Parmenides

Παρμενίδης ὁ Ἐλεάτης

c. 515 BCE – ?Historically documented person

Philosopher of Elea in Magna Graecia (born around 515 BCE), author of a hexameter poem of which some hundred and sixty lines survive. In it a goddess teaches that only "what is" can be thought and said, and that it is unborn, imperishable, one and unmoving; the second part sets out the opinions of mortals. Founder of the Eleatic school, teacher of Zeno and, by tradition, lawgiver of his city, his argument shaped all later philosophy.

In their words

«Meet it is that thou shouldst learn all things, as well the unshaken heart of well-rounded truth, as the opinions of mortals in which is no true belief at all.»

Their central idea

What is (to eon): The poem turns on a single word, the Greek verb *esti*, "is", often without an expressed subject.

Biography

5 min read

The poem of a single path

Parmenides wrote a single poem in hexameters, the verse of Homer and Hesiod, of which some hundred and sixty lines survive thanks to quotations by Sextus Empiricus, Simplicius, Proclus, Plutarch and others. It is the first text of Greek philosophy that argues step by step, and the first to ask what it means to say that something "is". Plato, who called him "venerable and awesome", devoted a dialogue to him and presented the break with his doctrine as "parricide"; Aristotle discussed his theses at the start of the Physics. All later natural philosophy, from Empedocles to the atomists, can be read as a response to his denial of coming-to-be and perishing.

Elea

Elea—Hyele to its founders, Velia to the Romans—was a young colony on the Tyrrhenian coast, south of Posidonia. It had been founded around 540 BCE by Phocaeans fleeing the Persian advance in Ionia, as Herodotus tells. Diogenes Laertius makes Parmenides the son of Pyres, of a noble and wealthy family, and, following Apollodorus, places his prime in the 69th Olympiad (504–501 BCE), which would give a birth around 540. Plato, by contrast, relates in the Parmenides that the philosopher visited Athens at about sixty-five, when Socrates was very young, which would place his birth around 515. Burnet suspected that Apollodorus had made his floruit coincide with the foundation of Elea; many scholars prefer the Platonic chronology, though the dialogue's scene is probably a literary fiction; Burnet, who took it as historical, was among the few who defended it.

Teachers, pupils and laws

The ancients gave him several teachers. Aristotle records that he was said to be a pupil of Xenophanes, the poet-philosopher who criticised Homer's gods and who also lived in the Greek West; Theophrastus linked him with Anaximander. Sotion, more specific, said that a poor but noble Pythagorean, Ameinias son of Diochaitas, led him to the quiet life of study, and that at his death Parmenides built him a hero-shrine. Speusippus, Plato's nephew, stated that he gave his city laws, and Plutarch adds that Elea's magistrates swore every year to abide by them; Strabo credits the city's good government to Parmenides and Zeno, his most famous pupil.

In 1962 the excavations at Velia brought to light a headless herm of the first century CE inscribed "Parmenides, son of Pyres, Ouliades, natural philosopher". Other inscriptions from the same building honour physicians with the title Ouliades, which refers to Apollo Oulios, the healer. The find suggests that, centuries later, a medical school at Elea claimed Parmenides as its forebear. Peter Kingsley has proposed seeing him as an iatromantis, a healer-priest who practised incubation, and reading the poem as the account of a visionary experience; the hypothesis is suggestive but rests on no direct evidence, and most scholars regard it as speculative.

The journey

The poem opens with a journey. A youth is carried in a chariot by wise mares, guided by the daughters of the Sun, who have left the house of Night; the axles shriek in the wheel-naves. They reach the gates of the paths of Night and Day, whose keys are kept by avenging Justice; the maidens persuade her and the gates swing open. On the other side a nameless goddess takes the youth by the right hand and announces that he must learn everything: "the unshaken heart of well-rounded truth" and the opinions of mortals, in which there is no true belief. Sextus Empiricus, who preserves this proem, read it as an allegory of knowledge; Walter Burkert saw in it a descent to the underworld, and others an initiation.

The way of truth

The goddess teaches that there are only two conceivable ways of inquiry: that "it is" and cannot not be, and that "it is not" and must not be. The second is impassable, for what is not can be neither known nor said; "for the same thing is for thinking and for being" (B3). Mortals, however, wander along a third track: "two-headed", without judgement, they believe that being and not-being are the same and not the same. The long fragment 8, which Simplicius copied out in the sixth century because, he says, the book had become rare, deduces the "signs" of what is: it is unborn and imperishable, for it cannot come from what is not; it is whole, single, unmoving and complete; "it neither was nor will be, since it is now, all together, one, continuous"; and it is bounded on every side, like the mass of a well-rounded sphere.

What exactly "what is" is remains disputed. On the traditional interpretation Parmenides denies the plurality and change of the world; G. E. L. Owen read it as a thesis about whatever can be an object of thought; Alexander Mourelatos and Charles Kahn stressed the predicative and veridical sense of the Greek verb; John Palmer has defended a "generous monism", on which Parmenides describes what necessarily is without denying that other things exist.

The way of opinion

Having closed his "trustworthy account", the goddess sets out the "deceptive order" of mortal opinions: a world built from two forms, light or ethereal fire and dense night, of which few lines survive. They speak of celestial rings, of a divinity who steers all things and devised Eros first of the gods, of the moon shining "with borrowed light" and always looking towards the sun's rays, of the formation of the embryo and of thought according to the mixture of the limbs. Parmenides was credited with recognising that the morning and evening stars are one and that the earth is spherical, though the same reports are told of Pythagoras. Why a goddess teaches in detail a cosmology she declares false is one of the poem's riddles.

The legacy of Elea

Zeno, his pupil, defended the doctrine with paradoxes exposing the absurdities of plurality and motion; Melissus of Samos reformulated it in prose. Empedocles, Anaxagoras, Leucippus and Democritus accepted that nothing comes from nothing or is annihilated, and explained change as the mixing and separating of unchanging elements. Plato, in the Sophist, had to "lay hands on father Parmenides" to make sense of not-being as otherness. Nothing is known of his death. His poem, lost as a book, survived in the Neoplatonic commentaries and is today one of the most studied texts of antiquity.

  7. c. 450 BCE · age 65

    Visit to Athens with Zeno

    According to Plato's Parmenides (127a–c), he attends the Great Panathenaea with Zeno, stays in the Ceramicus and converses with a very young Socrates. The meeting is probably a literary fiction; Athenaeus (XI 505f) already doubted it.

    Disputed

  8. c. 370 BCE

    Plato writes the Parmenides and the Sophist

    Plato makes Parmenides the protagonist of a dialogue and, in the Sophist (241d), presents the critique of his thesis on not-being as "parricide".

On Nature (poem) — Parmenides

Written work · c. 480 BCE

On Nature (poem)

Περὶ φύσεως (título convencional)

A didactic poem in dactylic hexameters, divided into a proem and two parts. In the proem (B1) a youth travels by chariot to the gates of Night and Day and is received by a goddess who promises to teach him the truth and the opinions of mortals. The way of truth (B2–B8.49) argues that only "what is" can be thought and said, and deduces that it is unborn, imperishable, one, continuous, unmoving and like a sphere. The way of opinion (B8.50–B19) sets out a cosmology of two principles, light and night, with theories of the stars, the moon, generation and thought. It is the founding text of Western ontology.

Way of Truth (B2–B8.49) — Parmenides

Written work · c. 480 BCE

Way of Truth (B2–B8.49)

Ἀλήθεια (DK 28 B2–B8.49)

The goddess's central teaching. It presents two ways of inquiry—"is" and "is not"—, rules out the second because what is not can be neither thought nor said, and censures the "two-headed" mortals who confuse being and not-being. In B8 it deduces the properties of what is: unborn and imperishable, whole and single, unmoving, without past or future, continuous, bounded and like a well-rounded sphere. It is the first extended deductive argument in Greek philosophy.

Apocryphal quotes or disputed attributions (4)
  • «Nothing comes from nothing (ex nihilo nihil fit).»

    The idea is in B8.7–10, but the Latin formula is not his: it comes from Lucretius (I 150, "nil posse creari de nilo") and scholasticism. It is ascribed to him through textbook summary.

  • «Being is and non-being is not.»

    A textbook formula condensing B2 and B6, but not found as such in the poem. Parmenides says "is" with no expressed subject, and the nominalised "Being" is a later interpretation.

  • «Change is an illusion.»

    A modern paraphrase. The poem says that coming to be, perishing, changing place and colour are "names" mortals have given believing them true (B8.38–41); it does not speak of illusion.

  • «If the one is not, nothing is.»

    The conclusion of Plato's dialogue Parmenides (166c), spoken by the character Parmenides. It is a Platonic construction, not a quotation from the historical philosopher.

Ask

What their work answers

Twelve great human questions and what their texts allow us to answer, with references. We never put words in their mouth.

  • What is the Absolute? Does God exist?

    What is: one, ungenerated, imperishable and complete like a sphere

    An impersonal AbsoluteInferred from their doctrine

    Parmenides does not speak of God in the Way of Truth. What his poem presents as ultimate is “what is”: that which cannot not be, which is neither born nor perishes, which is all at once, one and continuous, and complete on every side like the bulk of a well-rounded sphere. It is held within its limits by Justice and Necessity, divine figures that in the poem function almost as names of logical law. The revelation itself is spoken by a nameless goddess who welcomes the youth in the proem. What the text allows us to affirm is an absolute without personal features, accessible only to thought, from which all genesis, change and plurality are excluded.

    Compare this question with other teachers
  • Who am I? Is there a true self?

    The poem does not treat the self: only being and thinking

    Did not address it

    The surviving fragments of Parmenides contain no doctrine of the self or of the individual soul. The Way of Truth deals with “what is” and its relation to thought — the same is thinking and being, says B3 — but this thinking is not presented as the consciousness of a subject. In the Way of Opinion, B16 explains that the mind of humans depends on the mixture of their limbs at each moment, a physical psychology the goddess herself has labelled the opinion of mortals. The figure of the youth brought before the goddess in the proem is narrative. Readings that see in B3 an identity between consciousness and being belong to the later tradition.

    Compare this question with other teachers
  • Why do we suffer?

    The poem deals with mortals' error, not their pain

    Did not address it

    Parmenides does not ask why we suffer. What his poem diagnoses is something else: the straying of “two-headed” mortals, who know nothing, wander deaf and blind, and take being and not-being as the same and not the same (B6). That error is cognitive, not moral or existential, and the remedy the goddess offers is to judge by reason and not be carried along by the habit of the senses (B7). Neither the Way of Truth nor the remains of the Way of Opinion, devoted to cosmology and physiology, treat human pain as a problem. Attributing a doctrine of suffering to him would be inventing it.

    Compare this question with other teachers
  • What happens after death?

    What is is neither born nor dies; the poem ignores the individual

    Did not address it

    The fragments of Parmenides do not deal with what happens to the person after death. The Way of Truth holds that what is is ungenerated and imperishable, because from what is not nothing can come and into it nothing can go; Justice does not loosen her fetters to let it be born or perish. But that argument concerns being as such, not the individual soul, and applying it to the soul would be an extrapolation. The Way of Opinion, which contains the cosmology, mentions a divinity that governs birth and the union of the sexes, but the surviving remains say nothing of a destiny after death.

    Compare this question with other teachers
  • How is liberation or salvation attained?

    A journey from night to light to learn well-rounded truth

    Through direct knowledgeInferred from their doctrine

    Parmenides' proem narrates a journey: mares carry the youth, “the man who knows”, along the road of the goddess; the daughters of the Sun leave the halls of Night and open for him the gates guarded by Justice. There the goddess promises to teach him everything: both the unshaken heart of well-rounded truth and the opinions of mortals, in which there is no true belief. The rest of the poem is that teaching, and its condition is to judge by reason and not by the unseeing eye or the echoing ear. If one can speak of liberation in Parmenides, it is that of thought leaving the path of mortals.

    Compare this question with other teachers
  • Is a teacher necessary?

    A goddess teaches, but asks that her proof be judged by reason

    Helpful but not indispensableInferred from their doctrine

    Parmenides' poem takes the form of teaching: a nameless goddess welcomes the youth, takes his right hand and promises to teach him the truth and the opinions of mortals. It might seem a revelation accepted on authority. Yet the goddess asks for no faith: she urges him not to be carried by the habit of the senses and to judge by reason the much-contested refutation she sets before him (B7). The divine guide opens the way, but assent depends on the disciple's reasoning. The fragments say nothing of human teachers; tradition makes Parmenides a pupil of Xenophanes and of the Pythagorean Ameinias, and teacher of Zeno of Elea.

    Compare this question with other teachers
  • Is the world real?

    Only what is is; the world of mortals is name and opinion

    Appearance over the one realityStated explicitly

    The Way of Truth proves that what is can neither come to be nor perish, nor move, nor be divided, because that would mean admitting what is not. It follows that the world the senses perceive — birth, death, change of place, alteration of colour — consists of names mortals have laid down trusting them to be true. Yet the goddess does not simply dismiss that world: in the second part of the poem she sets out a complete cosmology, based on light and night, so that no mortal may outstrip him in knowledge, although she warns that its arrangement is deceptive. The world has the consistency of appearance; only what is is fully real.

    Compare this question with other teachers
  • What is love?

    Eros appears only in the cosmogony, as the first of the gods

    Did not address it

    Parmenides does not treat love as a human experience or as a path. In the Way of Opinion, devoted to the cosmology of mortals, a divinity who governs all things drives the union of female and male (B12), and of her it is said that she devised Eros, first of all the gods (B13), a line Plato quotes in the Symposium. It is a cosmogonic force explaining generation, not a doctrine of love as a bond between persons or as longing for the divine. Moreover, the goddess presents that whole section of the poem as the opinion of mortals. On love in an ethical or mystical sense, Parmenides is silent.

    Compare this question with other teachers
  • Are we free, or is everything determined?

    Necessity binds being, but the poem says nothing of human action

    Did not address it

    In Parmenides' poem Necessity and Justice appear often, but not as forces governing human life. In the Way of Truth mighty Necessity holds what is in the bonds of the limit, and Justice does not loosen her fetters to let it come to be or perish: they are figures of the immutability of being. In the cosmology, Necessity binds the heaven to hold the limits of the stars (B10). None of the fragments asks whether humans choose their acts or whether everything is determined. Ancient tradition made Parmenides lawgiver of Elea, but his laws do not survive. On this question he is silent.

    Compare this question with other teachers
  • Why meditate or pray?

    The proem's journey is no method of prayer or meditation

    Did not address it

    The fragments of Parmenides contain no teachings on prayer or meditative practices. The proem narrates a chariot journey to a goddess and is full of religious imagery — the daughters of the Sun, Justice holding the keys, the gates of the paths of Night and Day —, but its function in the poem is to introduce a teaching that must be judged by reason. A recent line of interpretation, represented by Peter Kingsley, has linked Parmenides with Apollo's healer-priests at Elea and with incubation practices; it rests on inscriptions found at Velia, not on the poem. Attributing a doctrine of prayer to him would go beyond the texts.

    Compare this question with other teachers
  • Can reason know the ultimate?

    A goddess reveals the truth, but demands it be judged by reason alone

    Faith and reason help each otherInferred from their doctrine

    Parmenides is at once the thinker of revelation and the founder of deductive argument. His poem puts the truth in the mouth of a goddess, reached by a journey far from the paths of men; but what the goddess teaches is rigorous reasoning, and her watchword is not to be carried by the habit of the senses but to judge by reason the refutation she proposes. For Parmenides thought does reach the ultimate: thinking and being are the same, and what is not cannot be thought or said. Divine revelation and reason do not compete: the first provides the frame, the second the proof; the senses are relegated to opinion.

    Compare this question with other teachers
  • Withdraw from the world or transform it?

    The poem does not treat social life; tradition made him a lawgiver

    Did not address it

    The fragments of Parmenides' poem contain no reflection on how to live among humans, whether to withdraw or act in the city. The proem's journey takes the youth far from the paths of men, but that distance is one of knowledge, not a programme of life. Reports of his public life come from other sources: Speusippus, according to Diogenes Laertius, said he gave laws to his fellow citizens of Elea, and Plutarch adds that magistrates swore each year to observe them. If so, Parmenides would have been an active citizen; but his laws do not survive and cannot be connected with his doctrine. On this question his work is silent.

Ameinias' shrine

Parmenides, Sotion relates, heard Xenophanes but did not follow him. The one who led him to the quiet life of study was Ameinias son of Diochaitas, a poor but noble Pythagorean. Parmenides, of an illustrious and wealthy family, became his companion and, when Ameinias died, built him a *heroon*, a small shrine of the kind dedicated to heroes and founders. The scene has a concrete air—the father's name, the poverty, the monument—that led Burnet to write that it "does not read like an invention", since Alexandrian scholars had information about southern Italy now lost; it also fits the relationship ascribed to Parmenides with the Pythagorean circles of southern Italy.

Origin of the story: Diogenes Laertius IX 21, quoting Sotion of Alexandria (2nd century BCE). There is no other source. Burnet (Early Greek Philosophy, § 84) considers it plausible.

The magistrates' oath

Speusippus, Plato's nephew and successor at the Academy, wrote that Parmenides had given laws to his fellow citizens. Plutarch, four centuries later, adds a detail: Parmenides ordered his city with such excellent laws that the magistrates swore every year, on taking office, to abide by the laws of Parmenides. Strabo, for his part, credits Parmenides and Zeno with the good government of Elea, which held out against the Lucanians and the Posidonians despite its small territory. The report, transmitted by a fourth-century BCE Academic, is one of the oldest about his life and belies the image of a metaphysician withdrawn from the world.

Origin of the story: Speusippus in Diogenes Laertius IX 23; Plutarch, Against Colotes 1126a–b; Strabo VI 1.1. The three sources are independent of one another, though none is contemporary.

The meeting with the young Socrates

Plato relates that Parmenides and Zeno came to Athens for the Great Panathenaea. Parmenides was already very old, his hair completely white, noble in appearance and about sixty-five; Zeno, tall and graceful, was about forty. They stayed at Pythodorus' house in the Ceramicus, and there Socrates, then very young, came with others to hear Zeno's book read. The conversation that follows, in which Parmenides criticises the young Socrates' theory of Forms, fills the dialogue Parmenides. In the Theaetetus Socrates recalls that meeting: Parmenides seemed to him "venerable and awesome", with a depth altogether noble. Already Athenaeus, in the second century CE, objected that the chronology made it impossible, and many scholars regard it as literary fiction; Burnet and Eduard Meyer, by contrast, considered it historical, since Plato mentions it in three different dialogues. In any case, the age Plato gives him is the basis of modern chronology.

Origin of the story: Plato, Parmenides 127a–c; Theaetetus 183e; Sophist 217c. Athenaeus, Deipnosophists XI 505f, considers it anachronistic. It is a literary testimony without independent confirmation.

"Parmenides, son of Pyres, Ouliades, natural philosopher"

In 1962, in the excavations at Velia—ancient Elea, on the Cilento coast—archaeologists found a group of marble herms of imperial date. One, headless, was inscribed: "Parmenides, son of Pyres, Ouliades, natural philosopher". Others honoured physicians named Oulis, with the same title of *Ouliades* and the designation *iatros* or *pholarchos*. The find, published in 1962 in the journal Apollo and later studied by Giovanni Pugliese Carratelli, showed that centuries after his death a corporation of physicians, tied to the cult of Apollo Oulios the healer, revered Parmenides as its ancestor. A male head of the first century CE found at the same site has since been identified with him.

Origin of the story: Packard Humanities Institute, inscription no. 301222 (Apollo 2, 1962, 125–136; SEG 38.1020). Reading "Ouliades" as the title of a medical school is the most widespread interpretation; Peter Kingsley developed it into his hypothesis of Parmenides the healer.

The evening star and the morning star

Favorinus, a second-century scholar, credited Parmenides with discovering that Hesperus, the evening star, and Phosphorus, the morning star, are the same body; Theophrastus, according to Diogenes Laertius, regarded him as the first to state that the earth is spherical and lies at the centre. The same firsts were also ascribed to Pythagoras, and the poet Callimachus cast doubt on some of these reports. What the fragments do attest is a precise astronomical observation: the moon shines "with borrowed light" and looks "always towards the beams of the sun" (B14–B15), the first surviving statement that moonlight is reflected sunlight.

Origin of the story: Diogenes Laertius IX 21 and 23 (Theophrastus, Favorinus); VIII 14 and 48 ascribe the same to Pythagoras. Fragments B14 and B15 are transmitted by Plutarch.

Simplicius and the rarity of the book

Around the year 530, a thousand years after Parmenides, the Neoplatonist philosopher Simplicius was commenting on Aristotle's Physics. On reaching the discussion of the Eleatics he decided to copy out at length Parmenides' lines on what is, and explained why: he did so "because of the rarity of the book". Thanks to that decision we have almost entire fragment 8, sixty-one lines containing the core of the Parmenidean argument. Simplicius was one of the last philosophers of the Athenian school, closed by Justinian in 529, and probably worked from one of the last complete copies of the poem.

Origin of the story: Simplicius, Commentary on Aristotle's Physics 144.25–28 (ed. Diels, 1882). The commentator himself states his motive.

Teachings

Teachings

The notions that structure their thought, explained in context.

What is (to eon)lo-que-es
The poem turns on a single word, the Greek verb *esti*, "is", often without an expressed subject. Parmenides makes it the object of inquiry: what is (*to eon*) cannot have come to be, for it would have to come from what is not, which cannot be thought; for the same reason it cannot perish, grow, have parts more or less full, or move. Nor does it have past or future: "it is now, all together, one, continuous" (B8.5–6). And it is bounded, for Necessity holds it in her bonds and the unlimited would be incomplete. Tradition has understood it as "Being" with a capital letter and as the first formulation of monism. But the sense of the verb is disputed: it can be existential (that something exists), predicative (that something is such-and-such) or veridical (that something is the case), and each reading changes the thesis.

The core of the way of truth (B2, B6, B8).

The two ways of inquirylas-dos-vias
The goddess presents inquiry as a choice between roads (*hodoi*). In B2 there are two: "that it is and cannot not be", the path of Persuasion attending on Truth, and "that it is not and necessarily is not", an unsearchable track, for what is not cannot be known or said. In B6 a third appears, that of "two-headed" mortals who wander without judgement, believing being and not-being the same and not the same, and for whom the path of all things turns back on itself. The road metaphor structures the whole poem: the proem's journey, the crossroads, the "signs" marking the true way (B8.2). Alexander Mourelatos studied this imagery as the key to the work, and many interpreters see in the third way a critique of Heraclitus.

Fragments B2, B6, B7 and B8.1–2.

Thinking and beingpensar-y-ser
"For the same thing is for thinking and for being" (B3) is probably the most quoted and debated line of Parmenides. At the very least it holds that only what is can be thought: thought cannot take nothing as its object. B8.34–36 develops it: thinking and that for the sake of which there is thought are the same, for you will not find thinking without what is, in which it is expressed. Plotinus read in B3 the identity of Intellect and being; German idealism and Heidegger made it the origin of Western metaphysics. Philologists point out that the Greek syntax allows a more modest reading—"the same thing can be thought and can be"—which does not identify thought and reality but establishes that only the real is thinkable.

Truth (aletheia) and opinion (doxa)verdad-y-opinion
The goddess promises to teach two things: the unshaken heart of truth and the opinions of mortals, "in which there is no true belief" (B1.28–30). The second part of the poem builds a cosmos from two forms, light and night, which mortals "decided to name" when they should have named only one (B8.53–54). The poem then adds an enigmatic line: thus you will learn how the things that seem had to be acceptably, pervading all (B1.31–32). For some interpreters the doxa is a rival doctrine Parmenides sets out in order to refute it; for others, the best possible account of the sensible world, false in the strict sense but superior to the rest; for others again, a legitimate part of his thought. The distinction between the intelligible and the sensible that Plato would develop has its first sketch here.

The well-rounded sphereesfera
At the end of the way of truth Parmenides compares what is to "the mass of a well-rounded sphere, equally balanced from the centre in every direction" (B8.43–44). The image expresses perfection and homogeneity: nothing is more here and less there, nothing is lacking, its limits are equal on every side. Already in antiquity it was debated whether the sphere was literal—a finite, spherical physical universe—or a comparison, as the particle *enalinkion*, "like", indicates. Melissus, his follower, rejected the limit and declared what is infinite. Empedocles took up the image in his Sphairos, the state of perfect unity under Love, and the Platonic and Neoplatonic tradition turned it into a symbol of the divine.

The journey of the proemel-viaje-del-proemio
The poem does not begin with an argument but with a first-person narrative: the youth's chariot journey to the gates of Night and Day and his reception by a goddess. The imagery comes from epic and religious poetry: the Heliades, the bronze gates, Justice keeping the keys, the right hand clasped. Sextus Empiricus read it as allegory: the horses are the soul's impulses, the maidens the senses, the goddess reason. Hermann Fränkel and Walter Burkert linked the journey to the underworld descents of Orphic and shamanic poetry; Peter Kingsley interprets it as the account of an incubation in which the sage receives revelations from the gods. Whatever its origin, the proem presents truth as something received after a journey off the beaten track of men, not as the author's opinion.

  • Influenced

    Aristotle

    He discusses the Eleatic thesis at the start of the Physics (I 2–3) and in the Metaphysics (A 5), and explains the pluralists as a response to it.
