In Japan it was once customary to give young people about to be married a "pillow book." This was a small volume of wood-block prints, often colored, showing all the details of sexual intercourse. It wasn't just that, as the Chinese say, "one picture is worth ten thousand words." It was also that it spared parents the embarrassment of explaining these intimate matters face-to-face. But today in the West you can get such information at any newsstand. Sex is no longer a serious taboo. Teenagers sometimes know more about it than adults.
The standard-brand religions, whether Jewish, Christian, Mohammedan, Hindu, or Buddhist, are—as now practiced—like exhausted mines: very hard to dig. With some exceptions not too easily found, their ideas about man and the world, their imagery, their rites, and their notions of the good life don't seem to fit in with the universe as we now know it, or with a human world that is changing so rapidly that much of what one learns in school is already obsolete on graduation day.
