Lisp值得学习，因为当你最终掌握它时，你将获得深刻的启蒙体验；这种体验将使你在余下的日子里成为一个更好的程序员，即使你从未真正大量使用Lisp本身。
Lisp is worth learning for the profound enlightenment experience you will have when you finally get it; that experience will make you a better programmer for the rest of your days, even if you never actually use Lisp itself a lot.

Philosophy is a battle against the bewitchment of our intelligence by means of language.
