DESCARTES'S COGITO

Abstract

THIS PAPER PRESENTS THE INTERPRETATION OF DESCARTES'S "COGITO" IN MY BOOK "COGITATIONS" IN A CONCISE AND SLIGHTLY EXTENDED FORM. THE EMPHASIS IS ON CONVEYING THE ESSENTIALS OF THE ARGUMENT THAT "COGITO ERGO SUM" IS AN ANALYTIC ENTAILMENT, BUT I HAVE TAKEN THE OPPORTUNITY TO IMPROVE MY ARGUMENT IN A FEW SMALL WAYS AND TO RELATE THE EXPLICIT FORM OF THE "COGITO" TO SIMILAR REASONING IN DESCARTES'S "SECOND MEDITATION". MY PRIMARY AIM IS TO EXPLAIN HOW THE "COGITO" CAN BOTH BE THE SIMPLE INFERENCE WE FIND IN DESCARTES'S OWN PRESENTATIONS AND YET BE FORMALLY VALID AS IT STANDS.
