Chapter 1 of A Mentoring Course on Smalltalk
# Preliminaries
This book begins with a discussion on a quite abstract subject: some of the peculiar characteristics of how we perceive. With these details in mind, it will be much easier to arrive at powerful generalizations later on. In addition, many things that are usually considered self-evident will be clearly seen as consequences of much simpler and more profound principles.
The act of seeing things is such a common state of affairs that it is usually assumed to be obvious, even axiomatic. Because we take this feature of our lives for granted, we seldom question the mechanism that makes it happen. But much waits to be understood behind this apparently intractable phenomenon.
