I think there are two roots of Western civilization, one in ancient Israel for our spiritual life and the other in ancient Greece for our rational life. The Greeks gave us the program to rise above mere superstition that gave birth to philosophy and science. Sometimes we expect too much from this and need to be reminded that not everything in reality is reachable by purely rational thought. This has been demonstrated several times within science in modern times, and is one of the meanings of Solzhenitzen's statement in today's reading. Ultimate meaning, beauty and truth are concepts and experiences beyond pure rational thought.
