For the modern reader, the expressions "divinatory book" and "questioning the oracle" are likely to elicit a skeptical grin. However, "experimental fact-checking" is one of the mottos of our time. And those who try to apply this principle in relation to the "Book of Changes" will certainly be pretty surprised. For those readers whose rationalism does not allow spending time on such "nonsense," it will still be interesting to get acquainted with this ancient Chinese text, seasoned with German romanticism and ennobled by the meaning of the Russian language.
