ΣΥΝΝΟΙΑ
Synnoia, a compound word from "syn" (together) and "nous" (mind, thought), describes "concurrence of thought," "understanding," or "conception." In ancient Greek philosophy, especially among the Stoics, it gains particular significance as a "natural conception" or "conscience." Its lexarithmos (781) suggests a deep spiritual and cognitive dimension, connecting it with wisdom and inner enlightenment.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, synnoia originally means "concurrence of thought, agreement in thought." The word, derived from the prefix syn- (together, jointly) and the noun nous (mind, thought, intellect), denotes a meeting or coincidence of meanings and ideas. This basic sense quickly expands into more abstract and philosophical applications.
In Plato, synnoia can refer to understanding or apprehension, the mind's capacity to grasp concepts. However, it is among the Stoic philosophers that synnoia attains its most prominent position. For them, synnoia is not merely a thought, but a "natural conception" (κοινὴ ἔννοια), an innate idea or preconception existing in the human mind, essential for understanding the world and developing reason. These natural conceptions were considered fundamental to their ethics and epistemology.
Furthermore, synnoia can acquire the meaning of "conscience," i.e., the inner knowledge of right and wrong, or "internal reflection" and "consideration." This ethical dimension is particularly evident in later authors, where synnoia is linked to self-knowledge and moral self-criticism. The variety of its meanings highlights its central place in ancient Greek thought concerning mind, knowledge, and ethics.
Etymology
The family of words derived from the root nous and its compounds with the prefix syn- is rich and significant. It includes verbs such as noeō ("to think," "to perceive," "to understand"), nouns such as noēma ("thought," "concept," "meaning"), and noētos ("perceptible by the mind"). The prefix syn- also combines with other verbs and nouns to denote the concept of coexistence or cooperation, as in synnoeō ("to think together") and synnoos ("of the same mind").
