You have not graspeda complex unity if all you know about it is how it is one. Youmust also know how it is many, not a many that consists of alot of separate things, but an organized many. If the partswere not organically related, the whole that they composedwould not be one. Strictly speaking, there would be no wholeat all but merely a collection.
This is also an art of putting notes together to make an article or book.
