Between Justice and Judgment: An Analysis of Free Will in Mu'tazilism

The Mu’tazila were a group of early Islamic rationalists whose primary philosophical project was to reconcile God’s perfectly just nature, as well as the existence of a judgment day, with human free will. Drawing on Greek logical precepts, the Mu’tazila rejected the idea that human actions were caused solely by God, thereby affirming that humans have at least some degree of originative power. In this thesis, I will present a logical analysis of the Mu’tazila’s rejection of determinism, as well as their position on human-originated action, primarily using Qadi Abd al-Jabbar’s Book of the Five Principles as my source text. I will then present some of the primary views in contemporary free will discourse and compare these views to those of the Mu’tazila. The aim of my thesis is to present a logically rigorous picture of free will under Mu’tazilism, as well as to highlight the relevance of Mu’tazilism within contemporary discussions of free will.
