Only the Absolute Being is infinite. For the universe was created by God and it is headed for purpose and develops by the autonomy of the Principle itself. He regarded also cognition and thinking as activity. He said that man's essence is activity, since everyone recognizes, thinks, and acts, i.e., he is always in activity. But from the viewpoint of Unification Thought it is wrong to include cognition in the category of activity.
Cognition is made for obtaining joy, whereas activity is made for the dominion over all things.
Also it is erroneous to say that self and non-self are contradictory to each other. If man had not fallen, man would have dominated all things by love. There could be neither struggle nor contradiction between man and all things, but only harmony between them. Contradiction is the relationship of mutual negation between the two. Thus, there can be no mutual negation.
