Having purpose? I think purpose and questions of purpose are actually part of the human mind's obsession with meaning and interpretation. Other animals with complex nervous systems (eg mammals etc) don't seem to be preoccupied with this question, although they do have limited capacity for identifying things. Humans however look at everything, not just communications, and interpret it. That results in an evaluation that is usually positive or negative. When looking a plant we see it as good or a weed, medicinal or poisonous etc. This cerebral capacity we have can turn against us when we look at our own meaning, purpose, use, value and all. I think context has a lot to do with interpretations, as the way we interpret things contemporarily is for its use or purpose and if it has none it is useless or garbage. If people were more about the aesthetic nature of things, and saw things with just purpose like cars and machinery as ugly and undesirable maybe we would look for the beauty in life instead, which is rather abundant.
