ΠΑΡΑΛΟΓΙΣΜΟΣ

LEXARITHMOS 805

Paralogismos, a pivotal concept in ancient Greek logic, describes an argument that, while appearing sound, contains a hidden flaw. It is not merely a mistake, but a systematic deviation from correct reasoning, often with the intent to deceive. Its lexarithmos (805) is numerically linked to the complexity of thought and the necessity for clarity.

REPORT ERROR

Definition

In classical Greek philosophy, particularly in Aristotelian logic, paralogismos (παρά + λογίζομαι) refers to a fallacious argument, a logical fallacy. It is not a simple error of ignorance or a mistake in judgment, but a systematic deviation from the rules of correct thought, often intended to mislead the interlocutor or to achieve a seemingly valid conclusion.

Aristotle, in his works «Sophistical Refutations» and «Topics», thoroughly analyzes the types of paralogisms, distinguishing them into those dependent on language (in dictione) and those independent of language (extra dictionem). This distinction formed the basis for understanding logical errors in Western philosophy for centuries. Paralogismos is, therefore, the intellectual act or its result, by which one reasons incorrectly, leading to conclusions that do not logically follow from the premises.

The concept is not limited to formal logic but extends to everyday thought, where it can refer to any erroneous estimation, miscalculation, or irrational thought. In rhetoric, paralogismos is a tool employed by sophists to persuade an audience through deceptive arguments, undermining truth in favor of persuasion.

Etymology

paralogismos ← pará + logízomai. The root LOG- derives from the Ancient Greek verb légō («to say, to collect, to reckon»).
The word «paralogismos» is a compound, originating from the preposition «pará» and the verb «logízomai». The preposition «pará» here denotes deviation, opposition, or an incorrect direction (e.g., «pará to déon» – contrary to what is proper, «pará phýsin» – contrary to nature). The verb «logízomai» means «to think, to calculate, to reason». Consequently, paralogismos signifies the act of thinking «pará» (contrary to) correct logic, i.e., reasoning falsely or calculating erroneously. The root LOG- is Ancient Greek and belongs to the oldest stratum of the language, connecting speech, collection, and thought.

From the same root LOG- derive many words related to thought, speech, and calculation. The noun «lógos» (from légō) forms the heart of this family, meaning both speech and reason. The verb «logízomai» is the active form of thinking, while «logikós» describes that which is in accordance with reason. Other cognate words include «syllogismós» (a compound form of reasoning), «apología» (a reasoned defense), and «diálogos» (a conversation).

Main Meanings

  1. Fallacious argument, logical fallacy — The primary meaning in Aristotelian logic: an argument that appears valid but contains a hidden flaw.
  2. Erroneous calculation or estimation — A more general usage referring to any mistake in thought or calculation, not necessarily with intent to deceive.
  3. Irrational thought or action — In a broader context, referring to something contrary to reason or common sense.
  4. Deception, trickery — Often, paralogismos is used with the intention to mislead or deceive the interlocutor.
  5. Sophistical device — In rhetoric, a technique used by sophists to persuade through deceptive arguments.
  6. False reasoning — The process by which one arrives at a conclusion that does not logically follow from the premises.

Word Family

LOG- (root of the verb légō)

The root LOG- is one of the most productive and semantically rich roots in the Ancient Greek language. It derives from the verb légō, which originally meant «to collect, to choose» and later «to say, to speak, to think, to reckon». This dual meaning—of gathering/ordering and of speaking/thinking—gave rise to a vast family of words covering the spectrum from simple speech and narrative to scientific logic, philosophy, and theology. Each member of the family develops one aspect of this multifaceted root, whether as an action (verb), a quality (adjective), or a result (noun).

λέγω verb · lex. 338
The original verb from which the root LOG- derives. It means «to collect, to choose», and later «to say, to speak, to think, to reckon». It is the basis for all words related to speech and reason.
λόγος ὁ · noun · lex. 373
One of the most significant Greek words. It means «speech, word, narrative, reason, cause, proportion, calculation». In Aristotelian philosophy, it is the faculty of reasoning, while in Heraclitus, it is the cosmic principle of order. In the New Testament, it acquires a theological dimension as the «Word» of God.
λογίζομαι verb · lex. 241
Means «to think, to calculate, to reason, to consider». It is the verb describing the active process of thought and reckoning, from which paralogismos directly derives as an erroneous form of this process.
λογικός adjective · lex. 403
That which is in accordance with reason, logical, rational. It describes the quality of correct thought, in contrast to paralogismos, which is a deviation from it. It is used to characterize both people and arguments.
λογική ἡ · noun · lex. 141
The science of correct thought and reasoning. As a philosophical discipline, it was systematically developed by Aristotle, who established the rules for avoiding paralogisms and achieving valid conclusions.
συλλογισμός ὁ · noun · lex. 1253
A type of logical argument where a conclusion is inferred from two or more premises. Aristotle defined it as «a discourse in which, certain things being stated, something other than what is stated follows of necessity from their being so». A paralogismos is a seeming syllogism.
ἀπολογία ἡ · noun · lex. 265
A speech of defense, a reasoned answer. It involves providing logical arguments to defend a position or action, as in Plato's «Apology of Socrates».
διάλογος ὁ · noun · lex. 256
A conversation between two or more persons. In Platonic works, dialogue is the primary method of philosophical inquiry, where through the exchange of words, the discovery of truth and the avoidance of paralogisms are sought.

Philosophical Journey

The concept of paralogismos has a long history in Greek thought, from the Presocratics to the Byzantine era:

5th C. BCE
Presocratics and Sophists
Sophists, such as Protagoras and Gorgias, frequently employed arguments that could be characterized as paralogisms, focusing on persuasion rather than truth. Zeno of Elea, with his paradoxes, laid the groundwork for the analysis of logical errors.
4th C. BCE
Plato and Aristotle
Plato, in his «Sophist», condemned sophistical practices. Aristotle, however, was the one who systematized the concept in his «Topics» and especially in «Sophistical Refutations», where he classified paralogisms and provided methods for their identification. This marked the formal entry of the term into scientific logic.
3rd C. BCE - 2nd C. CE
Hellenistic Period (Stoics)
The Stoics, with their development of propositional logic, continued the analysis of logical fallacies, albeit with a different approach from Aristotle. The term «paralogismos» retained its meaning as a fallacious argument.
1st C. BCE - 2nd C. CE
Roman Period
Latin authors and philosophers, such as Cicero, translated and commented on Aristotle's works, disseminating the concept of paralogismos into Latin as «fallacia» or «paralogismus».
3rd - 6th C. CE
Late Antiquity and Neoplatonism
Commentators on Aristotle, such as Porphyry and Simplicius, continued to analyze paralogisms, keeping their teachings alive and transmitting them to the Byzantine and Arabic traditions.
Byzantine Period
Byzantine Philosophy
Byzantine scholars preserved and studied Aristotelian logic, with paralogismos remaining a key term in the analysis of arguments, in both philosophical and theological texts.

In Ancient Texts

Three characteristic passages that highlight the concept of paralogismos:

«ἔστι δὲ παραλογισμὸς συλλογισμὸς φαινόμενος.»
A paralogism is a seeming syllogism.
Aristotle, Sophistical Refutations 164a20
«οἱ μὲν γὰρ σοφισταὶ καὶ οἱ ἐριστικοὶ παραλογίζονται τοὺς ἀνθρώπους.»
For the sophists and the contentious mislead men by false reasoning.
Aristotle, Topics 100b25
«πᾶς γὰρ ὁ παραλογισμὸς ἀπὸ τῆς ἀγνοίας γίνεται.»
For every paralogism arises from ignorance.
Plutarch, On the Education of Children 10C

Isopsephic Words (805)

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (805), but different roots:

παραδιαστολή
«Paradiastolē» means «distinction, separation». While paralogismos confuses, paradiastolē seeks clarity, conceptually opposing the effort for correct thought.
δολοφονία
«Dolophonía» means «murder by treachery, homicide». It is an act characterized by cunning and deception, just as paralogismos can be an intellectual act with deceptive intent, though in a different domain.
περικόσμιος
«Perikósmios» means «very orderly, well-arranged». This word contrasts with the disorder and inconsistency that characterize a paralogismos, emphasizing the value of order and precision.
ἐγκατάκλεισις
«Enkatákleisis» means «imprisonment, confinement». While paralogismos can «imprison» thought in erroneous conclusions, the word refers to physical restriction, showing the variety of meanings the same number can carry.
ἐμπειροπόλεμος
«Empeirópolēmos» is one who is «experienced in war». This word, though belonging to a completely different semantic field, denotes skill and knowledge, in contrast to the error of paralogismos.
