I strongly agree that great achievements often lead to great discontent. In fact, I would assert more specifically that great individual achievements can cause discontent for the individual achiever or for the society impacted by the achievement, or both. Neverthe- less, it is important to acknowledge that whether a great achievement causes great dis- content can depend on one's personal perspective, as well as the perspective of time.
With respect to individual achievements, great achievers are by nature ambitious people and therefore tend to be dissatisfied and discontent with their accomplishments—no matter how great. Great athletes are compelled to try to better their record-breaking per- formances; great artists and musicians typically daim that their greatest work will be their next one--a sign of personal discontent. And many child prot6g6s, especially those who achieve some measure of fame early in life, later suffer psychological discontent for having "peaked" so early. Perhaps the paradigmatic modern example of a great achiever's discontent was Einstein, whose theoretical breakthroughs in physics only raised new theoretical conundrums which Einstein himself recognized and spent the last twenty years of his life struggling unsuccessfully to solve.
Individual achievements can often result in discontent on a societal level. The great achievement of the individual scientists responsible for the success of the Manhattan Project resulted in worldwide anxiety over the threat of nuclear annihilation-- a form of discontent with which the world's denizens will forever be forced to cope. Even individual achievements that at first glance would appear to have benefited society turn out to be causes of great discontent. Consider the invention of the automobile, along with the innovations in manufacturing processes and materials that made mass production possible. As a result we have become a
society enslaved to our cars, relying on them as crutches not only for transportation but also for affording us a false sense of socioeconomic status. Moreover, the development of assembly-line manufacturing has served to alienate workers from their work, which many psychologists agree causes a great deal of personal discontent.
Turning from individual achievements to societal, induding political, achievements, the extent to which great achievements have caused great discontent often depends on one's perspective. Consider, for example, America's spirit of Manifest Destiny during the 19th Century, or British Imperialism over the span of several centuries. From the perspective of an Imperialist, conquering other lands and peoples might be viewed as an unqualified success. However, from the viewpoint of the indigenous peoples who suffer at the hands of Imperialists, these so-called "achievements" are the source of widespread oppression and misery, and in turn discontent, to which any observant Native American or South African native could attest.
The extent to which great socio-political achievements have caused great discontent also depends on the perspective of time. For example, F.D.R.'s New Deal was and still is considered by many to be one of the greatest social achievements of the 20th Century. However, we are just now beginning to realize that the social-security system that was an integral part of F.D.R.'s social program will soon result in great discontent among those workers currently paying into the system but unlikely to see any benefits after they retire.
To sum up, I agree that great achievements, both individual and socio-political, often result in great discontent. Moreover, great individual achievements can result in discontent for both the individual achiever and the society impacted by the achievement. Nevertheless, in measuring the extent of discontent, we must account for varying personal and political perspectives as well as different time perspectives.
