This book is about attribute mathematics, in which nothing ever gets bigger or smaller. More specifically, it is about some of what attribute mathematics can do toward the full digitalization of thought and language. The matter is relevant not only directly to linguistics and philosophy but also indirectly to electrical engineering and neuroscience. The twenty-first century will be that of the brain. Human existence will gradually be turned inside out as tools such as genetics and Boolean algebra allow us to see ourselves function on the smallest scale while it is happening.
