3. Tylor E. B., Primitive culture (Boston, 1874), i, 240–72. Tylor says that counting began with gestures using fingers and toes. At that stage, humans could count no further than four. Later, with the realization that words existed for hands and feet, words for numbers came into being. Still later, it was found that a system based on five (one hand) was scanty, one based on twenty (hands and toes) was cumbersome, and so the base ten was adopted, and so on. At every juncture in the story, Tylor points to a culture, from native Australians and native Americans through Polynesians and native Africans and, of course, up to – and ending – with us.
