Epinomis (The Philosopher)

Author: Plato (disputed — a dubium; ancient testimony names Philip of Opus) · Year: c. 4th c. BCE (trans. Richard D. McKirahan, Jr., Hackett 1997) · Type: dialogue

An explicit appendix to the Laws — the same trio (Athenian Visitor, Clinias, Megillus) reconvene to settle the one question the Laws left open: what study makes the rulers of Magnesia wise? The surprising answer is that wisdom is constituted by the science of number — a gift of Heaven (Uranus) taught to mortals through the visible celestial cycles — culminating in astronomy understood as theology: the stars are visible gods, and the true astronomer is therefore the wisest and most pious of human beings. The author opens with a serial survey eliminating every recognized art and craft as a source of wisdom, argues that number is the condition of all rational account, re-deploys the Laws X priority-of-soul argument to prove the heavenly bodies are ensouled intelligences, sketches a cosmology of five bodies (fire, water, air, earth, ether) with daemonic intermediaries, and ends by prescribing a graded mathematical curriculum — converging on a "single bond" linking all the sciences — as the supreme study for the Nocturnal Council. Cooper's introductory note records the scholarly consensus that Plato is not the author and reports the ancient attribution to Philip of Opus, transcriber of the Laws; the work is read as one of the first "Platonisms," carrying Plato's spirit "while giving selective and distorting emphases." The single most-cited marker of its non-Platonic character is what is absent: the Forms do no work, mathematical astronomy and the visible cosmic gods standing in their place.

Core Arguments

  1. Claim: None of the recognized arts or sciences makes a human being wise; wisdom "takes to its heels" wherever expertise is achieved. Because: a serial survey eliminates each candidate — the food arts (farming, milling), the crafts (building, weaving, bronze-working), hunting, prophecy (the prophet "only knows what he says; he does not understand if it is true," 975c), the imitative/Muse arts, and the defensive arts (military strategy "granted through courage more than wisdom," 976a; medicine, seamanship, forensic rhetoric "stray wide of the truth about what is genuinely just," 976b). None confers virtue; all "lack measure, are carried along by opinion, and proceed by guesswork." Against: an opponent says the survey rigs the criterion — by demanding a science that by itself makes one wise, good, and happy, it disqualifies every practical art a priori, dismissing them by stipulation rather than refutation. Location: 974d–976c.

  2. Claim: The wisdom-making science is the science of number — the one whose disappearance would render the mortal race "the most unintelligent and senseless of living things." Because: a counterfactual subtraction test — remove number and every other art collapses with it ("They are all completely eliminated when we take away the science of number," 977b); without number an animal "could never give an account," and "no one deprived of the ability to give a true account can ever become wise" (977c). Number is thus the condition of rational account itself, hence of "the greatest part of all virtue." Against: a critic grants that number is necessary for reckoning but denies it is sufficient for wisdom about justice and the good — the slide from "condition of reason" to "the science that makes us wise and good and happy" is the disputed step the author himself concedes "would require a still longer account" (977b). Location: 976d–977c, 991a.

  3. Claim: Number is a divine gift from Heaven (Uranus), and the heavens themselves teach mortals to count through their visible cycles. Because: it is "God himself… and not some good fortune" who gives the gift (977a) — the god Uranus/Cosmos, "the god whom above all others it is most just to pray to." The teaching is concrete: day and night, then the moon's waxing and waning, "never stops teaching humans one and two" (978d) until even the slowest learns to count, while the year coordinates "number in relation to number" (979a). Against: a sceptic reads this as pious cosmology dressed as epistemology — celestial regularity supplies the occasion for forming number-concepts, not their divine origin. Location: 977a–979b.

  4. Claim: Soul is prior to body, and the orderly motion of the heavens is decisive evidence that the stars are ensouled, intelligent gods. Because: continuing Laws X — "as a whole, soul is older than any body" (980e); soul is invisible, intelligent, self-moving and ruling, while body is "suited for being fashioned, for becoming, and being seen" (981b). Uniform celestial motion is the mark of mind: "if something has an orderly path in the heavens we should treat that as powerful evidence of its intelligence" (982). Against: the crowd's view, explicitly targeted — that uniformity proves lack of soul, and that change and variability are the signs of life (982c). The author inverts the popular inference; a critic calls the inversion question-begging. Location: 980c–984.

  5. Claim: The cosmos is populated by five kinds of living things built from five bodies — fire, water, air, earth, and ether — with three intermediate, daemonic kinds filling the gap between the fiery visible gods (stars) and earthy mortals. Because: living things are soul-body composites; "they are fire, water, air, earth, and ether" (981c); after fire (stars) come ether-beings, then air-beings, then water-beings, "beginning from the visible gods and ending up with us humans" (985b). The air-made daimons, in "the third, middle, position," are "responsible for mediation between gods and humans" (984e), invisible and of "wonderful intelligence." Against: the demonology is offered under "plausible opinion" (984b) rather than proof; ether as a fifth body and the graded daemonic ranks have a notably non-Platonic (proto-Aristotelian / proto-Hellenistic) flavor — fuel for the authenticity dispute. Location: 981c, 984b–985c.

  6. Claim: The highest wisdom is astronomy, and the true astronomer is the wisest and most pious man — astronomy is theology. Because: "I say its name is astronomy" (990a) — not Hesiod-style observation of risings and settings, but knowledge of the eight ordered circuits. Reverence toward the gods is "the most important part of virtue for mortals" (989b), and impiety is redefined: the genuinely evil man is the one who, seeing the visible cosmic gods, fails "to bring them from their dishonored state into a place of honor" (986a). The atheist is the bad astronomer; the real astronomer, knowing the cosmic order, is the genuinely pious one. Against: this inverts the ordinary suspicion that astronomers and naturalists are impious (the charge against Anaxagoras); a critic notes that it legislates a specific astral religion ("we must be bold and enact this into law," 986c), treating a cosmological hypothesis as required cult. Location: 985c–987, 989b–990b.

  7. Claim: The mathematical sciences form a graded curriculum culminating in a unity-vision, and this is the supreme study to be enacted into law for the Nocturnal Council. Because: arithmetic, geometry, stereometry (solid numbers), and harmonics (the means, 991a–b) are preliminaries; the right method reveals that "every diagram and complex system of numbers, and every structure of harmony" and the star-revolutions form "a single thing" — "a single natural bond that links them all" (991e), grasped by "fixing his eye on unity." A dialectical touchstone — "fit the individual to the species by asking questions and refuting errors" (991c) — supplements the mathematics. The payoff is civic: "the highest offices must be bestowed upon those individuals who have mastered these studies" (992d), and "we are all bound… to urge the Nocturnal Council to pursue it" (992e). Against: the unity-vision is asserted ("it will be revealed") rather than demonstrated; the leap from a mathematical "single bond" to political authority over Magnesia is the move a Laws-faithful reader finds least argued. Location: 990c–992e.

Key Findings

  • Wisdom is relocated from the intelligible Forms to the visible heavens. Where the Republic and Timaeus ground supreme wisdom in the intelligible Forms and the Good, the Epinomis makes the objects of wisdom number and the star-system — a substitution that is the standard interpretive datum for the work's non-Platonic authorship.
  • The Laws' deferral is reversed. The Laws left the rulers' curriculum to the established Nocturnal Council itself; the Epinomis "goes back on" that decision and supplies the curriculum — the reversal is itself, in Cooper's note, evidence of a different hand (see statesmanship).
  • The priority-of-soul argument is bent to a new conclusion. The Laws X premise that soul is older than body (re-cited here at 980c via 891e, 896a) is re-deployed to prove astral intelligence — an inferential use the original argument does not make (see priority-of-soul).
  • A fifth body enters the cosmology. Ether is added to the four elements (981c), diverging from the Timaeus's four-element scheme — a proto-Aristotelian note, paired with a graded daemonology absent from the genuine dialogues.
  • Astronomy is moralized into the test of piety. Atheism is reframed as bad astronomy and reverence for the visible gods is legislated; the naturalist, ordinarily suspected of impiety, becomes the model of virtue.

Concepts Developed

  • Number as the condition of reason / divine gift — the load-bearing thesis: not arithmetic-as-skill but number as that without which no rational account is possible (977b–c), given by Heaven and taught through the visible cycles (978–979), and "the cause of all good things" (977d). The dialogue's distinctive contribution.
  • Astronomy-as-theology / the visible cosmic gods — the redefinition of astronomy as the supreme wisdom because it is knowledge of the divine cosmic order; the stars are "the first gods, those that are visible" (984d), and the genuine astronomer is the truly pious man (990a). Atheism is recast as bad astronomy.
  • The five-bodies + ether + daemonic-intermediaries scheme — a cosmological-ontological ranking: fire/water/air/earth/ether (981c) mapped onto five orders of living beings, with air-daimons mediating between gods and humans (984e–985b). Original in adding ether as a fifth body and in populating the cosmos with graded daemonic life.

Concepts Referenced

  • priority-of-soul — carried over from Laws X (soul older than body) as an established premise (980e–981, 983b), not freshly argued; here it grounds astral intelligence.
  • statesmanship — the Nocturnal Council (from Laws XII) is named only at the close (992e) as the body that must pursue this wisdom; the Epinomis supplies its curriculum.
  • theory-of-forms — invoked here only by its absence: the eidē do no work, mathematical astronomy and the visible gods standing in their place.
  • form-of-the-good — likewise displaced: the role the Form of the Good plays in the Republic is here occupied by number / the cosmic order ("number causes all good things," 977d) — a mathematized substitute, not the Good itself.
  • collection-and-division — a faint echo: "fit the individual to the species by asking questions and refuting errors" as "the first and finest touchstone" (991c), referenced but not developed.
  • plato-timaeus — shared cosmic theology and number-structured cosmos, but presupposed rather than constructed, and diverging on the elements (four vs. five).

Key Passages

"the one that has given the gift of number would have this effect" (976e) — number as the wisdom-making science. "no one deprived of the ability to give a true account can ever become wise" (977c) — number as the condition of rational account. "number causes all good things" (977d) — number occupying the place of the Good. "It is God himself, I believe… that saves us by making us this gift" (977a); "Uranus… the god whom above all others it is most just to pray to" (977a) — the divine gift / astral theology. "he never stops teaching humans one and two" (978d) — the heavens teach counting. "as a whole, soul is older than any body" (980e); "if something has an orderly path in the heavens… evidence of its intelligence" (982) — priority of soul, astral intelligence. "they are fire, water, air, earth, and ether" (981c); "next in order beneath them are daimons" (984e) — the five bodies and daemonic intermediaries. "the first gods, those that are visible… these are the stars" (984d); "I say its name is astronomy"; "the true astronomer must be the wisest person" (990a) — astronomy-as-theology. "reverence towards the gods" is "the most important part of virtue for mortals" (989b); "we must be bold and enact this into law" (986c) — piety legislated. "a single natural bond that links them all" (991e); "the highest offices must be bestowed upon those individuals who have mastered these studies" (992d); "we are all bound… to urge the Nocturnal Council to pursue it" (992e) — the unity-vision and its civic payoff.

What's Not Obvious

  • The Forms are simply absent — and something is wheeled in to replace them. The intelligible eidē that anchor wisdom in the Republic and Timaeus do no work in the Epinomis; their place is taken by mathematical astronomy and the visible cosmic gods, with the Good displaced by number ("number causes all good things," 977d). This is not a silence to be filled in by the reader but a positive substitution, and it is the most-cited single reason scholars judge the work non-Platonic — wisdom here looks up at the heavens, not through the visible toward the intelligible.
  • The dialogue quietly overturns a decision the Laws deliberately made. Laws XII left the rulers' curriculum to the Nocturnal Council to work out for itself; the Epinomis reverses that deferral and hands the Council a finished answer — astronomy as the supreme study. The reversal is easy to miss because the text presents itself as a faithful continuation, yet it is exactly the kind of discrepancy that marks a different author writing under Plato's name (see Laws and statesmanship).
  • Atheism is redefined as bad astronomy, so the naturalist becomes the most pious man. The ordinary Greek suspicion — that those who study the heavens are impious (the charge against Anaxagoras) — is inverted: the genuinely evil man is the one who sees the cosmic gods and leaves them "dishonored" (986a), while the true astronomer is "the wisest" and most reverent (990a). The author then legislates this astral religion — "we must be bold and enact this into law" (986c) — converting a cosmological hypothesis into required cult, a move with no parallel in the genuine dialogues.

Critique / Limitations

Disputed authorship is load-bearing. Cooper's introductory note records the scholarly consensus that Plato is not the author and reports the ancient attribution to Philip of Opus, the transcriber of the Laws; the work is treated as one of the first "Platonisms," carrying Plato's spirit "while giving selective and distorting emphases." Derived pages therefore run at low confidence and the source is weak developmental evidence about Plato's own thought; attributions throughout should be hedged ("the author of the Epinomis / Philip of Opus").

Non-Platonic doctrinal markers. Two features are routinely cited against authenticity and should not be read as Platonic doctrine: (1) the absence of the Forms, with mathematical astronomy and the visible gods substituted for the intelligible eidē and the Good; and (2) ether as a fifth body (981c) plus the graded daemonology — divergences from the Timaeus's four elements that carry a proto-Aristotelian / Hellenistic flavor.

Argumentative gaps. The survey of the arts (974d–976c) eliminates every practical art by stipulating in advance a science that "by itself" makes one wise; the inference from "number is the condition of reason" to "number is the science that makes us good and happy" is conceded to need "a still longer account" (977b); and the leap from a mathematical "single bond" (991e) to political authority over Magnesia (992d) is asserted rather than demonstrated.

Connections

  • extends plato-laws — presents itself as the explicit appendix completing the Laws, answering what study makes the rulers wise; but note it reverses the Laws' decision to leave curriculum-setting to the Nocturnal Council.
  • applies priority-of-soul to astral theology — re-deploys the Laws X argument that soul is prior to body to prove the heavenly bodies are intelligent gods (982), a conclusion Laws X does not itself draw.
  • contrasts with theory-of-forms — substitutes mathematical astronomy and the visible cosmic gods for the intelligible Forms, which make no appearance; this absence is the standard marker of non-Platonic authorship.
  • contrasts with form-of-the-good — number and the cosmic order occupy the place the Form of the Good holds in the Republic ("number causes all good things," 977d), a mathematized substitute rather than the Good itself.
  • contradicts plato-timaeus regarding the elements — posits ether as a fifth body (981c) against the Timaeus's four elements, a proto-Aristotelian divergence within Platonic cosmology.
  • requires statesmanship — supplies the Nocturnal Council's curriculum, the supreme study its rulers must master, completing what Laws XII deferred.
  • contrasts with plato-republic — the graded mathematical curriculum echoes Republic VII's mathematical ascent but terminates in astral theology and the visible gods rather than in dialectic toward the Good.
