World-renowned analytic philosophers John McDowell and Robert Brandom, dubbed "Pittsburgh Neo-Hegelians, " recently engaged in an intriguing debate about perception. In "The Intentional Spectrum and Intersubjectivity "Michael D. Barber is the first to bring phenomenology to bear not just on the perspectives of McDowell or Brandom alone, but on their intersection. He argues that McDowell accounts better for the intelligibility of empirical content by defending holistically functioning, reflectively distinguishable sensory and intellectual intentional structures. He reconstructs dimensions implicit in the perception debate, favoring Brandom on knowledge's intersubjective features that converge with the ethical characteristics of intersubjectivity Emmanuel Levinas illuminates.
