Obviously you are looking at this as a coder, not a language designer. There are two purposes (actually only one since those two are one if you can see): 1) Dynamically change or determine the behavior; 2) make it possible for creation of frameworks.

For example, in a GUI program with callback, rendering engine no longer needs to know how to render a component, the component knows and in way renders itself.

This might seem abit diificult for you to understand, but try your best to learn.
