Hippocrates appears in the depth-psychology corpus not as a subject of sustained clinical analysis but as a foundational authority whose name anchors recurring debates about the mind-body relationship, the humoral theory of psychic disturbance, the holistic method in medicine, and the medical analogy for philosophical therapy. Plato’s Phaedrus invokes him as the Asclepiad who insists that nature can be understood only as a whole—a passage that echoes through later discussions of psychological totality. The Tzeferakos essay credits him with consolidating Pythagorean and Empedoclean humoral cosmology into a systematic psychiatric framework, noting that the Hippocratic Oath itself may be of Pythagorean provenance. Hillman reads him as the earliest clinical witness to the somatic reality of nightmare phenomena, citing Hippocratic texts on feverish dream-terrors as progenitors of the depth-psychological understanding of the night-world. Galen’s voluminous commentaries on Hippocratic texts—transmitted through Long and Sedley’s Hellenistic Philosophers—carry the Hippocratic legacy into Stoic debates on passion, the commanding faculty, and the seat of the soul. Kandel positions Hippocrates as the first to reject superstition and locate mental processes in the brain, making him a secular ancestor of neuroscientific psychology. What unites these dispersed invocations is the persistent authority of Hippocrates as the founding figure of a naturalistic, observation-based account of mind and illness.
Hippocrates the Asclepiad says that the nature even of the body can only be understood as a whole… we ought not to be content with the name of Hippocrates, but to examine and see whether his argument agrees with his conception of nature.
Plato’s Socrates invokes Hippocratic holism as the methodological standard against which both medicine and rhetoric must be measured, establishing the ‘whole nature’ principle as the Hippocratic signature contribution.

Hippocrates was the first physician to cast superstition aside, basing his thinking on clinical observations and arguing that all mental processes emanate from the brain.
Kandel positions Hippocrates as the inaugural figure of a brain-based, empirically grounded psychology, placing him in direct contrast to Plato’s immaterialist soul-theory.

The work of Pythagoras and Empedocles, originator of the cosmogenic theory of the four classical elements (fire, earth, air, and water), formed the basis for the humoral theory of Hippocrates.
Tzeferakos traces the intellectual genealogy of Hippocratic psychiatry to Pythagorean harmony theory and Empedoclean elemental cosmology, situating Hippocrates as a synthesizer rather than originator.

Let us compare, for example, Hippocrates: ‘The evil in these fevers and cramps (contortions) from dreams,’ to which Galen adds: ‘We also notice in dreadful illnesses oppressions, fears, and cramps stemming from dreams.’
Hillman marshals Hippocratic and Galenic clinical testimony on nightmare-induced somatic crises to establish an ancient medical grounding for depth psychology’s account of the night-world’s pathological power.

Galen, On Hippocrates, and Plato’s doctrines 3.1.25 (SVF 2.886, part) [Chrysippus:] ‘I think that people in general come to the view that our commanding-faculty is in the heart through their awareness, as it were, of the passions that affect the mind happening to them in the chest.’
Galen’s commentary on Hippocrates and Plato serves as the textual vehicle through which Stoic debates about the seat of the commanding faculty and the somatic location of passion are conducted.

The author of Vet. Med., and Aristotle, insist that this second person’s knowledge would still fall short of techne: ‘He must say what sort of pain it is and why it arises and what part of the human being is badly affected.’
Nussbaum draws on the Hippocratic text Vet. Med. to define the epistemological standard of techne—causal explanation linked to prediction and control—that governs both medical and practical-rational inquiry.

If, for example, you had thought of going to Hippocrates of Cos, the Asclepiad, and were about to give him your money… tell me, what is he that you give him money? how would you have answered? I should say, he replied, that I gave money to him as a physician.
Plato uses Hippocrates of Cos as the paradigm case of a named expert whose professional identity and the value of his art are subjected to Socratic scrutiny about what a teacher actually produces in a pupil.

Rank references Roscher’s scholarship on the Hippocratic treatise On the Sevens, linking Hippocratic numerology to Pythagorean cosmology and cross-cultural mythic symbolism.
