The aim of this paper is to bring an end to the interpretative dispute on Descartes’s cog­ito: is the cogitoknown by intuition or by inference? There have been several studies based on both analytical and historical approaches to the dispute, and it seems that we have exhausted all interpretations. Nevertheless, I wish to revisit this dispute, as it ap­pears that the previous studies have overlooked Descartes’s use of words and phrases, which is the most significant for understanding his various discourses on the cogito con­sistently.
