Foucault, Les mots et les choses

I just finished This book, possibly the last of Foucault's that I haven't yet read. He is resting his entire analysis of semiotics on the notice that, at the end of the XVIIIth century, the fields of knowledge that required synthesis became separate from the fields of knowledge that required analysis. In other words, social sciences became separate from the exact sciences. I have two comments about that. First, this is only one phase of a much broader phenomenon of the rise of scientism which has been chronicled and discussed at length by other French philosophers before Foucault. Second, I also noticed an epistemic revolution with the Aristotlelian revival about a century earlier, the consequences of which we are still experiencing.
