Giulio Tononi has written a Dantesque "Divine Comedy" that takes the reader
from Hell to Paradise via Purgatory following not Dante but Galileo
(the father of modern science). In each of the three realms Galileo
is led by a different person, just like Dante in his journey.
The first part, led by a neuroscientist, is a tour of how the brain works.
The second part, led by Alan Turing, explains how
consciousness can arise from the integration of information (what Tononi
The third part, led by Charles Darwin, speculates that
consciousness might still be evolving, just like everything else that is
Along the way Galileo has encounters with Copernicus and Borges that help
clarify issues here and there.
The book has little to offer in terms of groundbreaking theories.
Tononi's "phi" is hardly more than a personal belief. His work with
neuroscientists such as Edelman has not proven much in that direction,
other than the very vague fact that some kind of integration is obviously
important for me to be able to think and operate.
The book is nice to read, but, by the end, there is little one can write about.
Cute idea, though.
