Across the depth-psychology corpus, ‘Force’ designates far more than a mechanical quantity: it names the generative, sustaining, and transformative power that underlies both cosmological structure and psychological life. Sri Aurobindo provides the most sustained philosophical treatment, arguing in The Life Divine that Force (Shakti) is not alien to Existence but inherent within it — that Consciousness-Force is the very nature of Being, and that all manifest phenomena, from Matter to Mind, are its self-expressions operating at different levels of individualisation. This ontological insistence differentiates Aurobindo from more reductive readings: for him, Force is never merely Prakriti (unintelligent energy) but always the dynamic face of Conscious-Being. Jung’s Red Book introduces a complementary psychological register: human force, when aligned with fullness, is formative and creative, but when combined with emptiness, becomes compulsive and exploitative — a dynamic that maps directly onto depth psychology’s understanding of libidinal displacement. Thomas Moore, reading Ficino, identifies an archetypal Force in Mars: the transhuman energy of conflict and rage that serves as an irreducible element in the soul’s economy. The Stoic tradition (via Hadot’s reading of Marcus Aurelius) stratifies force into vegetative, animal, and rational layers within the human organism. Tension runs throughout between Force as impersonal cosmic principle and as intimate psychological reality — between Shakti and libido, between the World-Force and the individual’s formative capacity.
