LISP is incredibly powerful.
For example to search "trees". I've only used it in a CS class and it takes a paradigm shift in thinking to use it.
But, don't try to use it to add two numbers.

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
-- Isaac Asimov
