Note 105 — PART I PLAYFUL EXPERIMENTATION
Elizabeth L. Baldwin translation
It is otherwise with those born blind. Johann Ruben, who was nineteen when operated on, at once made distance the subject of his investigation. “For example, he pulled off his boot and threw it some distance, and then tried to estimate how far off it was. He walked some steps toward it, and tried to pick it up; finding that he could not reach it he went a little farther, until he finally got it.” Raehlmann, ibid., p. 81.
