Flatland by Edwin A. Abbott 1884
What I learned from this 19th century book:
In order to understand an over complex concept (such as 4 D space), try to understand an over simplified concept (such as 2 D world).
The author Edward Abbott is a clergyman, theologian. I think he implied God is in the extra dimension world (4+ D)
This is not a science-fiction; t should be a mathematical fiction.
