question arises whether, or to what extent, the tensions between Aristotle’s theory and the ancient practice of defining can be harmonised. Moreover, some of the definitions that Aristotle rejects in the Topics have been expressly restated and deductively employed as premisses in mathematical proofs in Euclid’s Elements. This gives rise to the deeper question concerning the objective and outcome of overthrowing an established definition, especially if it appears to serve its purpose as an explanatory principle in scientific demonstration. Why should a mathematician care about dialectical arguments against mathematical principles? How seriously should we take Aristotle’s tests and rules in the Topics? Should they actually make us worried about the foundations of mathematics?
CV
Benjamin Wilck is a doctoral candidate in the RTG Philosophy, Science and the Sciences of the Graduate Program in Ancient Philosophy of Humboldt University Berlin. His doctoral supervisors are Professor Jonathan Beere (Berlin / Princeton), Professor Stephen Menn (Montréal), and Professor Benjamin Morison (Princeton). After a successful career in high-performance swimming, Benjamin studied Philosophy, Cultural Studies, and Aesthetics in Berlin and Paris. In March 2014, he received a Magister Artium with honours from Humboldt University Berlin. In his M.A. dissertation, he enquired into the explanatory status of metaphysical arguments by discussing the question whether Aristotelian metaphysics is a demonstrative science. His research interests encompass Ancient Philosophy (especially Ancient Logic) and Ancient Mathematics as well as Philosophical Logic, History of Logic, and Metaphysics.
