ΑΝΤΙΦΑΣΙΣ

LEXARITHMOS 1272

Antiphasis — «contradictory statement» — is perhaps the most basic logical category of Western philosophy. Aristotle in the Metaphysics and Posterior Analytics established the principle of non-contradiction as the «firmest of all principles»: nothing can be and not be the same thing simultaneously. On this statement rests the whole edifice of classical logic. From the Stoics to medieval scholasticism and finally to modern logic, antiphasis remains a non-negotiable structure of thought.

Definition

According to the Liddell-Scott-Jones Lexicon, ἡ ἀντίφασις means «contrary statement, contradiction, dispute». It is formed from ἀντί (against) and φάσις (statement, declarative act, from the verb φημί). Literally: «a statement against another statement». In formal logic, antiphasis is the relation between two propositions that cannot simultaneously be true nor simultaneously be false: «X is Y» and «X is not Y».

The full philosophical significance of antiphasis comes with Aristotle. In Book IV of the Metaphysics (Γ 3, 1005b18-23) he formulates the Principle of Non-Contradiction: «The same thing cannot at the same time both belong and not belong to the same thing and in the same respect». It is the «most certain of all principles» — it cannot be demonstrated or refuted without presupposing itself. In the Posterior Analytics he distinguishes antiphasis from contraries: contradictory propositions exhaust all possible cases, contraries do not.

The Stoics developed propositional logic around relations of antiphasis. In the medieval period, the scholastic work of Abelard, Thomas Aquinas, and Ockham deepened the Aristotelian analysis. In the modern age, Frege and Russell formulated it formally (¬(p ∧ ¬p)), while Hegel proposed a dialectical version in which contradiction is a driving force.

Etymology

ἀντίφασις ← ἀντί (against) + φάσις (statement, from φημί)
The root φα- / φη- (φημί, to say) comes from PIE *bʰeh₂- (to speak, declare), whence Latin fari (to say), fama (fame), fatum (spoken destiny). Phasis is the declaration, the assertoric proposition, often used as a technical term in logic. Anti-phasis is the counter-declaration: when someone says «X holds», the contradiction is «X does not hold». The precision of the pair ensures the binary classification of propositions into true and false.

Cognates: φημί, φάσις, ἀπόφασις, κατάφασις, φάσκω, φατικός. Logical terms: ἀντίθεσις, ἐναντία, ἀντικείμενα, διάζευξις. Latin parallels: contradictio, contradictorius. Opposites: ὁμολογία, συμφωνία, ταυτολογία.

Main Meanings

  1. Contrary statement — The basic meaning — the proposition that negates another proposition.
  2. Logical contradiction — Two propositions that cannot simultaneously be true nor simultaneously false.
  3. Principle of non-contradiction — The Aristotelian fundamental principle: nothing can at the same time be and not be.
  4. Pair of contradictory propositions — In the syllogistic, the complete disjunction that exhausts every possible case.
  5. Dispute, denial — In forensic and political rhetoric, the expression of an opposing opinion or refusal.
  6. Dialectical contradiction — In Hegel, contradiction becomes the internal dynamic that drives the dialectical process.
  7. Real contradiction — In the Marxist tradition, social and historical contradictions as driving forces of change.
  8. Formal contradiction — In modern mathematical logic, the symbolic expression ¬(p ∧ ¬p) as an axiom.

Philosophical Journey

Antiphasis, from an Aristotelian axiom, became the stable center of Western logic, running through ancient, medieval, modern, and contemporary philosophers.

5th c. BCE
Heraclitus
In his fragments he presents opposites as simultaneously valid («the way up and down is one and the same»), a position Aristotle will reject as a violation of the principle of non-contradiction.
5th c. BCE
Parmenides, Zeno
Pioneers of logical analysis. Parmenides in On Nature argues that not-being cannot exist — implying the principle of contradiction. Zeno uses paradoxes of reductio ad absurdum.
4th c. BCE
Plato
In the Sophist (254d-257a) and the Parmenides he analyzes the relation of being-not-being, identity-otherness. Antiphasis becomes a central logical term, though without later rigor.
4th c. BCE
Aristotle
Establishes the Principle of Non-Contradiction in Metaphysics Γ (1005b-1007a). Formulates the «law of excluded middle» in De Interpretatione (18a28-19b4). Definitively codifies the logical concept.
3rd c. BCE
Chrysippus, Stoics
Develop propositional logic with five indemonstrable axioms, all grounded in relations of antiphasis. Stoic logic will remain superior to Aristotelian until the 19th century.
13th c. CE
Thomas Aquinas
In In Metaphysicorum and the Summa Theologiae, the principle of non-contradiction is «according to nature» — the foundation of all human knowledge and theology.
19th c. CE
Hegel
In the Science of Logic he rejects the static Aristotelian view and proposes dialectical contradiction as the motive force of self-developing thought.
19th–20th c. CE
Frege, Russell, Wittgenstein
Formal logic codifies contradiction as ¬(p ∧ ¬p) and the law of excluded middle as (p ∨ ¬p). Russell discovers paradoxes that shake the foundations.
