This lecture proposes a new and developed theory of the dialogical strand in existentialist thought in light of Martin Buber, Franz Rosenzweig and Rabbi Jonathan Sacks. The biblical narrative of the Burning Bush offers a hermeneutic opportunity in the Jewish and dialogical strands of thought, which are rooted in philosophical translations of the words 'I will be what I will be'. This lecture will trace the philosophical interpretations of these thinkers of these words as a test-case for considering the role of the 'transformation' of the individual (based on the Mosaic figure at the theophanic moment) in different religious traditions.
