Introduction of Cartesianism into logics:: The 'Logica Vetus & Nova' by Johannes!Clauberg.

The Logica vetus & nova published by Johannes Clauberg (1654) is directly inspired by the works of Descartes. For this reason, this text is commonly considered as the first handbook of << cartesian >> logic. Which are, therefore, the Cartesian elements distinguishing this logic from the previous ones ? Our aint is to show that there are two main aspects which Clauberg derives front the works of Descartes : oil the one hand the foundation of logic oil the perceptio clara et distincta; oil the other the role of medicina mentis assumed by logic, on the basis of a philosophical theory of prejudices that has been derived from the Principia philosophiae (but also from Bacon). Clauberg's logic, anyway, does not accept the most radical innovations of Cartesian theory of knowledge : in this way it is still bound tip with the scholastic tradition.
