Presocratic Philosophy

presocratic monism · presocratic fragments

Presocratic philosophy occupies a distinctive and contested position within the depth-psychology corpus. Scholars engage the Presocratics not as antiquarian curiosity but as the foundational stratum of Western psychological and cosmological thought — the moment when Greek thinkers first articulated systematic accounts of soul, cosmos, and their interpenetration. Sullivan’s meticulous philological survey traces how figures from Anaximander to Democritus developed concepts of psyche, noos, and justice that anticipate, and in several cases directly enable, later Platonic and Aristotelian formulations. Seaford advances a more provocative materialist thesis: that Presocratic monism — the drive to reduce cosmic multiplicity to a single abstract principle — is structurally homologous with, and likely historically conditioned by, the advent of coinage and monetary abstraction in archaic Greece. Claus probes the doxographical record for the earliest semantic uses of psyche among the Milesians, Heracliteans, and atomists, insisting that material soul-doctrines are indispensable antecedents to the Socratic revolution. Aristotle’s De Anima provides the canonical critical framework against which all Presocratic psychology is measured, while Havelock situates Presocratic syntax and abstraction within the broader transition from oral to literate cognition. The central tension across these voices is whether Presocratic thought is best understood as protoscientific cosmology, as theological displacement, or as unconscious projection of emerging social institutions onto the structure of nature.

there is indeed, if our argument is correct, an explanation of the sixth-century adoption of monism – in the monetisation that Stokes fails to see at the heart of the economic change

Seaford argues that the Presocratic adoption of material monism is causally explained by archaic monetisation, not by abstract philosophical deduction or mere cosmological observation.

The presocratics, then, tend to project the mind onto the macrocosm, and it seems that Philolaus projects (mental) limiting of the unlimited

Seaford identifies a structural pattern in Presocratic thought whereby mental operations — limiting, unifying, measuring — are projected cosmologically, with money providing the unconscious template.

Parmenides, like the presocratics generally, is concerned with ontology: uppermost in his sublimation of money is its being rather than its value.

Seaford contends that Parmenidean ontology represents a sublimation of monetary abstraction, where the impersonal unity of exchange-value is transposed into the metaphysical unity of Being.

it can be suggested that Parmenides’ being is a notion invented with a view to overcoming the difficulty faced by material monism: Being is the unifi

Seaford argues that Parmenidean abstract monism arose as a logical solution to the contradictions inherent in earlier Milesian material monism, itself shaped by monetary abstraction.

The Presocratics are more concerned about the role of human beings in the cosmos and the nature of that cosmos than about their role in society.

Sullivan distinguishes Presocratic philosophy from later Socratic ethics by its emphasis on cosmological rather than social questions, marking a transitional phase in Greek psychological thought.

As in other Presocratics, we encounter here a microcosm/macrocosm view of the universe. The microcosm acts as a pattern for a principle assumed to be operative as well in the macrocosm.

Sullivan identifies the microcosm/macrocosm homology as a defining structural feature of Presocratic thought, with justice operating simultaneously in human society and in cosmic order.

Heraclitus assumes that justice is ever operative, keeping the components of the universe perfectly poised. Parmenides rejects the notion of justice as a balance of opposites.

Sullivan maps the divergent positions on cosmic justice among the Presocratics, showing how each thinker’s cosmology entails a distinct theory of psychic and natural order.

by using prose, they may have wished to show how and to what degree human beings could come to understand that very divinity by using innate instead of inspired abilities.

Sullivan interprets the Presocratics’ choice of prose as a deliberate epistemological statement, privileging rational human cognition over inspired poetic authority.

the most glaring case of unwarranted assimilation is the treatment of the great atomist thinker Democritus of Abdera, who is effectively classed by Aristotle as holding the view that the soul is made of fire.

Aristotle’s critical engagement with Presocratic soul-theories is shown to involve systematic misassimilation, indicating the difficulty of recovering authentic Presocratic psychology from later doxographical tradition.

in the whole of surviving presocratic philosophy the idea of a cosmological or physical law (i.e. something similar to our scientific law) does not to my knowledge occur.

Seaford distinguishes Presocratic cosmological regularity from scientific law, arguing that the ordering principle in Presocratic thought operates more like internalised convention than explicit legislation.

the doxographical materials collected in the A fragments are all but useless for semantic purposes; for the most part they are concerned only with the material composition of soul and with general theories of cognition and animation.

Claus raises a methodological warning about doxographical sources for Presocratic psychology, arguing that they obscure semantic nuance in favour of material and causal generalisations.

The universe (‘all things’) is guided by a divine principle called the ‘Infinite’ (Apeiron). The universe is made up of opposites in conflict. These opposites are regulated by Justice that imposes balance between each opposing pair.

Sullivan’s reference appendix provides a concise doctrinal summary of the Milesian Presocratics, foregrounding the Apeiron and cosmic justice as central organising concepts.

for Empedocles the occult self that survives physical death, acquires knowledge through metempsychosis, and eventually seeks to withdraw from the cycle of birth and death is not the psyche common to all men but something described by paraphrase or as a theos or daimon.

Claus argues that the eschatological self in Empedocles is not coextensive with psyche as ordinarily conceived, complicating any straightforward alignment of Presocratic cosmology with soul-doctrine.

money provides a central object of thought and action, a single-mindedness… money reduces the need for reciprocal personal relations and so tends to delimit the individual unitary mind from all else

Seaford develops the structural parallel between money, mind, and cosmos that underlies his broader argument about the monetary preconditions of Presocratic monism.

Xenoph. B 23, 24, 26; Heracl. B 10, 30, 32, 41, 50, 57, 89; Parm. B 2, 4, 8 passim… the language used by his colleagues is equally committed to an assertion of identity, continuity and unity.

Havelock identifies a pervasive Presocratic linguistic commitment to identity and unity across the fragmentary texts, connecting this to the broader transition from Homeric to abstract philosophical discourse.

The Pythagoreans also maintained the idea of palingenesia, reincarnation. Pythagoras himself was supposed to have remembered many of his reincarnations.

Edinger translates Pythagorean metempsychosis into a depth-psychological idiom, reading reincarnation as symbolic experience of the collective unconscious rather than literal doctrine.
