“Unnatural, mummy? You tell me, what’s nature’s way? If poison mushrooms grow and babies come with crooked backs, if goiters thrive and dogs go mad and wives kill husbands, what’s unnatural?”
Richard, The Lion in Winter
One of the claims to which people seem peculiarly susceptible at the moment is that if something is “natural”, it must be good. “Natural” foods are believed to be uniformly healthy. The finding that some particular behavior (say, polyamory) is found in nature is taken to be some sign that it is a good thing.
I think a fair amount of this results from our culture having lost a sense of tragic vision in regards to nature — we naturally assume that unless some active force comes along and makes things bad, that they will be good. This could not be farther from a traditional view of nature. While neo-pagans are sure that being “in tune” with nature would be a blissful and pleasant state, real pagans of the ancient world saw the natural forces that were bound up with their gods as capricious, sometimes cruel, and almost always unconcerned with the impact of their actions upon mortals.
