The saints are always taking maximizing the utilization of everything as the best, so nothing useless.

永远以物尽其用为善，所以没有无用的事物。

So unlike the little toe, which may eventually vanish and is equally useless, the appendix is likely to stay with us for a long time - just hanging around doing nothing.

所以，不像小拇指，可能最终会退化而且同样没用，阑尾很可能还会存在很久——晃来晃去，啥事也不做！

But just as syntax is nothing until words are built upon it, so too is a sense of right and wrong useless until someone teaches you how to apply it.

但是正如在上面有单词构成之前，语法毫无用途一样，对正确和错误的感觉毫无用途，除非当有人告诉你如何来应用它。
