If The Topic Be Highly Abstract, Show Its Nature By Concrete Examples. If It Be Unfamiliar, Trace Some Point Of Analogy In It With The Known. If It Be Inhuman, Make It Figure As Part Of A Story.

Above All Things, Make Sure That It Shall Run Through Certain Inner Changes, Since No Unvarying Object Can Possibly Hold The Mental Field For Long.
