Ibn Bājjah’s Conception of the Soul and the Reconstruction of Human Psychology

Abstract

This paper offers a comprehensive conceptual exploration of the works of Ibn Bājjah (Avempace, 1085–1138 CE), focusing on his philosophical conception of the soul and its significance for the reconstruction of human psychology. It situates Ibn Bājjah within his intellectual milieu and highlights the breadth of his scholarship across philosophy, medicine, logic, astronomy, and particularly metaphysics and psychology. The goal is to present his model of the soul and self in a clear, systematic way by reading it through epistemological, ontological, axiological, and theological lenses, with attention to how reason (ʿaql), moral action, and remembrance of Allāh relate to human perfection. This conceptual paper is important because Ibn Bājjah remains marginal in contemporary psychological discussions, despite offering a holistic framework that links cognition, ethics, and spirituality rather than treating the mind as value-neutral or purely functional. The paper discusses Ibn Bājjah’s intellectual context, his tripartite theory of the soul (nutritive, animalistic, and rational), the implications of this structure for understanding human behaviour, ethical action, and spiritual refinement. Ibn Bājjah’s analysis of human action as a hierarchical process moving from sensory perception and imagination to desire and rational judgment is highlighted and his contributions contemporary psychology (i.e., positive psychology, social psychology, and cognitive psychology) is articulated. The paper concludes that Ibn Bājjah presents a comprehensive and purpose-driven or teleological view of the study of soul and self (ʿilm al-nafs), where genuine human happiness and fulfilment arise when rational intellect governs desire, allowing the soul to reach intellectual excellence and the ultimate fulfilment lies in knowing and turning toward Allāh.
