We publish here the letters between Gadamer and Ricoeur, as they are found in the Archives of the two philosophers (Gadamer-Archiv in Marbach and Fonds Ricoeur in Paris). Starting from February 1964 and ending on October 2000, the thirty-five letters reproduced here cannot give a complete picture of their much richer correspondence and relations, because it seems that neither Ricoeur, nor Gadamer kept all the letters they received from one another. But altogether, they document their common concerns, their mutual respect, even their intellectual solidarity and finally the particular context that brought them to write to one another, i.e. Ricoeur’s intention to publish a translation of Gadamer’s book, Truth and Method, in a new series he edited for the Seuil Publisher. This publishing and translation project will mark their entire correspondence.
