In imagining what the future of our thinking will be like, it’s also interesting to consider how man himself might change how the brain works. We are certainly doing that with drugs and technology. Given advances in genetic engineering, it’s reasonable to expect that someday genetic engineers might mix and match features of different species’ brains for different purposes—if you want to have a heightened sense of sight, say, genetic engineers might be able to manipulate the human brain so it grows optic lobes more like those of birds. But since such things won’t happen anytime soon, let’s get back to the practical question of how all this can help us better deal with ourselves and each other.
Understand the great brain battles and how to control them to get what “you” want.

The following sections explore the different ways your brain fights for control of “you.” While I will refer to the specific parts of the brain that neurophysiologists believe are responsible for specific types of thinking and emotions, the actual physiology is much more complex—and scientists are only beginning to understand it.

Realize that the conscious mind is in a battle with the subconscious mind. Earlier in the book, I introduced the concept of the “two yous” and explained how your higher-level you can look down on your lower-level you to make sure that your lower-level you isn’t sabotaging what your higher-level you wants. Though I’ve often seen these two yous in action in myself and others, it wasn’t until I learned why they exist that I really understood them.
