【正确答案】More and more people of insight believe that human civilization is undergoing a profound transformation and is heading for a new era. Some people think that it will be a new era of information civilization, while others think that it will be a new era of ecological civilization. Accordingly, two new philosophies, namely, information philosophy and ecological philosophy, came into being. They both criticize Descartes’ mind-matter dualism and Kant’s dichotomy between human beings and other beings. However, information philosophy has a strong tendency of computerization and reductionism, which leads to monism and there is the possibility of supporting fully knowability. While based on quantum physics and the complex science of ecology, ecological philosophy puts forward the outlook of vitalism, humble rationalism, epistemology and values beyond materialism. Ecological philosophy will be the essence of the spirit for the new era of ecological civilization. Nature is a living, all-encompassing, changing language, while human language (including mathematical language) solidifies once spoken or written. The development of agricultural civilization is green development, and the green development of agricultural civilization is the green development of low technology. The development of industrial civilization is "black development", and ecological civilization is the retrace of green development. However, the green development of ecological civilization is the green development that inherits the high-tech industrial civilization. It is neither a single growth of material wealth, nor a single economic growth, nor a single progress of science and technology, but a comprehensive development that includes technological growth, political progress, cultural prosperity and spiritual improvement.
