Abstract

Metaphysics, one of the most venerable branches of philosophy, investigates the fundamental nature of being and existence, as well as the structure and laws of reality. This field, significantly shaped by the works of Plato and Aristotle, attributes truth either to universals (Plato’s perspective) or to the essences of particulars (Aristotle’s perspective). This paper explores Neo-Aristotelian metaphysics, integrating and reinterpreting Aristotle’s classical metaphysical understanding in contemporary philosophical discussions. Neo-Aristotelian metaphysics reconfigures Aristotle’s classical concepts in light of modern scientific and philosophical developments. In this context, the approaches of Ellis’s "Scientific Essentialism," Oderberg’s "Real Essentialism," and Bird’s "Dispositional Essentialism" are examined. Dispositional essentialism posits that the essences of entities can be defined by their dispositions and capacities. Alexander Bird argues that natural laws reflect the dispositions of entities, explaining how entities behave under certain conditions. Neo-Aristotelian metaphysics bridges metaphysical realism and naturalism by emphasizing the essences and natures of entities. This paper investigates the principles of dispositional essentialism and Neo-Aristotelian metaphysics, highlighting their contributions and significance in contemporary metaphysical debates. Furthermore, it underscores that the prominence of these approaches today results from their successful integration of modern scientific findings with classical metaphysical principles. By focusing on the essences and potentialities of entities, Neo-Aristotelian metaphysics and dispositional essentialism offer a more comprehensive and coherent metaphysical perspective. These approaches reflect modern philosophy's dynamic nature while revealing classical thought's timeless value.
