The will to power stands as one of the most contested and generative concepts traversing the depth-psychology corpus. In its Nietzschean origin — formulated most lyrically in Thus Spoke Zarathustra and elaborated through On the Genealogy of Morals — it names the single motivating principle underlying all human striving: not merely domination of others, but the fundamental drive toward self-overcoming, the sublimation of primitive aggression into self-command, and the ceaseless creation of values. Jung’s engagement with the concept is decisive for depth psychology: in Two Essays on Analytical Psychology, he refuses Freud’s subordination of the power drive to Eros, insisting that the will to power is ‘just as mighty a daemon as Eros, and just as old and original.’ For Jung, the collision with the shadow in Nietzsche’s case revealed the power instinct as a genuine unconscious force, not a secondary formation. James Hillman, approaching power through a post-Jungian archetypal lens, interrogates the heroic and domination-centred models that have historically defined power discourse, arguing for subtler, soul-indexed modes. Angela Hobbs traces structural parallels between Nietzsche’s will to power and the Platonic thumos, illuminating deep continuities in Western accounts of the drive toward self-achievement. The concept thus radiates outward — through self-overcoming, sublimation, shadow, Superman, and the critique of slave morality — touching virtually every major question in depth-psychological anthropology.
