Going Inside

Book review: Going Inside: A Tour Round a Single Moment of Consciousness, by John McCrone.

This book improved my understanding of how various parts of the brain interact, and of how long it takes the brain to process and react to sensory data. But there were many times when I wondered whether it was worth finishing, and I wish I had given up before the last few chapters that focused on consciousness other than neuroscience.

Too much of the book is devoted to attacking naive versions of reductionism and computational models of the brain. His claim that “chaos theory electrified science” is wrong. It electrified some reports about science, but has done little to create better models or testable predictions.

It’s misleading for him to claim the difference between human and animal consciousness “is terribly simple. Animals are locked into the present tense.” There are many hints that animals have some thoughts about the future and past, and it’s hard enough to evaluate those thoughts that we need to be cautious about denying that they think like us. He suggests that language and grammar provide unique abilities to think about the future. But I’m fairly sure I can analyze the future without using language, using mostly visual processing to plan a route I’m going to kayak through some rapids, or to imagine an opponent’s next chess move. I expect animals have some abilities along those lines. Human language must provide some improved ability to think about the future, but I find it hard to specify those abilities.
