Experimental Reason and Archimedes' Lever

Galileo, Copernicus, Newton, and Einstein are among the scientists usually cited as inspiring Modern Philosophy.  However, the most influential of all might be an Ancient scientist--Archimedes.  For, the acknowledged 'father' of Modern Philosophy, Descartes, in the Second Meditation, explicitly acknowledges the 'Archimedean Point' as exemplary for his quest for Certainty, characterizing that point as "firm and unmovable".  However, that characterization betrays both its own shortcoming, and that of the aspects of the Cartesian system that are modeled upon it.  The Archimedean Point may indeed be firm and unmoveable, but without the Lever of Archimedes' image, it is inert, as well,  Likewise, Descartes' 'I think' is, in itself, only an isolated point with no motive power.  On the other hand, a few years later, in the Passions of the Soul, he seems to discover his psychic Archimedean Lever--the pineal gland, in which "slight movements . . . may greatly alter the course" of behavior.  Furthermore, the most fundamental of these passions, according to him, is Wonder, which, as, has been previously discussed here, is the initial stage of Experimental Reason.  In other words, Experimental Reason is the Archimedean Lever of the Cartesian Soul, from which the 'I think' is an abstraction', and, hence, of the ensuing Philosophical tradition.
