Toward the Soul: An Inquiry into the Meaning of Psyche before Plato

The Word “Psyche” Had to Be Constructed, Not Discovered—and Every Psychology Since Inherits That Construction

David B. Claus’s Toward the Soul is a work of classical philology that functions, whether it intends to or not, as a depth charge beneath the foundations of depth psychology itself. Claus tracks the semantic history of the Greek word psyche from its earliest appearances in Homer through lyric poetry, tragedy, and the pre-Socratic philosophers, arriving at the threshold of Plato. His central demonstration is devastating in its simplicity: the word psyche did not carry a stable, unified meaning across the archaic and classical periods. In Homer, psyche is primarily the life-breath that departs the body at death and persists as a witless shade in Hades—it has no cognitive function, no emotional valence, no interiority. It is emphatically not the “soul” of later philosophy. The terms that do the psychological work in Homer—thumos, noos, phrenes—operate as organs of feeling, perception, and decision, yet none of them becomes the master concept. Claus shows that psyche only gradually absorbs the functions of these other terms across centuries of literary and philosophical development, culminating in the Platonic synthesis that treats psyche as the seat of reason, emotion, appetite, moral agency, and immortality simultaneously. This synthesis was an achievement, not a given. Every psychology that appeals to “psyche” as its root concept—from Aristotle to Ficino to Hillman—is therefore building on an artificial consolidation whose seams Claus meticulously exposes.

Hillman’s Heraclitean Origin Story for Depth Psychology Rests on a Philological Anachronism

James Hillman, in Re-Visioning Psychology, traces the lineage of depth psychology to Heraclitus, specifically to the fragment “You could not discover the limits of the soul, even if you traveled every road to do so; such is the depth of its meaning.” Hillman reads this as the founding gesture of a psychology of interiority, a recognition that soul possesses unfathomable depth. Claus’s philological analysis disrupts this reading at its foundation. For Claus, Heraclitus’s use of psyche is still embedded in a cosmological frame where psyche denotes something closer to a vital substance participating in elemental transformation—fire, water, the dry and the moist—than to the rich, image-laden interiority Hillman requires. The bathun (depth) Heraclitus attributes to psyche’s logos may refer not to psychological profundity in the modern sense but to the inexhaustibility of a cosmic principle’s rational structure. Hillman needs Heraclitus to have already meant what Plotinus and Ficino would later mean by soul, but Claus shows that the semantic field was not yet prepared for such freight. This does not invalidate Hillman’s archetypal project—Hillman himself acknowledges he is doing psychology, not philology—but it does reveal that the “ancestral tree” claimed in Re-Visioning Psychology is partly a mythic construction, a genealogy that serves rhetorical and imaginative purposes rather than historical ones. The distinction matters because it exposes how depth psychology, in claiming ancient authority, sometimes replaces philological precision with what Hillman would call “seeing through”—except here it is the tradition itself that requires seeing through.

The Pre-Platonic Psyche Was Not Interior—and This Absence Reframes What Edinger Calls “the Psyche in Antiquity”

Edward Edinger’s The Psyche in Antiquity proceeds from the assumption that early Greek philosophers were articulating experiences of the collective unconscious, that their cosmological speculations mirror archetypal structures accessible in modern dreams and analysis. Claus’s work provides the missing philological discipline that Edinger’s Jungian amplification lacks. Where Edinger reads Thales’s water, Heraclitus’s fire, and Empedocles’s love and strife as symbols of psychic processes, Claus insists that the archaic Greeks had no concept of psychic interiority in which such symbolism could lodge. The psyche of Homer is not an inner world; it is a quasi-physical entity that occupies no interior space during life and becomes a pale copy of the person only after death. The thumos rages, the noos perceives, the phrenes contain thought—but these are localized, often organ-based functions, not facets of a unified self reflecting on its own depths. Claus’s insistence on this point is not mere pedantry; it forces a reckoning with the degree to which Jungian readings of antiquity project modern psychological categories backward onto material that resists them. Edinger’s approach is valuable as amplification—Jung himself sanctioned it—but Claus reveals its cost: the early Greeks become mirrors for our psychology rather than thinkers operating within radically different conceptual frameworks. Wolfgang Giegerich’s insistence that “the soul’s life is at bottom logical life” resonates here unexpectedly: Claus demonstrates that the logos of psyche had to be logically constructed through centuries of semantic labor before it could become available as a first principle.

What Makes This Book Irreplaceable Is Its Refusal to Treat “Soul” as a Transhistorical Given

The deepest contribution of Toward the Soul for readers immersed in depth psychology is its demonstration that “soul” is not a natural kind but a cultural and linguistic achievement. Hillman defines soul as “a perspective rather than a substance, a viewpoint toward things rather than a thing itself.” Claus would not disagree with this as a modern psychological move, but his historical work shows that even this flexible, perspectival definition depends on conceptual ground that did not exist before the fifth century BCE and was not consolidated until Plato. The archaic Greek did not have “a perspective toward things” called psyche; the archaic Greek had multiple, often competing terms for cognitive, emotional, and vital functions that were not organized under any single heading. For anyone working within the Jungian or post-Jungian traditions, this is both a humbling and a clarifying realization. It means that the appeal to “psyche” as the foundational word of the discipline carries within it an entire history of consolidation, abstraction, and mythologization. Claus does not ask us to abandon the word, but he makes it impossible to use it naively. For the depth psychologist, this is the gift of the book: it transforms “psyche” from a self-evident starting point into a question—which is, after all, precisely the condition in which genuine psychological inquiry begins.
