Where is development produced? Development is possible only when two entities are in circumstances of reciprocal conditions, and then each becomes a subject. Further, when a subject and object form a new subject the two reach a higher dimension. This is the Principle emphasized by the Unification Church today.

Considering the origin of a being, action is necessary for it come to exist. In order to carry on activities, force is needed. Where does force come from? Force is never generated alone. There needs to be a subject-object relationship. To exist, action is necessary, and for any action, there must be a subject and an object. Without subject and object, no activity is possible.

Even when nations are trying to establish good diplomatic relations, the attempt can be successful only when they pursue a common purpose that would bring both of them progress. The Communist world and democratic world had been continually carrying on a fierce struggle, but in recent years, the stage has been set for their reconciliation. At this moment, as long as they can gain a perspective of purpose that promises progress, the two worlds will certainly be able to unite. But they lack such a perspective.

What do we need here? The world will become one when there is provided the model of a new purpose which, having higher subjectivity, can compensate incomplete objects and have them follow. All beings seek after those who are better than themselves. Why is it that actions are based on pursuits after beings who are better? The Person who is absolute had to use such a Principle during creation in order to bestow reciprocal wholeness before the Absolute Subject. (59-78)

Created entities are divided representations of an entity and are finally synthesized as a greater entity. This is how development occurs. This means that all will enter a realm that is greater. (26-189)

In order to develop into something greater, subject and object must have give and take. Without that, there cannot come into being something greater than that of the present. Therefore, people as well as all things try to form a reciprocal relationships in pursuit of the greater and more valuable. The universe is created in such a way as to enable relationships for continual development. (40-276)
