再谢留兄讨论，仍感话没说完，不吐不快，望兄多包涵：谁是“事前诸葛亮”也是我们后人的评价。梁启超同时代的有许多人想作诸葛亮。It just happened that Liang turned out to be correct because the course of the history happend to move in the direction of Liang predicted. But the history could progress in a different way to make anothe persone as “事前诸葛亮”. To put it another way, if you have a hundred people to predict where a train would go, one of them has to be correct and he would be considered by the people in the future as a “事前诸葛亮”. Do you see my point?

当然大趋势可以有“必然性”。但只能是极其普遍的大大趋势，例如：科学技术的不断更新，等等。
