"We find in the story of the Sand-Man the other theme on which Jentsch lays stress, of a doll which appears to be alive. Jentsch believes that a particularly favourable condition for awakening uncanny feelings is created when there is intellectual uncertainty whether an object is alive or not, and when an inanimate object becomes too much like an animate one. Now, dolls are of course rather closely connected with childhood life. We remember that in their early games children do not distinguish at all sharply between living and inanimate objects, and that they are especially fond of treating their dolls like live people. In fact, I have occasionally heard a woman patient declare that even at the age of eight she had still been convinced that her dolls would be certain to come to life if she were to look at them in a particular, extremely concentrated, way. So that here, too, it is not difficult to discover a factor from childhood. But, curiously enough, while the Sand-Man story deals with the arousing of an early childhood fear, the idea of a ‘living doll’ excites no fear at all; children have no fear of their dolls coming to life, they may even desire it. The source of uncanny feelings would not, therefore, be an infantile fear in this case, but rather an infantile wish or even merely an infantile belief. There seems to be a contradiction here; but perhaps it is only a complication, which may be helpful to us later on."
