It has become somewhat a commonplace in recent political philosophy to remark that all plausible political theories must share at least one fundamental premise, ‘that all humans are one another's equals’. One single concept of ‘basic equality’, therefore, is cast as the common touchstone of all contemporary political thought. This paper argues that this claim is false. Virtually all do indeed say that all humans are ‘equals’ in some basic sense. However, this is not the same sense. There are not (...) one but two concepts of basic equality, and they reflect not a grand unity within political philosophy but a deep and striking division. I call these concepts ‘Equal Worth’ and ‘Equal Authority’. The former means that each individual’s good is of equal moral worth. The latter means that no individual is under the natural authority of anyone else. Whilst these two predicates are not in themselves logically inconsistent, I demonstrate that they are inconsistent foundation stones for political theory. A theory that starts from Equal Worth will find it near impossible to justify Equal Authority. And a theory that starts from Equal Authority will find any fact about the true worth of things, including ourselves, irrelevant to justifying legitimate action. This helps us identify the origin of many of our deepest and seemingly intractable disagreements within political philosophy, and directs our attention to the need for a clear debate about the truth and/or relationship between the two concepts. In short, my call to arms can be summed up in the demand that political philosophers never again be allowed to claim ‘that all human beings are equals’ full stop. They must be clear in what dimension they claim that we are equals—Worth or Authority. (shrink)

Faith in the universal moral equality of people enjoys close to unanimous consensus in present moral and political philosophy. Yet its philosophical justification remains precarious. The search for the basis of equality encounters insurmountable difficulties. Nothing short of a miracle seems required to stabilize universal equality in moral status amidst a vast space of distinctions sprawling between people. The difficulties of stabilizing equality against differentiation are not specific to any particular choice regarding the basis of equality. To show this, I (...) will provide a general diagnosis of the difficulty together with its application to the arguably best attempt at a solution, namely to ground moral equality in a form of subjectivity. In his recent book Equality for Nonegalitarians, George Sher advances the view that “we are moral equals because we are equally centers of consciousness. …The fact that we are equals in this respect—that each is a world unto himself—…explains why each person’s interests are of equal moral importance”. Yet the worlds we are unto ourselves can no more withstand the force of differentiation than previous candidates suggested in the literature, and the reasons why run deeper than even some critics have recognized. The prospects for vindicating universal moral equality remain bleak. (shrink)

There is an apparent problem in identifying a basis for equality. This problem vanishes if what I call the ‘intuited response’ is successful. According to this response, there is no further explanation of the significance of the feature in virtue of which an individual matters, beyond the bare fact that it is the feature in virtue of which an individual matters. I argue against this claim, and conclude that if the problem of identifying a basis for equality is to be (...) resolved, it is necessary to defend a substantive account of the independent significance of some feature.
