ΣΥΝΕΠΕΙΑ
Synépeia, a cornerstone of ancient Greek thought, denotes consistency, logical consequence, and adherence to principle. Its lexarithmos (751) reflects the complexity of the concept, linking order with action and completion.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, synépeia (from syn- + hépomai) initially means “to follow along with, to agree, to go together.” The concept rapidly evolved to describe internal coherence and logical sequence.
In classical philosophy, synépeia constitutes a fundamental virtue and a logical principle. Plato, for instance, frequently refers to it as the harmony of the parts of a whole or the internal consistency of the soul. Consistency in action and speech is considered essential for achieving virtue and eudaimonia.
The Stoics further developed the concept, making “living in agreement with nature” (ὁμολογίαν τῇ φύσει ζῆν) the highest ideal, where consistency with the universal reason (Logos) is key to the ethical life. Synépeia is not merely the absence of contradiction but the active adherence to a rational and ethical order, both in the individual's inner world and in their external actions.
Etymology
The compound with syn- imparts the sense of simultaneous or agreed-upon following, of coherence. From this compound arise other cognate words such as the adjective synepés (one who follows, consistent) and the verb synépomai (to follow together, agree). The broader family of the root hep- includes words like épos (word, speech, sequence of thought) and épō (to be busy about, handle), underscoring the idea of sequence and continuity in various contexts.
Main Meanings
- Agreement, harmony — The state of agreement or internal coherence between parts or ideas. E.g., «ἡ τῶν λόγων συνέπεια» (the consistency of arguments).
- Logical consequence, coherence — The logical connection or sequence of ideas and arguments, where one follows the other consistently. A fundamental concept in philosophy and rhetoric.
- Steadfastness of character, adherence to principles — The moral quality of an individual who acts consistently with their principles, without contradictions. A virtue highly valued in ancient ethics.
- Result, outcome — The natural or logical consequence of an action or state. E.g., «αἱ συνέπειαι τῶν πράξεων» (the consequences of actions).
- Obligation, duty — Adherence to an agreement or promise, the keeping of commitments. Consistency as the fulfillment of one's word or duty.
- Consistency (as a quality) — The quality of being consistent, i.e., reliable, stable, and predictable in one's behavior or thought.
Word Family
hep- (root of hépomai, meaning “to follow”)
The root hep- (from Proto-Indo-European *sekʷ-) carries the primary meaning of “to follow” or “to ensue.” From this basic idea of movement and sequence, a family of words develops that describes coexistence, agreement, logical sequence, but also simple physical or temporal succession. The addition of prepositions like syn- or epi- enriches the meaning, creating concepts such as consistency, pursuit, or guidance.
Philosophical Journey
Synépeia, as a concept, traverses Greek thought from the classical period, evolving from a descriptive word into a central philosophical term.
