A phenomenal song, but come on - that's a CLASSIC Nietzsche quote (and one of my favorites), NOT a Twain quote. You should probably check your sources before you attribute a quote from a German existentialist to an American satirist. They're kinda different.
Why people spend some much time complaining about a lack of love in the world and then try to block laws and policies that would recognize the existence of real, meaningful love between 2 people is beyond me. At any rate, keep it up you crazy star child.
"We think too much and feel too little." Beautifully succinct.
