ΚΑΚΟΔΟΞΙΑ

LEXARITHMOS 256

Kakodoxia, a compound word combining "kakos" (bad) and "doxa" (opinion), initially describes an erroneous or harmful opinion. In philosophy, it denotes a flawed perception or doctrine, while in the Christian world, it evolved into a technical term for heresy, signifying a deviation from orthodox belief. Its lexarithmos (256) can be associated with the idea of disagreement or divergence from the correct path.

Definition

According to the Liddell-Scott-Jones Lexicon, kakodoxia is "bad opinion, heterodoxy, heresy." The word is a compound of the adjective "kakos" (bad, harmful, erroneous) and the noun "doxa" (opinion, perception, belief, reputation). In classical Greek literature, its usage is relatively rare, but when it appears, it refers to an opinion deemed incorrect or detrimental.

The significance of kakodoxia gained particular weight in philosophical circles, where it could refer to a doctrine that contravenes sound reason or truth, as defined by a specific school of thought. For instance, the Stoics might characterize the Epicureans' views on pleasure as the highest good as kakodoxia.

The most widespread and technical use of the word developed in the Christian world, where kakodoxia became synonymous with heresy. It describes any teaching or belief that deviates from the dogma of the Church, considered spiritually harmful and dangerous for the soul. In this context, kakodoxia is explicitly contrasted with orthodoxy, the correct and accepted belief.

Etymology

kakodoxia ← kakos + doxa (a compound word from the roots kak- and dok-)
Kakodoxia is a compound word derived from the adjective kakos and the noun doxa. Kakos, with its root kak-, denotes negative quality, bad nature, or moral deficiency. Doxa, with its root dok-, originally signified "opinion, perception, expectation" and later "reputation, honor, glory." The synthesis of these two elements creates a word describing an opinion or belief that is erroneous, harmful, or morally reprehensible. The concept evolved from a simple "bad opinion" to "erroneous doctrine" or "heresy" in the Christian world.

From the root kak- derive numerous words such as kakia, kakos, kakopoios, kakoētheia. From the root dok- derive words such as dokeō, dokimos, dogmatizō, dogma. Kakodoxia represents an example of compounding where the negative prefix kakos intensifies the erroneous nature of doxa, creating a new meaning that transcends the sum of its parts.

Main Meanings

  1. Initial bad opinion or judgment — The simple notion of an incorrect or mistaken view on something.
  2. Erroneous philosophical doctrine — A theory or dogma considered incorrect by another philosophical school.
  3. Bad repute, disrepute — The negative perception others have of someone or something, stemming from "doxa" as reputation.
  4. Heterodoxy, heresy — The theological meaning of deviation from correct belief or the official dogma of the Church.
  5. Harmful teaching — Any doctrine considered to lead to moral or spiritual harm.
  6. Error, delusion — The state of being mistaken, especially in matters of faith or knowledge.

Word Family

kak- and dok- (roots of kakos and dokeō)

Kakodoxia is a characteristic example of a compound word in Ancient Greek, arising from the combination of two potent roots: the root kak- (denoting bad, erroneous, harmful) and the root dok- (related to opinion, perception, reputation). The coexistence of these roots generates a family of words that explore the various facets of mistaken judgment, negative quality, and distorted perception, both on a personal and on a collective or dogmatic level. Each member of the family illuminates a different aspect of this complex meaning.

κακός adjective · lex. 311
The primary root of negative quality, meaning "bad, harmful, ugly, erroneous." It forms the first component of kakodoxia, imparting the negative connotation to the opinion. Widely used throughout Ancient Greek literature, from Homer to the philosophers.
δόξα ἡ · noun · lex. 135
The second primary root, meaning "opinion, perception, expectation" and later "reputation, honor, glory." In kakodoxia, it refers to the erroneous opinion or doctrine. In Plato, doxa is often contrasted with epistēmē (knowledge) or alētheia (truth), as a form of uncertain cognition.
δοκέω verb · lex. 899
The verb from which doxa derives, meaning "to think, believe, seem, decide." It describes the process of forming an opinion or perception, which in the case of kakodoxia is erroneous. Frequently appears in philosophical texts, such as those by Aristotle, for expressing subjective judgments.
κακία ἡ · noun · lex. 52
A noun derived from kakos, meaning "wickedness, malice, cowardice." It represents the ethical dimension of evil, an internal state that can lead to kakodoxia or erroneous judgments. Extensively analyzed by Aristotle in his Nicomachean Ethics.
δόγμα τό · noun · lex. 118
Derived from dokeō, meaning "opinion, decision, decree, doctrine." In philosophy, it refers to a principle or theory, while in theology, to an official belief. Kakodoxia is the deviation from correct dogma. For the Stoics, dogmata were the fundamental principles of their philosophy.
ὀρθοδοξία ἡ · noun · lex. 394
The antonym of kakodoxia, meaning "correct opinion, correct teaching, correct belief." It is a compound of orthos (right, correct) and doxa. It became established as a technical term in Christianity to denote the official and accepted faith, in contrast to heresy/kakodoxia.
κακοποιός adjective · lex. 541
Compound of kakos and poieō (to make, do), meaning "evil-doer, criminal." While not directly referring to opinion, its existence shows how the root kak- connects to action, suggesting that kakodoxia can lead to harmful acts or detrimental consequences.
κακοήθεια ἡ · noun · lex. 144
Compound of kakos and ēthos (character, custom), meaning "bad character, malice, ill-nature." It describes a negative moral quality that can influence judgment and lead to the adoption of kakodoxiai or the deliberate distortion of truth.

Philosophical Journey

The trajectory of kakodoxia reflects the evolution of the concept of "correct opinion" from philosophy to theology.

5th-4th C. BCE
Classical Greek
The word kakodoxia is rare in the classical period. Philosophers more often used phrases like «κακὴ δόξα» to describe an erroneous opinion or perception, without a unified term existing.
3rd-1st C. BCE
Hellenistic Philosophy
In Hellenistic philosophical texts, such as those by Plutarch, kakodoxia begins to be used to characterize the mistaken theories or doctrines of other schools, particularly concerning ethical or metaphysical issues. (Plutarch, *De Stoicorum Repugnantiis* 1040c).
1st C. BCE - 1st C. CE
Philo of Alexandria
Philo, the Hellenistic Jewish philosopher, uses kakodoxia to refer to erroneous religious or philosophical conceptions, bridging the word's use between Greek philosophy and early theology. (Philo, *De Vita Mosis* 2.193).
1st-2nd C. CE
New Testament and Apostolic Fathers
Although the word does not appear in the New Testament, the concept of false teaching (ψευδοδιδασκαλία) is central. Among the Apostolic Fathers, kakodoxia begins to be used to describe the early Christian heresies.
3rd-4th C. CE
Patristic Theology
Kakodoxia is established as a technical term for heresy and heterodoxy. Church Fathers, such as Origen and Athanasius, systematically use it in their anti-heretical treatises to distinguish correct from erroneous belief. (Origen, *Contra Celsum* 6.13).
5th-15th C. CE
Byzantine Period
Throughout the Byzantine era, kakodoxia remained a key term in theological discussions and synodal decisions, referring to any deviation from Orthodox teaching.

In Ancient Texts

Kakodoxia, as a concept, engaged philosophers and theologians, as evidenced in the following passages:

«τῆς κακοδοξίας»
of the bad opinion / erroneous doctrine
Plutarch, *De Stoicorum Repugnantiis* 1040c
«κακοδοξίας ἁπάσης»
of all bad opinion / heresy
Philo of Alexandria, *De Vita Mosis* 2.193
«τῆς κακοδοξίας»
of the heresy
Origen, *Contra Celsum* 6.13

Isopsephic Words (256)

Words from the Liddell-Scott-Jones Lexicon with the same lexarithmos (256) as kakodoxia, but of different roots, offer interesting comparisons:

ἀληθής
The adjective «ἀληθής» (true, real) is isopsephic with kakodoxia and represents its conceptual antithesis. While kakodoxia expresses erroneous opinion, truth embodies correct and objective knowledge, highlighting the continuous search for truth against error.
κακοκέρδεια
The noun «κακοκέρδεια» (dishonest gain, ill-gotten profit) shares the first component «κακός» with kakodoxia. Both words imply something harmful or erroneous, one in judgment and the other in action, revealing the multifaceted expression of "badness."
παλινοδία
«παλινοδία» (recantation, retraction of previous statements) is isopsephic and conceptually related, as it implies the recognition and correction of a previously erroneous opinion or doctrine, i.e., a kakodoxia. Palinodia is the path from kakodoxia to correct opinion.
διαλογίζομαι
The verb «διαλογίζομαι» (to ponder, consider, reflect) is isopsephic and refers to the intellectual process that leads to the formation of opinion. Kakodoxia can arise from erroneous deliberation, while correct deliberation leads to truth.
σέβημα
«σέβημα» (object of worship, reverence) is isopsephic and can be linked to kakodoxia, as erroneous religious conceptions (kakodoxiai) often concern correct worship or the object of reverence, leading to idolatry or heretical practices.
ἔμπνοια
«ἔμπνοια» (inspiration, breath) is isopsephic and represents spiritual enlightenment or divine guidance, which stands in opposition to kakodoxia, often considered a product of human error or demonic influence. Inspiration leads to truth, kakodoxia to delusion.
