ΕΠΑΓΓΕΛΤΙΚΟΝ (epaggeltikon) — Lexarithmos 577 · Etymology, Meanings

Definition

In ancient Greek literature, the adjective ἐπαγγελτικός, -ή, -όν generally means "pertaining to a promise or declaration" or "relating to a profession." As a noun, τὸ ἐπαγγελτικόν, it acquires a specific technical meaning in Stoic philosophy, where it is used to denote a "proposition" or "assertion" (ἀξίωμα), i.e., a complete and self-contained verbal expression that can be either true or false. It is not merely a word or a phrase, but a complete statement about reality.

The concept of the ἐπαγγελτικόν is fundamental to Stoic logic, as it constitutes the object of judgment and truth. In contrast to simple concepts or impressions, the ἐπαγγελτικόν is that which is "announced" or "declared" about something, and thus can be evaluated for its correctness. For the Stoics, the understanding and proper use of ἐπαγγελτικά were essential for achieving wisdom and ataraxia (freedom from disturbance).

The word derives from the verb ἐπαγγέλλω, which means "to announce, proclaim, promise, declare officially." Thus, the ἐπαγγελτικόν is that which has been announced or proclaimed, carrying the sense of a statement or proposition. The evolution of its meaning from "promise" to "proposition" reflects the Stoics' emphasis on precise formulation and logical analysis of discourse.

Etymology

epangelikon ← epangello ← epi + angello ← angel- (root)

The word ἐπαγγελτικόν derives from the verb ἐπαγγέλλω, which is a compound of the prefix ἐπί- and the verb ἀγγέλλω. The root ἀγγελ- is an Ancient Greek root belonging to the oldest stratum of the language, denoting the concept of announcing, conveying a message, or reporting. The prefix ἐπί- adds the sense of addition, direction, or official declaration, reinforcing the idea of a public or formal announcement.

From the root ἀγγελ- springs a rich family of words in Ancient Greek, all related to communication and announcement. The verb ἀγγέλλω is the base, from which nouns like ἄγγελος ("messenger") and ἀγγελία ("message") are derived. Through the use of prefixes, compound verbs such as παραγγέλλω ("to transmit a command"), ἀπαγγέλλω ("to report back"), and προαγγέλλω ("to announce beforehand") are formed, each enriching the basic meaning of announcement with different nuances. The ἐπαγγελτικόν, via ἐπαγγέλλω, emphasizes the formal or binding aspect of an announcement.

Word Family

angel- (root of the verb ἀγγέλλω, meaning "to announce, to bring a message")

The root ἀγγελ- forms the core of a significant family of words in Ancient Greek, all revolving around the concept of announcement, message conveyance, and declaration. From this root developed both nouns describing the messenger or the content of the message, and verbs denoting the act of announcing with various nuances, depending on the prefixes. This root is fundamental to understanding communication and proclamation in the ancient world.

Philosophical Journey

The journey of ἐπαγγελτικόν from a general concept to a specialized philosophical term illustrates the evolution of Greek thought:

5th-4th C. BCE

Classical Greek

The verb ἐπαγγέλλω is used with the meaning "to promise, to proclaim." The adjective ἐπαγγελτικός is rare, with a general meaning "pertaining to a promise."

The Stoic use of the term continues and is developed by later Stoics and commentators, such as Diogenes Laertius, who records Stoic doctrine.

4th-6th C. CE

Modern Usage

The word «επαγγελματικός» (from ἐπάγγελμα) is now common, denoting something related to a profession. The original philosophical meaning of ἐπαγγελτικόν as a proposition has been lost from common usage.

In Ancient Texts

Two characteristic passages from Diogenes Laertius, who records Stoic doctrine, illuminate the technical use of the term:

«τὸ δὲ ἐπαγγελτικὸν ἢ ἀξίωμα λέγεται, ὅπερ ἐστὶν ἀληθὲς ἢ ψεῦδος.»

That which is asserted, or a proposition, is called a statement, which is either true or false.

Diogenes Laertius, Lives of Eminent Philosophers 7.66

«τὸ δὲ ἐπαγγελτικὸν ἀξίωμα λέγεται, ὅπερ ἐστὶν ἀληθὲς ἢ ψεῦδος.»

The asserted proposition is called a statement, which is either true or false.

Diogenes Laertius, Lives of Eminent Philosophers 7.70
