Why do things not be self-contained units? Like in contemporary times we imagine, say, an album. That album is made up of songs. Is this a recent thing? Sometimes classical music is confusingly organized. Perhaps the apparently "simple" notion of artist - album - track is new. Maybe the terminology has just changed. Same with different media in different cultures. Is that doujinshi a sequel to the previous one? How do I know which to read next? Is this truly as confusing as I'm making it out to be? Of course every person has to make one thing, then the next. That's just logical. Or is it? I don't even know.
