and Leiter himself has professed sympathy for Marx, stating in an interview, "On two central issues, Marx was far more right than any of his critics: first, that the long-term tendency of capitalist societies is towards immiseration of the majority (the post-WWII illusion of upward mobility for the 'middle classes' will soon be revealed for the anomaly it was); and second, that capitalist societies produce moral and political ideologies that serve to justify the dominance of the capitalist class."
Philosophical work
Leiter's scholarly writings have been in two main areas—legal philosophy and Continental philosophy—although he has also written about metaethics, religious liberty, and other topics.
Philosophical naturalism has been a major theme in many of these contexts.
Legal philosophy
In legal philosophy, Leiter has offered a reinterpretation of American
Legal Realism as embodying a prescient philosophical naturalism and a defense of what he called "naturalized jurisprudence" in his book ''Naturalizing Jurisprudence: Essays on American Legal Realism and Naturalism in Legal Philosophy'' (Oxford University Press, 2007). Upon publication,
Jeremy Horder wrote that the "book will confirm Brian Leiter's place in the front rank of legal theorists in the world today." Leiter also wrote the entry on "Naturalism in Legal Philosophy" for the ''

''. On his view, "philosophers generally should aim to unpack the 'concepts that have been vindicated by their role in successful explanation and prediction of empirical phenomena'" and thus should "'take seriously the…social scientific literature on law…to see what concept of law figures in the most powerful explanatory and predictive models of legal phenomena such as judicial behavior.' This methodological view, however, raises questions about why the legal philosopher should study only judicial behavior and not something else. More generally, the naturalist owes an account of what features of law are most in need of explication and why."
Continental philosophy
Leiter is also a scholar of

, including an article for the ''Stanford Encyclopedia of Philosophy''. In particular, Leiter defended a reading of Nietzsche as a philosophical naturalist in his ''Nietzsche on Morality'' (London: Routledge, 2002) and in later papers, including one with
Joshua Knobe on "The Case for Nietzschean Moral Psychology" in ''Nietzsche and Morality'' (Oxford University Press, 2007).

Union Council informed the "Nietzsche Club" that it could no longer declare an affiliation with the school because the club was promoting "far-right" and "fascist" ideologies, Leiter first defended the club, saying Nietzsche was not a fascist, but later noted that if the club is a front for a fascist group, then it's a shame that Nietzsche was smeared as a fascist in the discussion.
