ΨΕΥΣΙΣ

LEXARITHMOS 1515

Pseusis (ψεῦσις), as the act of lying or deceiving, represents a fundamental philosophical and ethical problem in ancient Greek thought. From the Homeric era, where deception was a tactic of war, to the Sophists who questioned the very notion of truth, and Plato who categorized it as a form of error, pseusis was examined in terms of its nature, causes, and consequences. Its lexarithmos (1515) reflects the complexity and gravity of the concept.

REPORT ERROR

Definition

According to the Liddell-Scott-Jones Lexicon, ψεῦσις (a feminine noun) primarily means "the act of lying, deception." The word derives from the verb ψεύδομαι, "to lie, to deceive." In classical Greek thought, ψεῦσις is not merely the presentation of untrue information but is often associated with the intention to mislead and the ethical dimension of deceit.

In philosophy, ψεῦσις is examined on multiple levels. In epistemology, it concerns the discrepancy between discourse and reality, the deviation from ἀλήθεια (truth). In ethics, it pertains to the speaker's intention to mislead, rendering the act morally reprehensible. Plato, for instance, in his "Republic," distinguishes between "true falsehood" (ἐν ταῖς ψυχαῖς ψεῦδος), which is the ignorance and error of the soul, and "falsehood in words" (ψευδός ἐν λόγοις), which can even be a "noble lie" (γενναῖον ψεῦδος) for the good of the city, though it remains a falsehood.

Aristotle, in his "Metaphysics" and "On Interpretation," primarily examines ψεῦσις as a property of judgment or proposition, where a statement is false if what it asserts does not correspond to reality. Ψεῦσις, in this context, is the opposite of ἀλήθεια, which is defined as the agreement of discourse with things. The distinction between ψεῦσις as cognitive error and as an ethical act of deception remains central to understanding the word.

Etymology

ψεῦσις ← ψεύδομαι ← pseud- (Ancient Greek root belonging to the oldest stratum of the language)
The root pseud- is an ancient Greek root belonging to the oldest stratum of the language, with no apparent extra-Hellenic cognates. From this root derive words related to the concept of untruth, deception, and error. The meaning of the root is stable throughout the history of the Greek language, denoting a deviation from truth or reality, whether voluntary or involuntary.

From the root pseud- many derivatives are formed with various morphological endings. The verb ψεύδομαι constitutes the primary form, from which nouns like ψεῦσις (the act of lying) and ψεῦδος (the lie, the untruth) are formed. Also, adjectives such as ψευδής (false, untrue, deceitful) and ἀψευδής (truthful, not lying). Compound words like ψευδολόγος (liar) and ψευδοπροφήτης (false prophet) demonstrate the root's productivity across different semantic fields.

Main Meanings

  1. The act of lying, deception — The primary meaning, the action of uttering untrue statements, with or without intent.
  2. The lie, untruth — The content of the false statement, that which is not true.
  3. Error, cognitive mistake — In epistemology, the state of the soul that believes something untrue, without necessarily intending to deceive. (Plato, "Sophist")
  4. Fraud, trickery — Deliberate misleading, the use of falsehood to achieve a certain purpose.
  5. False appearance, pretense — The external manifestation that does not correspond to internal reality.
  6. Falsehood, slander — The dissemination of false reports, often with malicious intent.
  7. Theological pseusis — Deviation from divine truth, distortion of the divine word, as in the false prophets of the New Testament.

Philosophical Journey

The concept of ψεῦσις traverses Greek thought from the earliest times, evolving from a practical aspect of daily life and warfare into a central philosophical and ethical problem.

8th C. BCE
Homeric Era
In Homeric epics, deception (ἀπάτη, δόλος) is often a means to achieve goals, especially in war (e.g., Odysseus). Ψεῦσις does not yet carry the negative ethical connotation it would later acquire.
5th C. BCE
Sophists and Presocratics
Sophists, such as Gorgias, questioned the possibility of truth itself, making ψεῦσις relative. The distinction between discourse and reality became a subject of intense debate.
4th C. BCE
Plato
In the "Republic" and "Sophist," Plato analyzes the nature of ψεῦσις, distinguishing "falsehood in the soul" (ignorance) from "falsehood in speech" (statement). He introduces the idea of a "noble lie" for the good of the city, but always considers it inferior to truth.
4th C. BCE
Aristotle
In his logical works, Aristotle defines ψεῦσις as the non-correspondence between a judgment or proposition and reality. A proposition is false if it states that something is when it is not, or that it is not when it is.
3rd C. BCE - 2nd C. CE
Stoics
The Stoics placed great emphasis on avoiding false judgments (φαντασιῶν) as a necessary precondition for ataraxia and eudaimonia. Ψεῦσις was considered a result of incorrect assent.
1st-2nd C. CE
New Testament
Ψεῦσις acquires a strong ethical and theological dimension. The devil is characterized as the "father of lies" (John 8:44), while false prophets and false teachers are condemned as enemies of divine truth.

In Ancient Texts

Ψεῦσις, as a central concept in ancient thought, occupied many writers. Below are three characteristic passages:

«τὸ γὰρ ἀληθὲς ψεῦδος, εἰ οἷόν τε τοῦτο εἰπεῖν, πάντες ἄνδρες καὶ θεοὶ μισοῦσι.»
For the true falsehood, if it is possible to say this, all men and gods hate.
Plato, Republic 382a
«τὸ μὲν γὰρ ψεῦδος ἐν τῷ λέγειν τὸ μὴ ὂν εἶναι ἢ τὸ ὂν μὴ εἶναι.»
For falsehood consists in saying that what is not, is, or that what is, is not.
Aristotle, Metaphysics Θ 1051b3-5
«ὑμεῖς ἐκ τοῦ πατρὸς τοῦ διαβόλου ἐστὲ, καὶ τὰς ἐπιθυμίας τοῦ πατρὸς ὑμῶν θέλετε ποιεῖν. ἐκεῖνος ἀνθρωποκτόνος ἦν ἀπ’ ἀρχῆς, καὶ ἐν τῇ ἀληθείᾳ οὐκ ἔστηκεν, ὅτι οὐκ ἔστιν ἀλήθεια ἐν αὐτῷ. ὅταν λαλῇ τὸ ψεῦδος, ἐκ τῶν ἰδίων λαλεῖ, ὅτι ψεύστης ἐστὶν καὶ ὁ πατὴρ αὐτοῦ.»
You are of your father the devil, and your will is to do your father's desires. He was a murderer from the beginning, and has nothing to do with the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies.
Gospel of John, 8:44
