Key words: Luis Cernuda, Plato, Presocratic philosophers, Heraclitus, Aristotle, classical tradition, Greek philosophy, Spanish poetry, Spanish Literature

The aim of this article is to show how, although the poet finds himself materialist or both Presocratic and Aristotelian, his poetic emotiveness is truly Platonic or idealist, so that that tension between reality and desire with the help of which his poetry has always been defined becomes once more confirmed thanks to the analysis of his poems from a philosophical rather than a literary point of view.
