ΡΗΤΟΣ
Rhetos, a word deeply embedded in Greek thought, signifies that which is spoken, clear, and determined, standing in stark contrast to arrhetos, the unspeakable and ineffable. From everyday discourse to the philosophical distinctions of Plato and the Stoics, and the mathematical definitions of Euclid, the term underscores both the power and the limitations of language and reason. Its lexarithmos, 678, reflects the order and structure that explicit expression seeks to impose on reality.
Definition
According to the Liddell-Scott-Jones Lexicon, ῥητός (adjective) primarily means "said, spoken, expressed," deriving from the verb ἐρέω/λέγω (to say, to speak). Its meaning quickly expanded to encompass anything that is "fixed, appointed, specified" (e.g., a stated price, a fixed deadline) or "clear, explicit, manifest" (e.g., an explicit command). This dimension of clarity and precision made the term central to various fields of ancient Greek thought.
In philosophy, ῥητός gained particular significance in its antithesis to ἄρρητος. Plato, in his Seventh Letter, distinguishes between things that can be spoken or written (τὰ ῥητά) and deeper truths that can only be apprehended through direct experience and spiritual communion (τὰ ἄρρητα). This distinction highlights the limits of verbal expression in approaching ultimate knowledge. The Stoics, in turn, developed the concept of the "lekton" (τὸ λεκτόν), meaning the expressible content of a proposition, which is explicit and can be true or false, as distinct from the word itself or the referent.
In mathematics, particularly in Euclid, the term ῥητός is used to describe magnitudes that are "rational" or "commensurable" (rational), meaning they are commensurable with a given magnitude. For instance, a "rational straight line" is one that is commensurable with a pre-defined straight line, either in length or in square. This usage highlights the precision and quantitative expressibility associated with the term. Thus, ῥητός functions as an indicator of the possibility of expression, definition, and logical understanding across a wide range of cognitive domains.
Etymology
Cognate words include: ῥῆμα (word, verb), ῥήτωρ (orator), ῥητορική (rhetoric), ῥητέον (that which must be said), ἄρρητος (unspeakable), προερῶ (I will say beforehand).
Main Meanings
- Spoken, uttered, expressed — That which has been articulated in words, expressed orally or in writing.
- Stated, specified, explicit — That which has been clearly defined, such as a deadline, a price, or a condition.
- Clear, manifest, unambiguous — That which is distinct, without implication or doubt, precisely formulated.
- (Grammar) Expressed, not implied — In contrast to something understood or implied, the explicit term denotes direct presence.
- (Philosophy) Articulable, rational, intelligible — The aspect of reality or knowledge that is accessible through language and rational thought.
- (Mathematics) Rational number/magnitude — In Euclidean geometry, magnitudes that are commensurable with a given magnitude, i.e., can be expressed as a ratio of integers.
