Macbeth isn’t “a tale told by an idiot,” but it does have a flawed understanding of the environment, and we must learn from those flaws to improve environmental communication.
In Macbeth, Shakespeare goes to great lengths to present the title character’s usurping of the Scottish throne as an affront to nature. He does this to protect the “divine right” of kings to hold power, a move intended to curry favor with James I. In this way, the King Duncan of the play and his line embody the “laws of nature,” which, when broken, throw Scotland into an unnatural state of turmoil. As Lady Macbeth’s doctor says, “Unnatural deeds do breed unnatural troubles.”
For Haila and Dyke, nothing, including deeds and troubles, can be unnatural. Nature is simply the parameters of what is possible. As a result, they argue “that nature’s speech means nature’s presence in everything we humans do.” Killing someone, whether they are a monarch or not, is no more unnatural than not killing them. Humans have simply determined that killing, in most circumstances at least, is morally wrong, and that is where people who study environmental communication must pay special attention.
To argue that some action humans take is “unnatural” is an untenable position. It responds to a question of fact (whether something is true, if it exists, etc.), and that question has only an answer in the negative, setting up the person making the argument for failure. No matter how many human elements are involved in an activity, whether it’s hiking a mountain, emitting carbon pollution, clearcutting a forest, or producing chemical toxins, it can never be unnatural because the environmental parameters allowed for it.
We can still argue against certain actions because of their potential environmental harm, but we must avoid statements based in the issue of what is “unnatural.” For example, if we want to stick with questions of fact, we can argue that an action will create chaos in the environmental system or that such chaos will cause harm to the system. Unlike the claim about unnaturalness, these claims of fact have the potential of being proven as true. We can also examine questions of value (whether something is good or bad, moral or immoral, etc.), which is what Shakespeare seems to have tried to explore with the issue of unnaturalness in Macbeth’s actions. We can claim that some action we take within our environment is immoral (like driving other species to extinction). This, like the questions of fact about systemic balance, is also a question that can be investigated with the potential of the claim emerging victorious.
As compelling of a play as Macbeth might be, it represents a faulty line of thinking about the “laws of nature,” and if we want to improve our communication and understanding of our environment, we must choose lines of inquiry that diverge from the idea of unnaturalness.
