I like that: it has an analytic ring to it! -- and Russell would formality in terms of the theory of relations! Anatole France's paraphrasis is perhaps even more difficult to formalise: "In its majestic equality, the law forbids rich and poor alike to sleep under bridges, beg in the streets, and steal loaves of bread." And Derrida would play with 'different differently', and spell it "differAnt differAntly" As Palma well knows, 'différance' is a term that Derrida coins on the basis of a pun that the French language (but not the English language that Hart writes in -- which was standard English -- he took elocution lessons to drop his Yorkshire accent when working for the chancery -- and he never recovered it!). Derrida's irritating pun is possible because in French the word "différer" can mean either to "differ" or to "defer", depending on context. (Différence can mean to differ from something or to defer something). Apparently, it can all be traced back to Pericles, who never read Derrida in the original. Pericles exclaimed in a funeral oration: "If we look to the laws, they afford equal justice to all in their private differences; if no social standing, advancement in public life falls to reputation for capacity, class considerations not being allowed to interfere with merit; nor again does poverty bar the way". (It was soon adapated by the Romans -- 'equality'; only different. It was Cicero who came up with "æqualitas" (or the shorter "æquitas" in his profuse correspondence) as translating Pericles's important concept. Hart would start alla Kelsen, with analysis. The English abstract noun “equality” translates Gr. isotes, and then Lat. both aequitas, aequalitas. Strictly “Equal,” and “equally” signify a qualitative relationship, so I was not joking when I was referring how Russell would go on formalising this. ‘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. Thus, ‘equality’ needs to thus be STRONGLY distinguished from ‘identity’ (and cf. 'sameness' vs. 'similarity') If Russell was formal, so was Aristotle. Aristotle is first and foremost concerned with formal equality -- expressed as a principle in reference to Plato: “Treat like cases as like” (and cf. the first part of McEvoy's adage: "treating the same the same"). The imperative, "Treat like cases like!" is found in both Aristotle's ethics (Nicomachean Ethics, V.3. 1131a10-b15) and his politics (III.9.1280 a8-15, III. 12. 1282b18-23). In Kant's moral philosophy, it is the categorical imperative formulates the equality postulate of universal human worth. Hart is Kelsenian. "A constitution that says "Every individual is equal before the law" ... may *not* [emphasis Speranza's] be reaching out to a MORAL concept of equality" writes Leslie Green in his Intro to Hart's Concept of Law. Hart is into 'approximative equality': It is , for Hart, what he cals 'approximative equality' which "makes obvious the necessity for a system of mutual forebearance and compromise which is the base of both legal and moral obligation" (The Concept of Law). And note the order, which for Russell is possibly gratuitious (conjunction being commutative): "legal and moral obligation". Hartian order of priorities, no doubt! Not perhaps Hare's or Grice's. When referring to the 'familiar discussion' of 'universalizability', he refers to some sort of very basic manual (with as a tribute to Kant, he calls the IMMANUEL). The manual will have conceptual generality. There will be no way of singling out a special subclass of addressees, and so it enjoy formal generality, too. Finally, applicational generality, as no injunction will prescribe a certain kind of conduct in circumstances in which _any_ addressee would not be likely to be subject.
