What is the point of art? Well I pretty much discussed a fairly robust definition on my website Art ClearlyExplained.Com . It seems to cover most aspects quite well. But it did not consider the actual physical nature of art. What do I mean by that?
Well although art appears to be a purely cultural feature of humans it seems to be heavily based in the physical world. It is largely inspired by the natural world. It really comes down to a question of why do people create art in the first place? The first reason that comes to mind is that people have time. In other words people have met a bunch of other needs, like food, shelter etc and can use 'spare time' to create something random.
