ΙΣΟΣ
The word ἴσος (isos) represents a fundamental concept in Greek civilization, expressing equality, balance, and proportion across diverse fields: from geometry and mathematics to philosophy, law, and ethics. Its lexarithmos (480) underscores this harmony, as 4 symbolizes stability and 8 completeness, while the sum of its digits (4+8+0=12, 1+2=3) alludes to triadic unity and perfect equilibrium.
Definition
According to the Liddell-Scott-Jones Lexicon, ἴσος (isos) is an adjective meaning "equal, like, the same, fair." Its meaning extends from simple quantitative or qualitative equality to ethical and political isonomia. In classical Greek thought, ἴσος is not limited to numerical identity but encompasses the concept of proportion, symmetry, and justice.
In philosophy, Plato and Aristotle extensively examine the concept of equality. Plato, in "Gorgias" (508a), refers to "geometric equality" (ἰσότης γεωμετρική) as the principle of just distribution, in contrast to arithmetic equality which can lead to injustice if individual differences are not considered. Aristotle, in "Nicomachean Ethics" (V.3, 1131a-b), distinguishes "distributive justice" (διανεμητικὴ δικαιοσύνη) based on proportional equality (κατ' ἀξίαν) from "corrective" or "rectificatory justice" (διορθωτικὴ/ἐπανορθωτικὴ δικαιοσύνη) which aims for arithmetic equality in redressing wrongs.
In mathematics, the concept of ἴσος is fundamental, as evidenced in Euclid's "Elements," where equality is precisely defined for geometric figures and magnitudes. ἰσότης (isotēs) is a prerequisite for proving theorems and constructing figures. In politics, "isonomia" (equality before the law) was a central principle of Athenian democracy, implying that all citizens had equal rights and obligations, regardless of wealth or social status.
