Jaoquín M. Fuster, The Neuroscience of Freedom and Creativity: Our Predictive Brain, Cambridge, UK: Cambridge University Press, 2013.
I guess that "exciting" is a relative term since one person's excitement does not constitute another person's ecstasy. If you're interested in neuroscience or the issues of freedom, language, and creativity--this book might be for you. The esteemed Professor Joaquin M. Fuster produces a book that is not written for beginners. Its strength is not accessibility, but the book contains innovative thoughts about the brain and how it relates to our freedom to choose without any prior/antecedent causes.
Fuster does not try to defend a "radical" type of free will. Rather, he apparently wants to contend that our ability to choose between two possibilities (call them A and not A), stems from the nervous system; particularly, from the cerebral cortex. He provides other qualifications on the kind of freedom he has in mind, but Fuster's account differs from other books I've read that allow the hypothetical Laplacean Intelligence to hinder them.
This book appeals to evolutionary developments and organic environments to support the idea that humans can decide between genuine alternatives. Fuster believes that evolution has brought something new into existence by making choice possible. He reasons that one integral factor in our ability to exercise freedom is language. Of course, it's important to understand what Fuster means by language and the relationship that he posits between language and our "predictive brains." This study has given us a lot to consider: it is the product of 50 years spent researching our awe-inspiring brain; one bit of data I am still pondering is how 99 percent of all actions are performed unconsciously. Is it true? And how does that idea affect human freedom?
