In the Theaetetus Plato tried to show the danger of conceiving the world as but a Heraclitean flux; for discourse to be possible, we need something like general terms. Or in other words, there must be something more than the mere perception of each individual in each moment. This "must" is not the Kantian "must"--in the sense of a transcendental precondition for cognition--but a "must" that is thoroughly practical: without general terms, we cannot even talk to each other.

这套想法的内容本身，我是同意的；但我不大认同这种笛卡儿式的method of doubt(即为了捉紧一些颠扑不破的真理而在方法上质疑一切有理由被质疑的见解)，尤其是在灵性而非物性的探索上，因为这种怀疑方法所带来的结论，往往不会令人高呼Heureka，而只会使人吐出一句so what--你考虑的可能是某种观念的实际意义，而我重视的则是某种方法的实用价值。
