There is little doubt about the fact that the twentieth century will be seen as an extraordinary paradox. On the one hand, it has been a century marked by a veritable explosion in information and in tremendously complex technology, but on the other hand, it has been a century marked by profound ignorance. The amount of wealth that has been spent on new and creative ways to kill and destroy is almost beyond measurement. The six million Jews who died in Germany have left an indelible mark on the entire century. The nuclear arms race is now widely viewed as the madness that it was. The extent to which people have permitted the unfettered exploitation of nature has rendered extended human existence on the planet a debatable proposition. The consolidation and control of the global food supply by a handful of multinational corporations represents an example of ignorance of the most profound sort.
