The Act of Love promotes a philosophical revival of Buber’s dialogical thought by repositioning it as a philosophy of action, departing from a long-established consensus that narrowly viewed it as a post-Kantian epistemology. Based on careful analysis of his writings, the book’s main thrust is to reconstruct Buber’s argument that dialogue is the perfected form of action, and a perfect action is necessarily dialogical. This reconstruction renders Buber's dialogical thought pertinent to contemporary analytic philosophy by situating it within central discussions in the field of philosophy of action.
