three-dimensionality, more than anything else, contradicted the apprehension of the object as a closed material individuality, since perception of three-dimensionality calls for a succession of perceptual elements that have to be combined; in this succession of elements the individuality of the object melts away. On the other hand, dimensions of depth are disclosed only through foreshortening and shadow, so that a vigorous participation of the combinative understanding and of habituation is required for their apprehension. In both cases, therefore, the outcome is a subjective clouding of the objective fact, which the ancient cultural peoples were at pains to avoid.
