Jorge Luis Borges is an Argentine poet, essayist, and short story writer. He has written a wide collection of short stories. Growing up he learned English before Spanish, and at the beginning of WWI he and his family moved to Geneva. There he learned German and French, so he was quite intelligent. His writings have become classics of the 20th century.
After reading around 8 of his short stories there seem to be almost more over lapping themes between stories then there are in the actual stories themselves. Borges writes a lot about the universe, and orders; such as tradition, literature, communication, etc. He seems to commonly have a "secret" a story that the reader never seems to find out. He keeps the secret from us as much as it would have been if it was an actual secret. Borges brings up numbers as well, especially in the Library of Babel. The number three shows up quite often as well, it's always three brothers, or three gifts, or three days and three nights. Other than that some themes that occur across his stories are cultures, death, journey, dreams, and more history,
I think I have narrow down my selections to The Library of Babel, The Ethnographer, and The Theologians.
