[2]关于爱因斯坦信的译文问题
。李约瑟(Joseph Needham)教授在1961年发表的论文《中国科学传统的贫乏和胜利》中全文引用了爱因斯坦的这封信。……这封信的英文原文如下：
Dear Sir．
“The development of Western science has beenbased on two great achievements，the invention of theformal logical system (in Euclidean geometry)by the Greek philosophers，and the discovery of the possibility of finding out causalrelationships by systematic experiment (at the Renaissance).In my opinion oneneed not be astonished that the Chinese sages did not make these steps.
