Jorge Luis Borges dedicates a poem to Descartes titled 'Descartes' which is integrated into the poetry collection La xifra (1981), and in which he adopts the poetic voice of the philosopher himself and poetically meditates on dreams, the symbolic representation of Cartesian doubt, methodical doubt, and the metaphysical and epistemological consequences, as it affects both existence itself and the nature of reality, as well as the rational capacity to know the world. The poem also includes more vital verses, in which he disorderly reviews some events of his life.

Jorge Luis Borges shows his admiration for Spinoza's philosophy, dedicating two complete poems to him, entitled 'Spinoza'. The first is included in the collection The Other, the Same (1964), and the second in The Iron Coin (1976).
