The ways in which societies change and adjust to change are determined largely by cultural and historical factors, by long-standing customs and traditions. Cultural values differ widely from one society to another; each solves its problems according to its own values, and value systems, though they may work well for one society, cannot be expected to work as well for another. This is true even of colonies that become independent nations, although the characteristic stamp of the common mother country remains visible. What is unique in the case of Spanish America is the inability of the new nations to shed this stamp, despite determined efforts to do so. To understand the process of change of any country or group of related countries such as those of Spanish America, it is necessary to examine the major cultural characteristics and values, and to consider social and political action in relation to these, rather than to any external standard.
