Antonio Damasio's error

Antonio Damasio writes that Descartes's error (this is the title of his book) is that first we are, (we have a body, we are biological beings) and only then we think. According to Damasio, Descartes error was also that he thought he could radically separate mind from body.

But Descartes was very cautious, more than Damasio. Descartes--as we can see thanks to the reading line by line by Marcial Gueroult--believed that

"La connaissance de mon existence ne pouvant être que strictement intellectuelle, il en résulte que ma nature ne peut être conçue que comme pure intelligence et, par conséquence, comme pur esprit." (Marcial Gueroult, "Descartes selon l'ordre des raisons", t 1, p. 65).

Damasio's error : we cannot point to an Error in Descartes without speaking to him.

Because Descartes posed by his own words --as Lacan precisely says--"cogito sum". Descartes perhaps forgot he first of all-- said. Descartes had to say this.

So, in the same line, only speaking with Descartes it would be possible to "knot" Descartes's error.
