originality of Rosenzweig, Bontas claims, is the exposition of the «rational subjective» approach to substance and knowledge on the «logical form» of the hypothetical thought (i.e., the modal relation of logical consequence between original and non-natural ground and phenomenal consequence, that positively establishes the wholly final and non-ideal destinations of redemption), which valorizes the alliance between pure reason and revelation disrupted by the Kantian epistemology. The title, The Star of Redemption, indicates exactly this long rational and not exclusively mundane «new systematic principle» of coherent and reliable knowledge, which is ultimately shown to be «true» and «right» from a «self-examining» subjective perspective and thereby justified.
