美国匹兹堡大学里舍尔教授探讨了“地球的科学”的两种可供选择的科学认识形态——一种是受历史性制约的科学认识形态,另一种是在现代文明范围内已变成现实的科学认识形态——的问题。假设这两种可供选择的科学认识形态能在与我们完全不同的条件下,例如在有另种文明的其他一些行星上产生和发展的话,那么地球的和“地球外”的科学之间能有多大的区别呢? Professor Rischer of the University of Pittsburgh in the United States explores two alternative forms of scientific understanding of Earth Science - one that is historically constrained by the scientific understanding and the other that has become, within the framework of modern civilization, Realistic form of scientific understanding - the problem. Assuming that the two alternative forms of scientific understanding can emerge and develop under fundamentally different conditions from ours, for example on other planets of another civilization, then the Earth and the “extraterrestrial” science can How big is the difference?
