The author holds that the old theory according to which philosophy is the matrix of argumentation studies must be entirely reviewed currently. He argues that argumentation theory, as an interdisciplinary domain, may start playing, in new terms, the role which ― in the Cartesian tree ― was that of philosophy as the trunk of the different branches of human knowledge, as long as a set of requirements, which he lists, were met.

The author- following his own research on the subject- argues that Wittgenstein ignores argumentation theory and in general, the problems of rhetoric and argumentation. From this point of view, he frames Stephen Toulmin’s reading of Wittgenstein, arguing that the British philosopher- who was a student of the Austrian- advocates precisely the same thesis. He explains that this happens in a very peculiar (rhetorical) context on Toulmin’s part; a context in which, in essence, Wittgenstein’s philosophy is being rehabilitated.
