Of gods and germs

When the Black Death visited Norway in the 14th century, it may have wiped out half the population of that country. This staggering tribulation was, of course, considered an act of God. We now know it was caused by the bacterium Yersinia pestis, which was doing what all living things must do -- trying to make a living. See this week's Musing.
