3.5 stars. This is one of the books I should have read long time about. It walks between adventurous theories of cognitive philosophy and unscientific new age bullshit. While the main premise of the book is unorthodox but reasonable, a good part of the book is spent in straw man fallacies and unprovable beliefs.
There are a couple of important ideas here: cognition in human beings are formed by multiple components, however we feel as one unit. As such, symbolic models don't offer an accurate view of human cognition, and even more, they authors claim, there is no representation whatsoever. Cognition is not a process that occurs (only) in brain, but it is a process the involves the organism's body (and the environment, proponents of the extended mind would say). I think there is some truth on this version, but symbols do exist in cognitive systems, maybe at a much higher level, but they can't be dismissed completely. Another important discussion is about the existence of the _self_. Regardless of the opinion of the authors, it seems to me the existence of the ego-self is validated by some evolutionary advantage as to not having one, despite all the philosofical acrobacies used to prove otherwise.
One red flag for me is the use of Buddhism meditation and midfulness as a way to explain natural phenomena. It is common for some western scientist to look at eastern philosophies and assume they have everything figured out, simply because they look mysterious and ancient. Maybe they do, but for me this is a mild version of orientalism. Overall, the argument is that we need to expand cognitive science methods and include the individual experience in our analysis. While I completely agree in principle, I don't think that this should become a free pass for any method of analysis without some minimum of rigour: just because **I** feel this way, doesn't mean eveyrbody does (hence it is not cognitively generalizable), especially when the authors come from W.E.I.R.D. societies. The classic counterargument for this refutation is that standard scientific practice is not open minded enough, but we already have a huge problem with replicability with existing structured and formal methodologies; we don't need more noise over the already existing one.
Another red flag is the dismissal of the pre-given world: I'm not sure the extent of this claim, do the authors really refer to the whole natural universe (13Ga old) or only when humans are involved? Regardless, it seems pretty confusing to me.
Regarding the opinions on evolution, the authors try to prove wrong a version of natural selection and adaptation that nobody is actually claiming exists. It is true you can't track the specific advantages or progress made by one particular gene, being pleitropy only one of the factors involved. But we can't measure the position of a specific molecule of gas in a container and that doesn't invalidate statistical mechanics, so there is no problem with that. Additionally, nobody is claiming there is no mutual relationships between organism and environment, co-evolution, extended phenotypes and other mutual interactions have been part of standard evolutionary theory for years.
The final chapter ends adding a bunch of commentaries regarding morality ethics, global thinking, etc. I think those are topics way above the level of what is and how cognition works, and it feels more like propaganda than
actual science. Some examples:
> (If the reader thinks that Nagarjuna’s argument is a linguistic one, that is because he has not seen the force of the Abhidharma.)
or
> As the student goes on, however, and his mind relaxes further into awareness, a sense of warmth and inclusiveness dawns.
Overall, I think this is a very brave book that present unorthodox ideas. While many of them are wrongly justified, I think the main concepts of embodied cognition is probably true. As a final thought, I would love to know Varela's opinion given the recent criticism on mindfulness and the explosion of connectivist deep learning models that are being deployed nowadays.
