ΕΠΙΔΙΟΡΘΩΤΙΚΟΝ

LEXARITHMOS 1538

That which corrects, which restores proper order. In Aristotelian philosophy, τὸ ἐπιδιορθωτικόν often refers to corrective justice, aiming to re-establish balance when it has been disturbed. Its lexarithmos (1538) suggests a complex process of restoration and perfection.

REPORT ERROR

Definition

Τὸ ἐπιδιορθωτικόν (the neuter form of the adjective ἐπιδιορθωτικός) signifies "that which has the property of correcting, restoring, or rectifying." As a substantivized adjective, it describes the quality or function of correction, the re-establishment of a proper state, or the amendment of an error.

The word acquires particular significance in Aristotelian philosophy, primarily in the "Nicomachean Ethics," where it is used to describe "corrective justice" (τὸ ἐπιδιορθωτικὸν δίκαιον). This form of justice is applied to transactions and interactions between individuals, aiming to restore the equality that has been disturbed by an injustice. In contrast to distributive justice, corrective justice does not consider the worth of the persons involved but the equality of the things, seeking to balance the loss of one party with the gain of the other.

Beyond its Aristotelian usage, ἐπιδιορθωτικόν can refer more generally to anything that has a corrective, therapeutic, or ameliorative character. The concept of "correctness" (ὀρθότης) is central, implying a return to a standard, a rule, or an ideal state, whether moral, legal, or practical.

Etymology

ἐπιδιορθωτικόν ← ἐπιδιορθόω ← ὀρθ- (root of ὀρθός, meaning 'straight, right')
The root ὀρθ- is an Ancient Greek root belonging to the oldest stratum of the language, expressing the concept of straightness, correctness, and accuracy. From it derive words denoting physical straightness, moral rectitude, and the action of correcting or restoring. Τὸ ἐπιδιορθωτικόν is formed from the verb ὀρθόω ('to make straight, correct') with the addition of the prefixes ἐπί- (denoting addition, repetition, or purpose) and διά- (denoting through, thoroughly, or intensive action), as well as the adjectival suffix -τικός, which indicates capability or fitness for something.

Cognate words include ὀρθός ('straight, right, correct'), ὀρθόω ('to make straight, correct'), διόρθωσις ('correction, amendment'), ἐπανόρθωσις ('restoration, correction, improvement'), ὀρθῶς ('rightly, correctly'), ὀρθότης ('straightness, correctness, rectitude'), ὀρθοτομία ('right division, accurate cutting'), and ὀρθογραφία ('correct writing'). All these words retain the core meaning of correctness and alignment, whether on a physical or metaphorical level.

Main Meanings

  1. That which has the property of correcting or restoring — The primary meaning, referring to anything capable of bringing something back to its proper state.
  2. (Philosophy, Aristotle) Pertaining to corrective justice — The specific usage in the "Nicomachean Ethics" for justice that restores equality in transactions.
  3. That which aims at rectifying an injustice or error — The application of the concept in ethical or legal contexts for re-establishing order.
  4. That which brings back to the proper state or order — A more general meaning implying a return to a standard or rule.
  5. Ameliorative, reformative — Anything that contributes to the improvement or reform of a situation or system.
  6. (Rare, medical) Therapeutic, palliative — In certain contexts, it may refer to remedies or practices that correct an ailment or alleviate symptoms.

Word Family

ὀρθ- (root of ὀρθός, meaning 'straight, right')

The root ὀρθ- is an Ancient Greek root belonging to the oldest stratum of the language, expressing the concept of straightness, correctness, and accuracy. From it derive words denoting physical straightness, moral rectitude, and the action of correcting or restoring. This family is fundamental for understanding Greek thought concerning order, justice, and truth, as 'correctness' (ὀρθότης) is not merely the absence of error but the active alignment with a standard or rule. Each member of the family highlights a different facet of this central idea.

Philosophical Journey

The concept of correction and the restoration of correctness is ancient in Greek thought, but the specific word ἐπιδιορθωτικόν acquires its central philosophical meaning with Aristotle.

5th-4th C. BCE
Presocratics and Plato
The concepts of 'correctness' (ὀρθότης) and 'straightness' are present, but the compound word ἐπιδιορθωτικόν is not used with its specific philosophical meaning. Plato discusses right judgment and proper governance.
4th C. BCE
Aristotle
Aristotle establishes the term "τὸ ἐπιδιορθωτικὸν δίκαιον" in the "Nicomachean Ethics" (Book V) as a central concept of corrective justice, which restores equality in transactions. This is the most influential use of the word.
Hellenistic Period
Rhetoric and Legal Texts
The word and its cognates (διόρθωσις, ἐπανόρθωσις) are widely used in rhetorical treatises for correcting speeches and in legal texts for amending laws or restoring rights.
Roman Period
Commentary and Continuation
Commentators on Aristotle continue to analyze the concept of corrective justice. The word retains its meaning in philosophical and legal contexts, influencing Roman legal thought.
Byzantine Period
Theological and Legal Use
In Byzantine literature, the concept of correction and rectification is present in theological texts (e.g., for the correction of morals) and in legal codes, continuing the classical tradition.

In Ancient Texts

The most characteristic passage for ἐπιδιορθωτικόν comes from Aristotle's "Nicomachean Ethics," where the function of corrective justice is defined:

«τὸ γὰρ ἐπιδιορθωτικὸν δίκαιον ἐν συναλλάγμασι μὲν ἔστιν, ἐν οἷς ἑκούσιον καὶ ἀκούσιον τὸ ἄδικον.»
For corrective justice is found in transactions, both voluntary and involuntary, where injustice occurs.
Aristotle, Nicomachean Ethics V.4.1132a

Isopsephic Words (1538)

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (1538) as ἐπιδιορθωτικόν, but from different roots, offer interesting conceptual parallels:

ὁλοκλήρωσις
Ὁλοκλήρωσις (1538), meaning 'completeness' or 'perfection', connects with τὸ ἐπιδιορθωτικόν as correction often aims to restore wholeness or an ideal state to something that has been disturbed.
ὑπόλημψις
Ὑπόλημψις (1538) refers to an assumption, opinion, or conception. Correction (ἐπιδιορθωτικόν) is often applied to erroneous assumptions or judgments, making this concept an object of the corrective process.
προσομολογέω
The verb προσομολογέω (1538) means 'to agree, acknowledge, confess'. The act of correction often requires the acknowledgment of an error and the confession of the need for rectification, creating a conceptual bridge with ἐπιδιορθωτικόν.
διευθετέω
The verb διευθετέω (1538) means 'to set right, arrange properly, correct'. Although it derives from a different root (εὐθύς, 'straight'), its meaning is almost identical to that of ἐπιδιορθωτικόν, highlighting a common Greek emphasis on re-establishing proper order.
ἐπιλελογισμένως
The adverb ἐπιλελογισμένως (1538) means 'with calculation, deliberately, advisedly'. The application of ἐπιδιορθωτικόν, especially in Aristotelian justice, requires careful thought and rational assessment, making this isopsephic word particularly apt.
νομορήτωρ
The νομορήτωρ (1538) was an orator who interpreted or defended laws. The concept of correction is central to the legal framework, where the νομορήτωρ might seek to restore legal correctness, thus linking the two words.
