Meno
Plato's short dialogue on whether virtue can be taught — and the famous slave-boy demonstration of recollection
Tradition: Classical Greek philosophy / Platonism
Can virtue be taught? — and the slave-boy who, asked questions, recovers geometric truth he never learned
The Meno is one of Plato's most-read short dialogues and the canonical text of the recollection doctrine (anamnesis). Meno, a young Thessalian aristocrat, asks Socrates whether virtue can be taught. The dialogue's most famous moment is the slave-boy demonstration — Socrates leads an uneducated slave-boy, by careful questioning alone, to recover the doubling-of-the-square theorem; the conclusion, Socrates argues, is that the soul must have known mathematical truths in a prior existence and merely recollects them in this life. The Meno is the bridge between the early Socratic dialogues and the middle-period theory of Forms, and the founding text of the philosophical tradition that mathematical knowledge is a priori.

School Embodiments
The Meno is one of the founding texts of the recollection doctrine — central to Platonist epistemology and to the Theory of Forms.
"As the soul is immortal, has been born often and has seen all things here and in the underworld, there is nothing which it has not learned." (Meno 81c)
The Meno is the founding ancient text for the rationalist doctrine of innate ideas / a priori mathematical knowledge. Descartes, Leibniz, and Chomsky all cite it.
"Learning is recollection." (Meno 81d, the central thesis)
The Meno's argument that mind has access to eternal truths independent of sense experience is one of the philosophical ancestors of idealist epistemology.
"What you call seeking, then, is really not seeking; it is recollecting." (Meno 81d)
Geometric truths are real and discoverable by reason — the foundation of the Platonic tradition's mathematical realism.
"True opinions are valuable as long as they remain, but their fastenings are loosed." (Meno 97e, on the difference between knowledge and mere true belief)
Plotinus's account of the soul's pre-existent contemplation of the Forms develops directly from the Meno's recollection doctrine.
"The soul that has seen the most truth shall be incarnated in the philosopher." (Phaedrus 248d, consonant with the Meno)
Augustine's divine-illumination theory of knowledge is a Christianised version of the Meno's recollection. Aquinas modifies it further toward an empirical-abstraction account, but the Meno remains an authority for both.
"The greatest knowledge is to know that one does not know." (paraphrasing the Socratic puzzle of inquiry, Meno 80d)
Modern philosophy of mathematics (Gödel, Frege in his Platonist mood) engages the Meno as the founding text of mathematical realism.
"The mind is so constituted that whenever it sees a true mathematical principle, it must assent." (paraphrasing Meno 85b on the slave-boy)
Internal Tensions
Whether the recollection doctrine is meant as literal pre-existence or as a metaphor for some other epistemic capacity has been disputed since antiquity. The slave-boy passage has been read as a genuine argument for innatism (Chomsky), as a faulty argument that mistakes guidance for recollection (most empirical epistemologists), and as a literary illustration whose philosophical work is more limited than Plato suggests.
I. Time
The soul exists before and after this life; reincarnation is the background framework.

II. Space
Not engaged.
Attributes
III. Matter
The slave-boy's discovery is mathematical, not material — emphasising the priority of the intelligible.
Attributes
IV. Observer
The Meno's soul is plural empirically but bears eternal truths from prior contemplation. Knowledge is total in principle (the soul has seen everything); learning is recovery.
Attributes
V. Energy
Not engaged.
Attributes
VI. Information
The Forms are substantival informational structures accessible to soul. Personal information conserved across reincarnations.
