Abstract

This paper tries to draw attention to the epistemological turn that accompanies the birth of modern thought. To this end, the decisive dreams that Descartes experienced at the age of 23 are used as a common thread. These dreams allow us to visualize a progressive transition from oneiric darkness to rational light that is concomitant with a transition from occultism (vigorous in the Renaissance) to rationalism. In this way, it is clarified why, although, as Hegel indicates, there are elements of modern philosophy that are announced in Böhme or in Francis Bacon, this does not find its anchoring point until it reaches Descartes, a point that ties the centrality of the subject to an epistemic turn destined to exile from scientific discourse both the qualitative language of Aristotelianism and the emotive language of Hermeticism.
