社会进步的限制因素

The concept of inherent limits to development arose mainly because development in the past was determined largely by the availability of physical resources. Humanity relied more on muscle-power than thought-power to accomplish work. That is no longer the case. Today mental resources are the primary determinant of development. He who drove a simple bullock cart has now designed ships and aircraft that carry huge loads across immense distances. He has tamed rivers, cleared jungles and even turned arid desert lands into cultivable lands through irrigation. By using his brains he has turned worthless sand into powerful silicon chips that carry huge amounts of information and form the basis of computers. Since there is no inherent limit to the expansion of man’s mental resources, the notion of limits to growth cannot be ultimately binding.

资源对社会进步的制约及四大资源

It has been thought that the capacity for development is severely limited due to the inherent limitation in the availability of natural resources. Resources can be divided into four major categories: physical, social, mental and human resources. Land, water, mineral and oil, etc. constitute physical resources. Social resources consist of society’s capacity to manage and direct complex systems and activities. Knowledge, information and technology are mental resources. The energy, skill and capacities of people constitute human resources.

Though physical resources are limited in their availability, the same cannot be said about social, mental and human resources which are not subject to any inherent limits. Even if these appear to be limited at present, there is no fixity about the limitation and these resources can and will continue to expand over time and that expansion can be accelerated if appropriate strategies are adopted. In recent decades the rate of growth has accelerated dramatically.

物质资源和非物质资源在社会发展中的作用

The role of physical resources tends to diminish as society moves to higher levels in the scale of development. Correspondingly the role of non-material resources keeps increasing as development advances. One of the most important non-material resources is information, which has become a key input in modern times. Information is a non-material resource that does not get exhausted by

distribution or sharing. Greater access to information helps increase the pace of its development. Ready access to information about economic factors helps investors to immediately transfer capital to those sectors and areas where it will fetch a higher return. The greater input of non-material resources helps explain the rising productivity of societies in spite of a limited physical resource base.

非物质资源可以提高物质资源的生产力

The application of higher non-material inputs also raises the productivity of physical inputs. Modern technology has helped increase the proven sources of oil by 50% in recent years and at the same time reduced the cost of search operations by 75%. Moreover, technology has shown that it is possible to reduce the amount of physical inputs in a wide range of activities. Scientific agricultural methods demonstrated that soil productivity could be raised by application of synthetic fertilizers. Dutch farm scientists have demonstrated that a minimal water consumption of 1.4 liters is enough to raise a kilogram of vegetables compared to the thousand liters that traditional irrigation methods normally require. Henry Ford’s assembly line techniques brought down the man-hours of labor required to deliver a car from 783 minutes to 93 minutes. These examples show that the greater input of higher non-material resources can raise the productivity of physical resources and thereby extend their limits.

社会文化进化论

Sociocultural evolutionists agree that the evolution-like process leads to social progress. Sociocultural evolutionism represented an attempt to formalize social thinking along scientific lines, which was later influenced by the biological theory of evolution. If organisms could develop over time according to deterministic laws, then it seemed reasonable that societies could as well. They developed analogies between human society and the biological organism and introduced into sociological theory such biological concepts as variation, natural selection, and inheritance—evolutionary factors resulting in the progress of societies through stages of savagery and barbarism to civilization, by virtue of the survival of the fittest. Together with the idea of progress there grew the notion of fixed “stages” through which human societies progress, usually numbering three—savagery, barbarism, and civilization—but sometimes many more.
