Through mystery, literature reveals to us the Great Unknown. While we are absorbed by the matters at hand with the present enactment of our life, groping for clues to handle them, it is through literature that we discover the hidden strings underlying their networks. Hence our fascination with literature. But there is more. The creative act of the human being, its proper focus, holds the key to the Sezam of life: to the great metaphysical/ontopoietic questions which literature may disclose. First, it leads us to the sublimal grounds of transformation in the human soul, source of the specifically human significance of life (Analecta Husserliana, Volume III, XIX, XXIII, XXVII) Second, it leads us to the unveiling of the hidden workings of life in the twilight of knowing in a dialectic between The Visible and the Invisible, (Volume LXXV, 2002, Analecta Husserliana) down to the ontopoietic truth. (Volume LXXVI, 2002, Analecta Husserliana) This prying into the unknown which provokes the human being as he or she attempts to conquer, step by step, a space of existence, finds its culmination in the phenomenon of mystery as the subject of the present collection. Its formulation brings us to the greatest question of all: the enigmatic solidarity -in-distinctiveness of human cognition and existence. Papers are written by: Tony E.
