Martin Heidegger’s understanding of art and Paul Ricoeur’s reading of the poetics of existence, developed through his hermeneutics of symbols, metaphor and narrative, open an immense vista to a theological thinking that desires to place primacy on the hearing of the symbolic language of poetry and literature. Beginning a few decades ago, various theologians have ventured along this trajectory, but theology still remains under the dominion of “theoria” and “praxis” and is not very open to “poiesis”. The study presented here (...) revisits the book of J.-P. Manigne on the Poetics of Faith from the 1970s, and the doctoral thesis of A. Thomasset on the Poetics of Morality, from the 1990s, showing how poetic reason provoked theological discourse in the second half of the 20th century. It is part of a research still in progress, devoted to other contributions of the beginning of the 21st century. (shrink)
