Abstract

Many scholars have suggested that Aristotle’s famous aphorism ‘treat equals equally, unequals unequally’ is a formal, and thus impractical, theory of equality. This dissertation aims to criticise the popular view that Aristotle’s theory of equality is purely formal and to develop and defend an interpretation which will pay attention to the substantive elements. The first chapter argues that Aristotle provides us with a spectrum from formal to substantive equality. At the formal end, we have the abstract principles of formal fairness and proportionality, while at the substantive end we can find information for the designation of the appropriate variable of comparison between people or treatments in various domains of social interaction. The second chapter argues for an account of commensurability based on Ph. VII.4. I claim that, in any comparison, the term ‘equal’ should be predicated synonymously of the people or treatment compared, while at the same time they should not admit to difference in species; such an account, I suggest, is also compatible with Aristotle’s theory of economic value in EN V.5. The third chapter presents the Aristotelian account of equality in distributions. I focus on Aristotle’s theory of political distribution in Pol. III, where he puts forward two distinct criteria: political capacity and contribution to the polis. I also examine Aristotle’s moderate suggestion for equalisation of property by the means of public property and taxation. The fourth chapter criticises the popular line that Aristotle holds an inconsistent theory of corrective justice, because in EN V.4 he suggests that people should be treated as equal before the law, while in the first lines of EN V.5 he allows for hierarchical considerations. I eliminate this apparent inconsistency by claiming that the former deals with the compensatory, while the latter with the punitive element of corrective justice. The fifth chapter explores the role of equality within the private domain, mainly in the household and in various types of friendship. I propose that Aristotle offers two types of superiority, one based on actuality and a second based on function, which are not mutually exclusive. To summarise, by examining Aristotle’s responses to various problems about equality and hierarchy I conclude that although he possesses the theoretical tools to argue for ‘inalienable’ metaphysical equality of human beings which will make equality an individual entitlement or right, based on his principle of individuation in Metaph. Z.8, he prefers not to utilise this thesis for political purposes. Instead, he reduces equality to justice (inequality is unjust, since it violates principle of formal fairness which is fundamental for justice) and a set of pragmatical considerations (e.g. concord and the optimal outcome for the polis). He prefers to argue that equality or hierarchy of people or treatments is related to, and defined by, the particular institution that we examine.
