John Rawls's magnum opus, A Theory of Justice, is a sweeping rebuke of utilitarianism in all its forms, offering a Kant-inspired social contract theory in its stead.
I have also read Robert Nozick's Anarchy, State, and Utopia
, a critique and counterproposal to Rawls, and am working on my own critique of Rawls's theory, on which I will expound at rawlsian.substack.com
