Borges: I know very little about it. I was told of the Pampas Indians by my grandmother. She lived all of her life in Junin; that was on the western end of civilization. She told me as a fact that their arithmetic went thus. She held up a hand and said, “I’ll teach you the Pampas Indians’ mathematics.” “I won’t understand,.” “Yes,” she said, “you will. Look at my hands: 1, 2, 3, 4, Many.” So, infinity went on her thumb.
