Alternatively, you could check out his non-fiction, say Selected Non-Fictions (https://www.amazon.com/Borges-Selected-Non-Fictions-Jorge-Lu...). Checking the table of contents, I particularly like "A New Refutation of Time" (Available from Gwern: https://www.gwern.net/docs/borges/1947-borges-anewrefutation...), "Pascal's Sphere" (also available: https://www.gwern.net/docs/borges/1951-borges-pascalssphere....), and the lecture "Blindness" (https://www.gwern.net/docs/borges/1977-borges-blindness.pdf; there may be some copyright issues here).
