Michelangelo’s Puzzle

Michelangelo thought that stone statues pre-exist their sculptors’ performance. Michelangelo’s view gives rise to a puzzle, which we call Michelangelo’s puzzle. Michelangelo’s puzzle looks structurally similar to so-called problems of material constitution (e.g., the puzzle of the statue and the clay, or the puzzle of Tibbles the cat); so it is tempting to suppose that it can be similarly accounted for. This paper argues that the supposition is misguided. Michelangelo’s puzzle raises specific problems, which cannot be adequately dealt with unless one is prepared to give up either the natural view that stone sculptures are human creations, or a very plausible principle concerning the persistence of middle-sized material objects. A tentative solution to the puzzle is provided, in which borders can play an ontological role in the making of material objects. This solution is intuitively more palatable than Michelangelo’s view, but is nonetheless at odds with a commonsensical, realist attitude towards material objects. Thus, Michelangelo’s puzzle poses a serious challenge to common sense, which is unparalleled by other problems of material constitution.
