More than that of Pessoa, Eliot or César Vallejo, Rainer Maria Rilke's poetry has traditionally been considered particularly philosophical. Perhaps, since the publication by Martin Heidegger of the text "For what poets?" (1946), on the occasion of the twentieth anniversary of Rilke's death, this philosophical interpretation has been consolidated. However, neither Rilke is properly a philosopher nor did he ever have a real interest in philosophically systematizing his thought. Despite this, there is no doubt that his poetry has had and still has an enormous impact on the philosophical tradition.

This book is the product of an international meeting held at the Autonomous University of Madrid, on the relationship between Rilke and philosophy. In it are published, for the first time in Spanish, some of Rainer Maria Rilke's own prose texts that we could consider as specifically philosophical, such as the "Marginal Notes on Nietzsche" or the so-called "Letter of the young worker".
