We may be like the young boy who loves to take things apart. He is bright enough to disassemble a watch, and maybe even bright enough to get it back together so that it works. But what if he tries to “improve” it? … The boy can understand what is visible, but he cannot understand the precise engineering calculations that determine exactly how strong each spring should be…. Attempts on his part to improve the watch will probably only harm it…. I fear … we, too, do not really understand what makes the [lives] we are tinkering with tick.
