Specialized Knowledge

This chapter talks about the two types of knowledge, general and specialized, and obviously (given the title of the chapter) emphasises that specialized is better than general knowledge. A comforting thought to all of us who aren't very good at trivial pursuits.

Specialized knowledge involves playing to your strengths. It involves identifying an area of knowledge or skill, which you can use to your advantage. And the key word is "use":

"Knowledge is only potential power. It becomes power only when, and if, it is organized into definite plans of action, and directed to a definite end."

But the reassuring point about knowledge that this chapter makes is that you don't necessarily need to spend the rest of your life in a library or the inside of a university lecture hall to get knowledge. In fact, you don't need to have the knowledge in your own mind. You just need to have access to the knowledge. Henry Ford had an office with a row of "electric push-buttons" to summon to his aid any man who had the knowledge he was seeking. Today we call this a cell phone, but the message is the same. As long as you know where and how to find the knowledge it is as good as cramming it into your mind.
