“道可道非恒道”,老子如是说。“科学没有永恒的理论”,爱因斯坦如是说。相隔两千年数万里的两位智者发现了相近的道理,却经历了不同的实践之路。老子的中华重道而轻器,终因挨了洋鬼子利器之重击,方发愤重“器”以自卫自强,爱因斯坦所在的西方则争相把科学引向重器之科技而轻 “Tao can be a non-permanent road,” said Lao Tzu. “Science has no eternal theory,” Einstein said. The two wise men separated by thousands of years in the two thousand years discovered similar truths but experienced different practices. Lao Tzu’s Chinese roads were light and heavy, and eventually they were smashed by foreign devils. The Fang’s indignant “instrument” was self-defense and self-improvement, and Einstein’s Western was arguing for the science to lead the heavy technology and light.
