Naudé in not a professional philosopher: he works as librarian or sec-
retary and he is an intermediary between the Italian and the French culture.

In France he publishes texts by Nifo, Cardano, Rorario or Campanella. However, he proposes his own original philosophy. In the Syntagma de studio liberali

(1632) he exposes a model of philosophy and of reason that can be defined as a

critical and naturalistic eclecticism. Naudé applies his naturalism and his ration-
al criticism in three directions: historical criticism, political analysis and medical

thought. In the political sphere, he emphasizes the importance of religion as
useful for controlling violent people. In his five Quaestiones iatrophilologicae
(1632-1639) he criticizes every form of determinism – even astrological – in the

name of a medical naturalism flanking materialism and excluding any theological or metaphysical vision.
