1. Defining the Concept
‘Equality’ is a contested concept: “People who praise it or disparage it disagree about what they are praising or disparaging” (Dworkin 2000, p. 2). Our first task is therefore to provide a clear definition of equality in the face of widespread misconceptions about its meaning as a political idea.
The terms “equality” (Gr. isotes, Lat. aequitas, aequalitas, Fr. égalité, Ger. Gleichheit), “equal,” and “equally” signify a qualitative relationship. ‘Equality’ (or ‘equal’) signifies correspondence between a group of different objects, persons, processes or circumstances that have the same qualities in at least one respect, but not all respects, i.e., regarding one specific feature, with differences in other features. ‘Equality’ needs to thus be distinguished from ‘identity’ — this concept signifying that one and the same object corresponds to itself in all its features: an object that can be referred to through various individual terms, proper names, or descriptions. For the same reason, it needs to be distinguished from ‘similarity’ — the concept of merely approximate correspondence (Dann 1975, p. 997; Menne 1962, p. 44 ff.; Westen 1990, pp. 39, 120). Thus, to say e.g. that men are equal is not to say that they are identical. Equality implies similarity rather than ‘sameness.’
In distinction to numerical identity, a judgment of equality presumes a difference between the things being compared. According to this definition, the notion of ‘complete’ or ‘absolute’ equality is self-contradictory. Two non-identical objects are never completely equal; they are different at least in their spatiotemporal location. If things do not differ they should not be called ‘equal,’ but rather, more precisely, ‘identical,’ as e.g., the morning and evening star. Here usage might vary. Some authors do consider absolute qualitative equality admissible as a borderline concept (Tugendhat & Wolf 1983, p. 170).
‘Equality’ can be used in the very same sense
