Also when you have microfilms you are in need of some means to be able to interpret those microfilms, You also need some ability to understand things in their real sizes. There is a difference between seeing a small picture of a forest and seeing the forest itself. This is a rather difficult issue which has puzzled many of scientists.

As a matter of fact, when a survey of top scientists, including Nobel laureates, was conducted recently, the vast majority, when asked what will be the most important field of research in the next decade, gave psychobiology as the answer. It is somewhat well understood that neurones in our brains, through sensors, spread out like roots, pulses, electrical signals, if you will, by which they interact with billions of other cells. Brain waves are this measured, charted, and studied.

Yet the nature of information storage is not well understood. The repeated actions of a person, for instance an athlete after intense training which involves repeated motions of the same kind, do indeed leave physical traces in the physiology of the brain; as a stream of water would after running down the same path for a while. This enables the athlete to perform extremely difficult tasks without “thinking” or great effort at co-ordination. Yet this explains only part of the process.

This is the wiring system, so to speak, and not the process of cognition, information storage, and retrieval. In what form the athlete's skills are stored is still not understood. The question occupying many minds is: Is the physical brain the gateway unto something else, or is it all there is, and the end Of all that has to do with cognition? I hope we have understood how to answer this question without being engaged in technical discussions of philosophy.

There are many other ways to prove that knowledge is not material. For example, knowledge is not changeable, but every material. thing is. For instance, today is Saturday. You have the knowledge that you are reading a book on self-knowledge this day. This knowledge is true today. When you think of it tomorrow, it will be the same. Your knowledge about this particular book will be the same after a week, a year, or say even twenty years after.

When you forget something what this really means is that particular data have been lost which cannot be easily retracted tom the memory storage. By no means does it mean that your knowledge has altered. Let us consider another situation.
