Meaning in Chemicals

In answer to the question as to whether or not love is meaningless, I would say yes and no. It depends on your perspective. Yes love is purely chemical and of the mind, yet does this necessarily mean that it is devoid of meaning? As an atheist I believe that the universe is a random occurrence, and for me this leads to the additional belief that meaning as a concept is a purely human phenomenon: something can only have meaning if a human being gives it meaning. To say that love is meaningless just because it is chemical is missing the point. However I do think confusion comes when people assume that something random has meaning and purpose ordained by another consciousness. For example a religious person could persuade themselves that a random accident was ordained by God, and will therefore have a reason, and this is the dangerous part because from a random event a human imagination could construe just about any meaning. This can be seen in the reaction of the Christian Right in America to the devastation of Hurricane Katrina. A perfectly random meteorological event, which one Reverend Peter Marshall attributed to God's punishment for sexual promiscuity and tolerance of homosexuals. I really do believe that the only purpose in existence is human purpose, and the only meaning is human meaning. World events are far to crude, brutal, not to mention random, to be ordained by any loving God, or at least any God with half decent aim.
