Although there are some interesting points made in the text, and I like the concept that the "mark of the cognitive" ought to be made explicit and that cognition ought to have a clearer definition if one is to elaborate and extend the cognition, the book was a little boring and repetitive. I feel like I might have gotten the parts I most enjoyed from reading one of their papers... Overall though, I enjoyed the book and it did provoke questions which I would like to pursue and ponder.
