Hermeneutics and ultimate grounding in contemporary philosophy. From its origins deep, philosophical thought has sought the ultimate foundation of human knowledge. Descartes, Kant, Hegel and Husserl, among others, have developed their theories. Given this almost unanimous philosophical interest has emerged in recent decades something really new: it is certain currents of thought that does not just discuss the validity of the various solutions proposed, but more radically question the very legitimacy of the search for the ultimate foundation of knowledge. The author proposes to study the relationship between conception and design hermeneutic foundationalist philosophy.
