Worst of all, at the theoretical level, Progressivism entirely upended our elite’s understanding of justice, of good and bad. The hidden cause of that upending is the contradiction at the core of Progressivism, which at once denies a fixed human nature and hence a standard of goodness independent of human preference or will but also insists that progress is good. “Historicism”—the belief that values change from era to era—is Progressivism’s indispensable foundation.
