Let us look at Michelangelo’s Moses (Fig.l) to understand how the hand, head, and heart work in concert in art. Imagine the manual skill of stone carvers, who chisel, abrade, and polish in order to fashion illusions of flesh, drapery, and hair from material that is very much unlike any of these. Consider the vast intellectual grasp of the weight of human history, of anatomy, and of geometry that is required to wring such meaning and form from marble. And reflect on the emotion that must be invested in works that are so expressive of emotion.
