我们不能否定理论的重要性,但是理论不是灵丹妙药,有时与现实是不合拍的。你的问题使我想起了爱因斯坦的话:“In theory, theory and practice are the same. In practice, they are not.” 其他人的话也很有意思:The difference between theory and practice is bigger in practice than in theory.  In theory there is no difference between theory and practice. In practice there is.  It may come out all right in practice, but it'll never work in theory!  In theory, practice is simple.  Reality is the murder of a beautiful theory by a gang of ugly facts.
