Is Henry Corbin a philosopher? According to our research, we are obliged to answer in the affirmative, as he says of himself:"Indeed, I am not nor a germanist, not even an orientalist but a philosopher pursuing his quest wherever the spirit guides him." But how can one understand and categorize a philosopher whose quest is guided by the spirit? Henry Corbin has developed what we must call a"prophetic philosophy," and by exploring his biography and youthful influences, namely Heidegger and Hamann, we can lay the foundation of its phenomenologico-hermeneutical method. This research ends with the exploration of the space (imaginal world) and of the organ of knowledge (active imagination) which make us pay attention to the prophetic philosophy of Henry Corbin: a world in which the theophany, the mystical epics, and the visions of mystics and theosophists come about.
