A Nascent Realist Theory of the Laws of Nature Based on the Doctrine of “Motion in Substance” from Late Islamic Philosophy 41 68 3754 10.22091/jptr.2025.12528.3262 FA Masoud Toossi Saeidi PhD in Philosophy of Religion, Assistant Professor of Institute for Science and Technology Studies, Shahid Beheshti University, Tehran, Iran. 0000-0001-8394-8507 Seyed Hasan Hosseini Professor of Philosophy of Science Department, Sharif University of Technology, Tehran, Iran. 0000-0002-0196-3680 Journal Article 2025 03 09 This paper proposes a distinct realist perspective on the laws of nature, rooted in the tradition of late Islamic philosophy, which may offer a new solution to one of the difficult challenges of scientific realism, termed the ‘Central Dilemma’ by Mumford. It begins with a brief introduction to the problem of scientific realism concerning the concept of the laws of nature. Then, in the first part, we compare the realist theories of the laws of nature developed by Lewis, Armstrong, and Bird, focusing on their account of the three key concepts of causation, necessity, and law. Based on this analysis, the second part formulates a new realist theory, drawing from the doctrine of “Motion in Substance” from Late Islamic Philosophy, particularly the philosophical thought of Tabatabai. This will be done by extending the idea of motion in substance and examining some of its implications. This new account is, in some respects, similar to Bird’s view, yet in other respects Humean and similar to Lewis’s. By comparing this new approach with the aforementioned three theories, concerning their accounts of causation, necessity, and law in relation to the ‘Central Dilemma’ challenge, we conclude that it could bring a new vision that could potentially resolve this challenge.
