Neutrality of what?

In what sense should a liberal state be neutral between the conceptions of the good held by its citizens? Traditionally, liberals have provided two different answers to this question. Some have adopted a conception of neutrality of justification, while others a conception of neutrality of effects. Recently, Alan Patten has defended an alternative, novel and sophisticated, conception of neutrality – neutrality of treatment. In this article I assess whether neutrality of treatment is, in fact, a superior conception of neutrality. I try to show that neutrality of treatment suffers from the very same weaknesses that Patten attributes to its alternatives and that, overall, neutrality of justification, properly construed, provides a more promising account of both the sense in which a state ought to be neutral and of the object of neutrality. Finally, I argue for a broader account of the normative bases of liberal neutrality than the one proposed by Patten. This account includes, beyond considerations of fairness, a relational principle of equal standing.
