“Don Juan had always said to me that our great enemy is the fact that we never believe what is happening to us… when we finally realize what is going on it is usually too late to turn back. He contended that it is always the intellect that fools us, because it receives the message first, but rather than giving it credence and acting on it immediately, it dallies with it instead.”
Carlos Castaneda

The Second Ring of Power

Generative vs. Descriptive

“Does the DNA contain a full description of the organism to which it will give rise? The answer is no. The genome contains instead a program of instructions for making the organism – a generative program …

A descriptive program, like a blueprint or a plan, describes an object in some detail, whereas a generative program describes how to make an object … consider Origami … by folding a piece of paper in various directions, it is quite easy to make a paper hat or a bird from a single sheet. To describe in any detail the final form of the paper with the complex relationships between its parts is really very difficult, and not of much help in explaining how to achieve it. Much more useful and easier to formulate are instructions on how to fold the paper … a generative program for making a particular structure.”
