elops over two periods. The first moment: March 1914, the apparition, as decisive as opaque, of the four heteronymous poets, Alberto Caeiro, Ricardo Reis, Álvaro de Campos, and Fernando Pessoa himself. The second moment: the dramatic intellectual crisis of 1915-1916, during which the idea of the avant-garde and the meditation on the complexity and separation of metaphysics and art willingly battle and entangle themselves. This is a crisis of philosophy Pessoa experiences with anxiety, and which is the origin of the multiple births of the poet. From then on, the task of separating poetry from metaphysics begins. ----about the author Judith Balso has taught seminars on Fernando Pessoa, Wallace Stevens, Pier Paolo Pasolini, Osip Mandelstam, and Dante at the Collège International de Philosophie in Paris, France.
