Barthold’s close reading of Gadamer’s major works enhances our understanding of philosophical hermeneutics in several significant ways. Readers who follow Barthold back to Gadamer’s interpretations of the early Plato will come away with increased clarity about the particular kind of dialectic that persists and pervades Gadamer’s hermeneutics. This focus on the dialectical nature of hermeneutics leads in turn to a deeper insight into the idea of the good that sustains Gadamer’s hermeneutics. Thanks to Barthold, we come to understand that that which makes philosophical hermeneutics dialectical also makes it ethical.
