But, Foley, my lad, it isn't beauty per se that makes wire-walking Zen or makes it art. It's the extremity of the risks that are assumed by each exquisite gesture, each impossible somersault. Here's a more extreme version of the dangerous beauty bullfights used to possess before the matadors became preening cowards and stacked the desk against the beasts. We only rise above mediocrity when there's something at stake, and I mean something more consequential than money or reputation. The great value of a high-wire act is that it has no practical value. The fact that so much skill and effort and courage can be directed into something so ostensibly useless is what makes it useful. That's what affords it the power to lift us out of context and carry us-elsewhere.
