Some psychologists define education as readiness for achievement of the truth and undertaking responsibility in the future life.

While others have introduced education as manifestation of talents and realization of internal powers.

Some others, like John Dioei, the famous psychologist, have assumed education as revision in the experiences of the past and their re-formation for making the experiences more meaningful, and making the individual ready for guidance in the future experiences.(1)

We believe that the above triple definitions may refer to one reality, and in fact the third definition is the principle of that reality, and the first is its introduction and the second is its result.

Furthermore, for clarification of the third definition, it should be explained that a man performs two types of actions:

1- Educational actions

2- Regular, aimless and non-educational actions In the second type, one either do not know the quality of cause and effect relations at all, or does not know its limits, just as one does not know how to turn on a lamp or a factory, and puts his finger on the key without information and previous experience. But after perceiving this cause and effect relation, and revising in his previous experiences, and reforming them, this action will be educational for finding a broader sense and meaning and making him ready for the future, and consequently he refers to the key for turning on a lamp without being wandered.
