In his epistemological work in the "Discourse on the Method", he had realized that, although he could doubt that he possessed a body, he could not under any circumstances doubt that he possessed a mind, which led him to conclude that the mind and the body were two very different and separate things.

Most famously, this is known as cogito ergo sum Latin: "I think, therefore I am"or more aptly, "Dubito, ergo cogito, ergo sum" Latin: "I doubt, therefore I think, therefore I am". There he gambled, rode, fenced, and went to the court, concerts, and the theatre.

First, notice that metaphysics constitutes the roots securing the rest of the tree. Generosity requires a resolute conviction to use free will correctly, while the second maxim is a resolution to stick to the judgment most likely to lead to a good action absent a significant reason for changing course.
