A Branched Model for Substantial Motion

Description

This book explores Mulla Sadra's doctrine of *substantial motion*, which posits that substances undergo continuous, intrinsic change rather than merely accidental transformations. It employs modern formal semantics, drawing on the works of Carnap, Bressan, Gupta, and McCall, to model and clarify Sadra's theory. The paper highlights how McCall's branched, four-dimensional framework aligns with Sadra's ideas, offering a structured way to understand identity and change in Islamic philosophy.
