Sure we can throw around meaningless circular terms like god, but what does god mean? You have an idea but how do you know your idea is correct. For that matter how do we know that our definition of love is? In most "love" relationships I've seen it's mostly irrational infatuation with someone of the opposite sex, which wanes with time.

Love is supposed to be, free, unlimited, unconditional, and last but not least unity. Why can't we act like it is? Why do we attribute words to something if we can't even enact those words. Instead we define terms as such but act as other people have modeled such behavior.
