One character I think of — having known a long time — provides an especially poignant example. Long ago I suspected there was something wrong with him. He was “on my side,” but I could never trust him. And this because, he always thought ahead. “He has more brains than he can handle,” I once said of him. A very full head and a rather empty chest. He had no spiritual anchor, no faith beneath his clouds. His principles were mere thoughts: fluff passing over. Even his religious views were “solidly pragmatic,” i.e. easily revised. He could not understand even his own body, because he was all brain. His views were in a constant state of “evolution”: becoming ever more titched.
The head comes loose, when the heart is not screwed in.
