Nature (Philosophy) and Nature (philosophy): Difference between pages

Nature is a word used in two major sets of ways, which are inter-connected in a complex way, for reasons related to the history of science and metaphysics, particularly in Western Civilization.

1. In modern scientific writing "nature" refers to all directly observable phenomena of the "physical" or material universe, and it is contrasted only with any other sort of existence, such as spiritual or supernatural existence. In a scientific text, the unqualified term “nature” normally means the same as “the cosmos” or “the universe”.

2. Historically, and also in casual speech, “nature” does not include all things, because it excludes the artificial or man-made. For example it generally does not include manufactured objects, and also generally does not include human interaction. In this case, the unqualified term “nature” generally means the same as “wilderness” or “the Natural environment”.

Connected to this second meaning, "nature" also refers to the essential properties of any particular type of thing.

To understand how the different meanings developed from one historical concept, we must look at the history of the term “nature”. Trying to explain the regular “ways” of things, and how they change and exist, led to a peculiar concept of nature amongst the ancient Greeks. Western science and philosophy derives much of its peculiar character from debates arising from this ancient treatment of nature. To consider other civilizations, compare logos, tao, and dharma.

The English word derives from a Latin term, natura, which was in turn a translation of a Greek term, physis (φύσις). Natura is related to the Latin words relating to "birth", while physis relates to Greek words relating to "growth" in plants and animals. Hence the original classical concept of nature was of particular natures or “essences” of types or species of things. In the Odyssey, Homer uses the word to refer to the normal physical properties and the way of growth of a particular species of plant.

The etymology, referring to birth and growth, shows us that in classical times the essences or typical characteristics of natural (non man-made) things were understood not just as results of birth, growth and other natural changes, but also somehow as a pre-existing guide to those natural changes. In other words, natures were somehow understood as causes, and not just effects.

Most famously, Plato and Aristotle, presented the argument that there might be "forms" which are causes of the types of things we see in nature. This was explicitly a thinking-through of the implications of the pre-Socratic concept of the natures of types or species of things. But this understanding of nature was controversial from the start, and both Plato and Aristotle often seem tentative about this theory.

In contrast, modern science has come to insist upon looking at nature as a single whole. It denies the usefulness of the concept of natures of particular types of things, which was the older meaning of the word "nature".

As already mentioned, in philosophy the question of nature lies at the heart of the key philosophical debates between arguments such as those sometimes called idealist and realist, as well those called determinist and those which give special position to free will. However the most important development in debate about nature is the development of modern science.

Francis Bacon was apparently influenced by Machiavelli in arguing that knowledge should avoid building up hypotheses based upon anything which could not be directly observed in the light of day. (Both authors wrote extensively about history and politics.) He was clearly also influenced by the debates in Europe caused by recent speculation about astronomy - for example that of Gallileo and Copernicus. In his Novum Organum he argued that the only forms or natures we should hypothesize are the "simple" (as opposed to compound) ones such as the ways in which heat, movement, etc. work. For example in aphorism 51 he writes:

51. The human understanding is, by its own nature, prone to abstraction, and supposes that which is fluctuating to be fixed. But it is better to dissect than abstract nature; such was the method employed by the school of Democritus, which made greater progress in penetrating nature than the rest. It is best to consider matter, its conformation, and the changes of that conformation, its own action, and the law of this action or motion, for forms are a mere fiction of the human mind, unless you will call the laws of action by that name.

Following Bacon's advice, forms are now more commonly replaced by “laws of nature” or “laws of physics” in all scientific thinking. To use Aristotle’s well-known terminology these are descriptions of efficient cause, and not formal cause or final cause. It means modern science limits its hypothesizing about non-physical things to the assumption that there are regularities to the ways of things which do not change. Modern scientists often even argue that they have in this way avoided any sort of metaphysics, although this is debated, because by definition modern science can never prove this assumption to be true.

Modern science normally sees nature, even human beings, as "matter in motion", obeying certain "laws of nature" which science seeks to understand. For this reason the most fundamental science is generally understood to be "physics" - the name for which is still recognizable as meaning that it is the study of nature.

Matter is commonly defined as the substance of which physical objects are composed. It constitutes the observable Universe. According to the theory of relativity there is no distinction between matter and energy, because matter can be converted to energy (see annihilation), and vice versa (see matter creation). Philosophically, matter constitutes the formless substratum of all things, which exists only potentially and from which reality is produced. In the sense of content, matter is also used in contrast to form.

Despite the importance of modern science, the distinction between the natural and the artificial - with the latter being understood as that which has been brought into being by a human or human-like consciousness or mind – is still important in modern philosophical discussions about nature. Indeed, the most common use of the word Nature in modern times is probably the one which is roughly equivalent to Wilderness or Natural Environment. See Nature.

The idea that the natural type of coming into being is different in kind from natural coming into being is often associated with the concept of free will. This view is distinguishable from, for example, from views such as behaviorism, determinism, and the chemical model within modern psychiatry and psychology, which have tended to emphasize the idea that the human mind itself might conceivably be explained as "matter in motion" the same as the rest of nature as a whole.

One approach is to exclude mind from the realm of the natural; another is to exclude not only mind, but also humans and their influence. In either case, the boundary between the natural and the artificial is a difficult one to draw (see mind-body problem). Some people believe that the problem is best avoided by saying that everything is natural, but that does little to clarify the concept of the "artificial". This solution simply presumes that the modern stand point is correct, and that there is no "nature of man": even reason is simply an effect of the interaction of matter in motion working according to "laws of nature". The distinction between the natural and the artificial goes back to a time when this was not the normal understanding.

And yet ambiguities about the distinction between the natural and the artificial still animate much of art, literature and philosophy. In the 18th century, automaton provided the basis for Descartes' mechanism theory of the organism.

Another approach is to distinguish natural processes and artificial (man-made) processes. In this viewpoint, a process is deemed to occur either at the conscious behest of man, or not. For example, flipping a light switch might illuminate a room, or perhaps a sunrise might illuminate that room. In this viewpoint, the sunrise would be termed a natural process; the decision of a human being to flip the light switch would be termed an artificial illumination, in contrast. In this viewpoint, artifice (art or literature) is clearly the result of willful human action; furthermore, the act of stating a philosophical position could also be a willful action (and hence at the behest of man), whether or not the content of the philosophy were to be about science. Natural processes, especially as used by organisms, may also be known as wildness.

The distinction between what is natural and artificial was initially important, as far as we know, to the ancient Greeks. Perhaps their main interest was in distinguishing good aims from ones that have been distorted. In modern times, such philosophers as David Hume and John Stuart Mill have criticised attempts to give any moral importance to the distinction.

Main article: Idealism.

Main article: Metaphysics.

Modern science has also not ended Idealism, or more generally it has not ended speculation about metaphysics beyond just "laws of nature". Apart from the position of the world's main religions, philosophers such as Immanuel Kant have continued to argue the case for positions in conflict with that of modern science.

The writer Steven Fry has commented that if we look around us, anything ugly that we see will have been created by human hands; this exemplifies a widely held view that nature is intrinsically beautiful. That the beauty of nature has been celebrated by so large a proportion of our art is further proof of the strength of this association between nature and beauty. Many scientists also share the conviction that nature is beautiful; the French mathematician, Jules Henri Poincaré (1854-1912) said:

"The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living. Of course I do not here speak of that beauty that strikes the senses, the beauty of quality and appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmonious order of the parts, and which a pure intelligence can grasp."

A common classical idea of beautiful art involves the word mimesis, which can be defined as the perfection and imitation of nature. It is in nature that the perfect is implied through symmetry, equal division, and other perfect mathematical forms and notions. Plato wrote about Socrates and his ideas about how the perfect forms of things exist, and in nature we see the copy of this eternally existing form.

The term natural science is used in a variety of ways, primarily:

• to denote the study of natural processes as opposed to human activities, in contrast to the social sciences; and
• to denote those sciences which employ the scientific method, in contrast, for example, to mathematics or computer science.

The term natural philosophy formerly named the scientific discipline now known as natural science.

Natural theology straddles the disciplines of theology and philosophy of religion.

In education and related areas, the contrast "natural/artificial" can appear as "nature/nurture".
