“Man knows himself as body, and what he knows of spirit comes through grace. The poet would call it inspiration. But the spirit bloweth where it listeth. Man has no control over his inspiration. If a piece of music or a poem has moved him once, he can never be certain that it will happen again. But man hates to think that he has no control over the spirit. It would discourage him too much. He likes to believe that he can summon the spirit by some ordinary act. Instead of striving to prepare himself for it through discipline and prayer, he tries to summon it arbitrarily through some physical act—drinking Düsseldorf beer, for instance. . . Stein said, chuckling:Which is the way all good Düsseldorfers summon the spirit, since our Dunkelbier is the best in Germany. The priest laughed with him, and for a moment Sorme had a curious impression that he was listening to an argument between two undergraduates instead of two men in their late sixties. He shrank deeper into his armchair, wanting them to forget his presence. The priest stopped laughing first, and Sorme had a glimpse of the tiredness that always lay behind his eyes. Stein also became grave again. He said: Very well. But what has this to do with the murderer? It has to do with sex. For sex is the favourite human device for summoning the spirit. And since it is also God's gift of procreation, it nearly always works. . . unlike music and poetry. Or beer, Stein said. Quite. But even sex is not infallible. And man hates to think that he has no power over the spirit. The more his physical methods fail him, the more voraciously he pursues them. His attempts to summon the spirit become more and more frenzied. If he is a drinker, he drinks more, until he has more alcohol than blood in his veins. If he is a sensualist, he invents sexual perversions. Ah, Stein said. There are many other ways, of course—the lust for money and power, for instance. All depend upon man's refusal to face the fact that the spirit bloweth where it listeth, that no physical act can be guaranteed to summon it. . .”
