Review title: unreliable
Product review: The book has many weaknesses. Descartes' mysticism is not well documented. He suggests that Descartes' work on polyhedrals is motivated by biblical numerology (p. 215), but then a few pages later reverses his claim, and says that Descartes didn't have numerological motivations afterall(pg. 219). He has some interesting information on Descartes and Rosicrucianism, but the question is not throughly explored.Also the book doesn't document its sources well. Its not a scholarly book for that reason. Much of the information/dialogue is based on Aczel's reading of biographer/hagiographer Adrien Baillet. There is reason to question Baillet as a source mainly because he wrote the biography 43 years after Descartes' death. Someone like Rodis-Lewis or Gaukroger wouldn't use Baillet so casually as a source.
