The transformation from one state to another does not occur suddenly. Rather, there is continuous mutation similar to the process of evolutionary development in living creatures. Social order is never perfectly still: it is in perpetual motion. But metamorphosis can occur at different speeds. It can be observed in ancient times in Sparta as well as in Athens, and in modern times in China as well as in England. The difference is that change can occur at a slow pace as in Sparta or China, or motion can proceed quickly as in Athens or England. Moreover, such differences can characterize the same country at different points in time. For instance, Italy has experienced perpetual motion from the legendary times of Romulus until the present, but the process of change is more intense some years than others. It is easy to understand how people mark the dawn of a new age.
