I made a mistake with this one and listened to the audio book. There was just way too much information to take in while attempting to commute to and from work. Read the book.
The book is basically an attempt to take a look at what we perceive our reality to be. The Matrix is actually referenced quite a bit. The first section, Money, really focuses on the reality that society has set up and the reality that everyone buys in to. That rectangle with Andrew Jackson on it that you exchange for goods? That only means $20 because society has deemed it as such, ergo that is our reality. This was an interesting section mainly because we really do take a lot for granted because we just accept that this reality and the social norms are what we must accept.
Colours is the next section and it's about what we perceive with our senses (Does color exist in the dark?). The we get into Light and some physics that I will admit lost me for a while. Here is where an actual book would have made a lot of difference.
While Baggott does reference the Matrix, this book uses the movie as a jumping off point. The philosophy and physics discussed could lead to some very interesting thoughts and conversations. Again, the audio book was well narrated but not how I should have read this book.
