And this is a nice thought. As we try desperately to hang on to artworks, preserve paintings, sculptures, first editions, manuscripts, even buildings, eventually they will all crumble, inevitably to the mists of time. But the inherent skills and habits of human beings, of nature itself shall remain for far longer than anything we have created. Its sobering to think this; natural inclinations to walk, socialise, make tools, survive, will outlast any Da Vinci painting, as sad as it is to lose any artwork. The artwork that is the natural world shall continue, the sun shall always rise, no matter how high the sea does.
