This brief defense from Commentary is excellent.

An excerpt.

The term itself is not one you often hear from conservatives, perhaps in part because of the brilliant Austrian economist Friedrich Hayek’s distaste for it. Hayek believed the idea of social justice was a mirage, an “empty formula” and “hollow incantation,” and impossible to define. …

On the matter of social justice, Hayek had in mind distributive justice. “There can be no distributive justice where no one distributes,” Hayek put it. “Considerations of justice provide no justification for ‘correcting’ the results of the market,” he said elsewhere. “Only human conduct can be called just and unjust,” Hayek argued. (Hayek himself did not oppose a comprehensive system of social insurance and favored a guaranteed minimum income. His fear was that the concept of social justice would lead to “centrally planned distribution according to merit,” in the words of the philosopher David Schmidtz. “He thinks a merit czar would be intolerable.”)

Professor Hayek’s insights about spontaneous order, the virtues of dispersed decision making, the dangers of collectivism and centralized planning, and the limits of social knowledge are tremendous contributions. But I do think that the term “social justice,” as defined by Hayek, is too constricted and incomplete; that it’s a term conservatives should not only refuse to cede to the left but one they should embrace.

My Ethics and Public Policy Center colleague Yuval Levin reminded me of Irving Kristol’s rejection of Hayek’s denial of the idea of social justice in his 1970 essay “When Virtue Loses All Her Loveliness.” Kristol pointed out that Hayek, for whom Kristol had great respect, preferred a free society to a just society “because, [Hayek] says, while we know what freedom is, we have no generally accepted knowledge of what justice is.”

“Can men live in a free society if they have no reason to believe it is also a just society?” Kristol asked. “I do not think so. My reading of history is that, in the same way as men cannot for long tolerate a sense of spiritual meaninglessness in their individual lives, so they cannot for long accept a society in which power, privilege, and property are not distributed according to some morally meaningful criteria.”
