Intro to Nature: Part One
In his book, The Modeling of Nature, Fr. William Wallace, O.P. states the problem that we agreed to tackle in our last post: “though it is easy to form a general idea of nature and the natural, it is difficult to define nature precisely and to differentiate things and processes that are natural from those that are not.” In this post and the posts to come, with the help of Fr. Wallace and others, we are going to nail down what the word “natural” means.
Fr. Wallace distinguishes two ways to conceptualize nature: (1) What is free from human intervention and contamination. So, natural versus artificial. Contrast, for instance, Lake Michigan and the man-made ponds in city parks. In this sense, natural things exist on their own, indifferent to mankind’s needs or desires. We did not “have a say” about whether Lake Michigan exists, but we did create various ponds for our own enjoyment. (2) Activities or behaviors that originate from within an agent without force or coercion. For example, no one must remind beavers to build dams or ask bees to make honey. They just do. This sense of nature is what we mean when we say that things “do what comes naturally.”
Now, let’s take a closer look at the first sense of nature that Fr. Wallace distinguishes: that which is free from human influence (or: that which is opposed to the artificial). Think of all the things that we consider natural: plants, animals, bodies of water, rocks and rock formations, the planets, chemicals and compounds. We could even include natural phenomena like storms, natural disasters, or the water cycle. Now, what makes all of these things natural as opposed to artificial? The distinction that Fr. Wallace makes is that natural things exist or come into being on their own. Why does this make something natural? Well, if something comes to exist on its own, it means that it does so regardless of mankind’s needs, wishes, or desires. Recall our contrast between Lake Michigan and our man-made ponds. While we may use and enjoy Lake Michigan—use it for swimming, fishing, sailing, etc.—we did not create it for this express purpose. The man-made lakes, however, were designed by someone and deliberately placed in the park for us to use and enjoy.
Someone might object that the man-made ponds are still made out of natural things like rocks, water, and plants, and they might be populated by animals like fish or ducks. So, why can’t we consider them natural, like Lake Michigan? While it is true that the man-made ponds are made out of “natural stuff,” this still doesn’t change the fact that these natural things were arranged, configured, put there by someone else.
In fact, there are many examples of artificial things that are made from natural parts. For example, wooden furniture is “natural” insofar as it is carved from naturally-occurring wood. Cotton clothing is natural insofar as it is made from the cotton plant, and granite counter tops are natural insofar as they’re cut from slabs of naturally-occurring granite. Notice that all of these things are harvested, altered, and designed specifically for human purposes. That fact is what makes them artificial rather than natural. Imagine how out of place a wooden kitchen chair would look amidst a forest of redwood trees!
Now that we have this first sense of the natural squared-away… stay tuned for part two! In part two, we will discuss the second sense of nature that Fr. Wallace distinguishes and how it is both related to and different from the first.
