As Yogi Berra once said, predictions are very difficult, particularly ones about the future. The difficulty of predicting the future has not stopped many people from trying their hand at crystal-ball gazing: from stock picking, to sport betting, to weather predictions, and astrology, seeing into the future has continued to mesmerize the mind. If only it were real. The 16th century French diviner, Nostradamus, is widely considered the most famous prophet — outside of the Bible — who ever lived, even though he never considered himself a prophet. In his new book, Nostradamus: The Complete Prophecies for the Future, this week’s guest, Mario Reading, (who himself was raised in the birthplace of Nostradamus), presents an original and thought-provoking interpretation of the famous quatrains of Nostradamus. Along the way, Mario gives Nostradamus’s prediction of the next U.S. president and also conveys a message of hope: Nostradamus may have seen into the future, but in his heart he believed the future was ours to change.
