Nations, during the successive phases of their evolution on the globe, in which they advance from a State of infancy and barbarism to one of virility and civilization, from civilization to decadence or senility; and from decadence to their final extinction, are liable to numberless calamities. These calamities are produced by moral causes, and are then called social Revolutions; and in other instances from physical causes, and then they are termed Cataclysms, Epidemics, or Epizootics.
