The writing in From Detached Concern to Empathy is at its best when Halpern draws on clinical vignettes. Indeed, the principal example is a powerful description of a patient left to her own "competent" choice to refuse treatment—an outcome many might call pseudoempathy, or, more harshly, abandonment. But Halpern makes hay with this vignette, as she should. She draws support from writers ranging from Heidegger to Lacan, which requires of readers at least a modicum of philosophical background. Indeed, the middle portions of the book become somewhat dense when Halpern departs from her vignettes. Nonetheless, her criticism of Kant will bring tears to the eyes of the most hardened philosopher. It is hard to argue with someone who advances the theory of one of history's greatest minds.
