Cogito, Writing, Techne

To many Philosophers, Descartes is best known as the discoverer of the Cogito, and its immediate application to Medieval proofs of the existence of God.  But, his greatest influence on human society has been his invention of Analytic Geometry, an invention which would be impossible without writing, and without which much of the Quantification of everyday life of the past several centuries would be unthinkable.  The link between his two accomplishments is sometimes under-emphasized by Philosophers--the application of the existence of God to Mathematics, thereby grounding his trust in the latter.  Now, Quantification facilitates control of its matter.  Hence, fully developed, Cogito emerges as Techne, the significance of which tends to be lost on Philosophers who remain insular.  In contrast, a Darwinian might recognize in the connection between Cogito and the written formulas of Analytic Geometry Techne, i. e. the organic relation between Human intelligence and the uniquely Human thumb that grounds most of the Technical developments of the past several centuries.  Regardless, what begins as a Method of Doubt, develops into a Method of Quantification that complements Bacon's Methodology, the fruitful results of which have been abundantly in evidence for centuries.
