Man, having started his life in the body and not in the mind, experiences work and life. Body is not conscious and is subconscious. It learns by doing. Learning succeeds doing. This is also so because existence and survival compel man to act and to do. He has to eat, drink and sleep. His act of eating over the centuries makes him learn how to gather food more efficiently. The compelling need of thirst sets him in quest of water. He cannot wait to learn about food and drink. Long practical experience leads to knowledge of the process. That is true till now. The cities man has built, the religion he soared to, the science he has discovered and all he has achieved today are achievements in experience, not experiences that issued out of knowledge.
A few thousand years of man’s existence which is studded with rich experiences have not led him to know the knowledge-basis of those experiences. Medical theory is of recent origin. No theory of history is yet born. Science is striving its best to found itself on a theory. As for social development, we do not have any indications of thinkers trying to evolve a theory. Hundreds of theories have been discovered and have gained social acceptance, but they are of partial phenomena, rather a particular phenomenon. There seems to be no theory or even an attempt at it.
