 Nonetheless, we would not thereby have achieved everything and certainly not what is most fundamental, simple, and primary…. The living, embodied truth of the three-dimensional space of angles, of form and volume, is not something we can learn through sight. This is all the more true of the essence of sculpture, beautiful form and beautiful shape, for this is not a matter of color, or of the play of proportion and symmetry, or of light and shadow, but of physically present, tangible truth…. Consider the lover of art sunk deep in contemplation who circles restlessly around a sculpture. What would he not do to transform his sight into touch, to make his seeing into a form of touching that feels in the dark…. With his soul he seeks to grasp the image that arose from the arm and the soul of the artist. Now he has it!  The illusion has worked; the sculpture lives and his soul feels that it lives. His soul speaks to it, not as if his soul sees, but as if it touches, as if it feels. (Sculpture, pp. 39–41)
