Understanding Metaphors and Parsecs discusses fiction and nonfiction and how the two differ and how the two are differently understood. Both fiction and nonfiction are examined in terms of meaning. Meaning in fiction is understood in a very particular way. What is it about meaning in fiction that rewards understanding? Some answers are suggested. While various types of nonfiction are mentioned, it is scientific writing that is dwelt upon. Meaning is crucial to scientific writing and the understanding of meaning in scientific writing poses very particular challenges. These challenges are closely examined.
Put aside, for the purpose of the present discussion, fiction’s use of plot, character, style, setting, and all the other elements used by fiction, save one, meaning.
Meaning in fiction can be grasped at a superficial level based the words and terms being employed. The words and terms used fall into two categories: the dictionary definitions of words and terms, and historical, mythical, religious and cultural references.
A good dictionary will immediately solve problems of vocabulary. A word used in a particular context by the writer might not make its meaning immediately clear. The dictionary should solve that.
Historical, mythical, religious and cultural references are more problematic. The use of a particular reference, of what ever kind, by the writer, may be overt or it may be illusional. Overt references are there on the page, such as the phrase the Jazz Age. References by way of illusion are more problematic. The context of the story might suggest the setting for the illusion. or an earlier, more overt reference in the same work. The writer may betray a fondness for certain kinds of illusions, say biblical. The writer will be relying, for the most part, on the reader’s knowledge to understand what is being alluded to. This reliance may be as simple as a knowledge of the writer’s previous works.
The use of references, either direct or indirect, is one of the strengths of fiction. The use of references deepens meaning and moves the text away from the merely literal.
References are only one means by which fiction invests itself with meaning. Fiction also uses metaphors and symbols. Metaphoric language, the use of figures of speech such as symbols and metaphors, divides, just as with references, into the overt and the not so overt. Symbols are overt. This doesn’t mean that you will spot that a writer is employing a term as a symbol. The word cross, for example, has a literal meaning, with crucifix being a close synonym. In addition to using the word in a literal sense, the writer may be employing it in a symbolic sense, and here we have a pointer as to how religious, cultural and other references are placed, or embedded, in the work.
Metaphors, and all of the other figures of speech, are less obvious. In fact, the strength and skill of a writer will rest with the ability to use metaphors, an other figures of speech, appropriately and well. Metaphors work by comparison. Fragility, for example, if compared to the murmuring of a breeze will suggest one thing, but if compared to a twig, will suggest something else.
A tale teller will weave a story out of warp and weft. The warp of a tale consists of the elements we referred to in the first paragraph: plot, character, and so on. Weft, the references and the metaphoric language, provide the riches of the story, emphasising its resonance with the reader. Quite simply, this resonance is an emotional appeal. But an emotional appeal that is subtle. Subtlety is what metaphoric language is all about.
The understanding of the metaphors and symbols may not be immediate. Firstly, metaphors and symbols may be used as public metaphors and symbols, those used by society at large, at least in the society in which the writer is writing, and accepted by that society’s members and readers. Or the metaphors and symbols may be private; in other words, particular to that author. In either case, the meaning of any metaphor or symbol may only be apparent from its context, and its repetition in different contexts. Or its employment may be so slight as to render as uncertain whether it is there in the text at all.
The art in fiction comes from the skill in applying effects to the story that work. Figures of speech, as already mentioned, will frequently be used in fiction and their meaning may be implied rather than spelt out. If implied, then interpretation will come into play: “This is what the author means, or intends to mean …” A number of interpretations may be possible and the author is only one possible source of interpretation. If living, the author may, or may not, be able to say with any certainty what he or she meant in a particular phrase or passage.
Summarizing what we have said so far, fiction seldom has direct literal meaning. Understanding may be gained unconsciously or subconsciously, and such understanding will be difficult for a reader to convey to others, even to those who have also read the work in question.
In fiction, meaning is often suggested rather than made plain. The fiction may be said to have layers of meaning that may be penetrated only by repeated reading. Good fiction is said to be that fiction which rewards successive readings.
At the heart of fiction is understanding. A book, story, or passage may be read and understood but its full meaning may not be immediately grasped. This may not be essential to the enjoyment of the work. If fact, some works may require successive readings to fully penetrate in terms of meaning. However, for most readers, a single reading will reward sufficient meaning for the work to have been successful in its impact on the reader. The measure of certain kinds of fiction is this ability to reward successive readings with greater and greater penetration of meaning and of understanding. This is what we usually mean when we speak of a work of art.
As already stated, this deeper penetration of meaning is not necessary for the work to be fully understood. Now, this is absolutely not true for certain kinds of nonfiction writing. For those works to be fully understood, a full penetration of meaning is required. Let’s look generally at nonfiction forms of writing as a prelude to discussing this more intractable form.
Nonfiction is a broad church of writing, so to speak. It takes many forms. Some of these kinds of writing resemble fiction in some respects. Such writings may not be viewed necessarily as nonfiction. On the other hand, they may. Prime examples of such writing are philosophical and religious writings, amongst others. Such writings frequently employ the devices familiar in fiction. In attempting an understanding of such writings, the reader faces similar difficulties to those faced in some forms of fiction. Such writings frequently also reward re-readings in an effort to penetrate meaning.
Let us turn now to a discussion of what most of us will agree is nonfiction. Nonfiction takes many forms, as we have said. By its self-evident definition, nonfiction writing is all those kinds of writing which is not fiction. Nonfiction will include, but not be limited to: most journalism, dictionaries, self-help manuals, travel guides, memoirs and biographies, and all of the soft and hard sciences. Soft sciences are those sciences which do not lend themselves easily to experimental proof. Examples are economics, sociology, archeology, psychology, and so on. Hard sciences are those sciences which rely upon experimental proof for their furtherance. Physics and chemistry are obvious examples of hard science. Biology, with the rise of molecular science, more and more becomes a hard science. Mathematics is problematic. Applied mathematics is generally subject to experimental proof but abstract mathematics is not. On the other hand, abstract mathematics does not use, as its principal conveyance of meaning, English or other spoken language. Abstract mathematics generally uses specific symbols and the language used has particularly specified meanings. Understand the language and you will not necessarily understand the math, because abstract mathematics is about the conveyance of ideas and concepts. The language is used by abstract mathematics as a means of conveying those concepts and ideas.
In almost all of the nonfiction writing we have discussed so far, there will exist both a popular level of writing and a more specialized form. The distinction between the two lies in the vocabulary used. The sentence you have just read is at the heart of the discussion of nonfiction we are about to embark upon.
The understanding of scientific writing relies heavily upon the understanding of the fundamentals and principles involved. Once again a distinction has to be made between popular and more proper or technical scientific writing. The difference between the two are many.
At the most basic level, in considering popular scientific writing, you have, on the one hand someone who is a writer, who is skilled in the craft, who approaches the scientific area and makes a sincere effort to understand it and who attempts to convey that understanding to the reader. On the other hand, you have the scientist, who writes for a living. Most scientific research has to be written up. Scientific writing at this level is so arcane that questions of style and readability are often beside the point. The specialist scientific writer has to convey information to others in the specialty, usually in the form of summarized data. Not an easy job, to be sure, but assuming that the data is accurate; the conveyance of it is straight forward, if not downright laborious.
So, you have, on that other hand, such scientific specialists adopting to write in a more popular style. Very few specialists are able to achieve this skill. By its rights, the popular scientific writing is better served if the writer is a specialist who fully comprehends the terms being used. After all, writing is a skill that both the popular writer and the scientist acquire early on in life. But it is not so easy. There are many more popular science writers who are not specialists in the science than the other way round.
It is one thing to acquire an understanding of the terms of the scientific specialty. It is quite another matter entirely to be able to explain those terms to others, including, it may be said, fellow specialists. The first two sentences of this paragraph, together with the key sentence of earlier now move to the heart of where we are headed.
At one level, what I might term proper scientific writing will aim itself at those readers who are familiar with the subject matter and will have a background, education, training and experience in that field.
Popular scientific writing aims at a larger audience, one that will include those with a general scientific background, or background in a field different from the field of the topic being written about.
A distinct hallmark of popular scientific writing will be the avoidance of the terms particular to the field being written about or, at the very least, a ready explanation of those terms that are used. So popular scientific writing on astronomy, for example, might employ the term light years without explaining the term. Most readers will grasp what is being implied by a light year, without explanation. There again, it may use the term astronomical unit (AU) because the term can be readily explained. Such writing, though, would avoid a term such as parsec. The expressions light years and astronomical unit can be explained in terms which are readily understood by most readers, scientific and non scientific. The term parsec is not so readily explainable as we shall see.
I trust I do not try your patience, dear reader, too far if I attempt to illustrate how explainable the terms light years and astronomical unit are. If that is the case, then skip the following sentences and go to the next paragraph. Roughly put, a light year is the distance traveled by a ray of light in a vacuum in one year. I say roughly because the year in question is a tropical year, which is the time taken by the earth to make one revolution of the sun. It is also known as a solar year. If we were measuring, we would have to be more precise in our definition but we have defined light year sufficient enough for the sake of understanding. The astronomical unit is the mean distance from the centre of the earth to the centre of the sun. Mean distance because it is that distance between when the earth is furtherest away from the sun and when the earth is closest to the sun. You may take my word for it, for the moment, that parsec takes rather more words to adequately explain.
In fact, discussion of the term parsec might very well be the key to any discussion of the understanding of proper scientific writing. I don’t suggest the actual term as such, but to point to the fact that difficult concepts are invoked on the way to understanding the term. Any similar term would serve the purpose. What we have here is a distinct process through which we go on our journey to fully comprehending the term in question.
At the most basic level, an understanding of proper scientific writing will rely absolutely on an understanding of its basic terminology. The basic terminology will be that terminology without the employment of which proper writing on the subject is seriously impeded if not made impractical. At the same time, proper scientific writing will employ terms which are not central to an understanding of the topic and whose meaning can be imperfectly understood without seriously impairing comprehension of the topic. This is not true of all the terms that such writing will employ. Readers will determine from their understanding which terms are key and which are secondary.
However, if the discussion is on the relative motion of cosmic bodies and the term parsec is employed frequently, the discussion will be imperfectly understood, if at all, if the term parsec is not fully understood. In reading of the relative motion of cosmic bodies, the term parsec is used to refer to distance between cosmic bodies and is the preferred term used by astronomers over the term light years, and, for that matter, astronomical units. I do not propose to examine the term light years and why parsec is the preferred term. My interest lies in the parsec as an example of a highly technical term which we might break down into its basic parts in an effort to fully grasp what is meant by the term. The basic parts will be those words and terms used in the definition of the term.
In seeking to fully understand the term parsec so that I could comfortably explain it to others, such as you, dear reader, it took the examination of a number of sources, each of which struggled to explain the term, before I realized that parsec is a contraction. It looks like a contraction, but none of the initial sources consulted said so. Sec is obviously short for second and the second in question is as in seconds of an arc, at that. To step back for a moment, a circle can divide into degrees, minutes and seconds. An angle subtended in seconds is a small angle indeed. How small? Well, if there are 360 degrees in a circle, 60 minutes to a degree and 60 seconds to a minute, then a second of an arc is 0.0003 degrees, to four decimal places. Par I eventually discovered is a contraction of parallelax.
Now, even before I go further, I am sure most readers will require a moment to refresh in their minds the meaning of parallelax, as I had to. Parallelax is perhaps the most difficult part of parsec to understand, so be encouraged. Once we are past that hurdle, we are on the home straight.
Parallelax describes the change in apparent position of an object, relative to its background, caused by a shift in position of the observer. If we are discussing an object in space, and the observer is viewing the object from earth, then, given any period of time, the position of the object will appear to have moved due to the motion of the earth. Other factors are involved but we will, just as good scientists do, ignore them for the purpose of simplicity. Still puzzling over parallelax? If I point out that our eyes, being a distance apart, employ parallelax to give a sense of depth, you will almost certainly grasp the concept.
A parsec, then, is defined as the distance subtended by one second with a base of one astronomical unit. Just for jollies, let’s point out that the distance subtended on such a basis is quite large, 206,265 AU. You can find far lengthier definitions. I know I did. Most often, though, the simplest is best.
Two curious things about the definition of the parsec I have employed. First of all, despite its name, its use in astronomy ignores the effect of parallelax since 206,265 AU is very much greater than 1 AU. We have heard this sort of argument before, when we were studying calculus. The second curious feature is a confounding one. While parsec is the preferred unit of measurement by astronomers, it is defined in terms of one of the non preferred units, the astronomical unit. Such paradoxes abound in science.
Of course, for us, the paradox is that by no stretch of the imagination, at least using my imagination, can we have any sense of what distance a single parsec is. An astronomical unit; yes, just about. And a light year, while not imaginable is, at least, comprehensible. This is a problem that popular science writers will grapple with in almost everything they write. We’ll leave them to grapple.
To return to where we started, and to bring the discussion to a close, the understanding of fiction, even the most, shall we say, difficult, is not limited to our comprehension of the text. We may not have penetrated the work to all its possible levels but we will have gained an understanding such that we can relay that understanding to others. Scientific writing, by contrast, of specialist scientific areas, putting aside papers which seek to convey data and findings, but staying with writing which seeks to convey the fundamental ideas, will frequently employ terms which are not readily explainable by the specialist, nor are they easily understood by others than those with years of training in, and knowledge of, the field. The challenge to the lay person to achieve even a modicum of understanding of such material is very great.
