 In his account, Cheselden noted that when the boy—who recently has been identified as Daniel Dolins—was first able to see, he did not know the shape of a thing and could not recognize one thing from another, regardless of how different in shape or magnitude they  were.[2]  Some philosophers thought that Cheselden’s observations were unequivocal and that they confirmed the hypothesis that a blind man restored to sight would not be able to distinguish objects and would have to learn to see. Most of these philosophers, we might mention Voltaire, Camper and the elder Condillac as examples, were adherents of Berkeley’s theory of vision, which had predicted a similar outcome.
