Unity in Nonfiction: What, Why, How?

Open a book about the craft of nonfiction and you’ll likely find advice on creating unity in your writing. In his classic On Writing Well, William Zinsser called unity “the anchor of good writing.” Unity in nonfiction means the writing is cohesive and coherent, and the parts create a meaningful whole. We look for unity in art, music, décor, and fashion, too. Imagine seeing a lime-green molded plastic chair in a room full of early American furnishings. And what if Audrey Hepburn had worn metallic platform sandals instead of simple black pumps with her “little black dress” in the film Breakfast at Tiffany’s?

Unity in Nonfiction What, Why, How QUOTEWhile reading nonfiction, we expect the author to present things in an organized, purposeful way that helps us make sense of the topic. Without unity, it’s difficult to understand what the author intended to say, or how bits of information fit together. As Zinsser writes, unity “keeps the reader from straggling off in all directions” and reassures them “that all is well at the helm.” Readers experience a sense of harmony when the writing has unity in content, style, and tone.

Unity of Content

This process starts with choosing a topic and focusing on a manageable, meaningful aspect of that topic. A clear focus can help with the research and planning. Then we must decide what material to include and what to leave out.

Suppose you want to convince readers that organic produce is healthier to eat than conventionally grown foods? This is your thesis, or slant. Which of these subtopics doesn’t belong? (1) types of pesticides used in growing produce (2) residues of pesticides and fungicides found on conventionally grown produce (3) effects of pesticides in the body (4) how pesticides affect waterways (5) research comparing nutrient content in organic vs. conventionally grown produce.

Although #4 is important, it does not support your main point. Readers would feel a sense of disunity when they encountered such a shift and would likely wonder “Why did the author include this?” Similar issues can occur within paragraphs. For instance, if you were discussing the nutrient content in produce, a sentence about the man who first isolated Vitamin C in a lab creates disunity.

So, when it comes to content, author Gary Provost advises, “To achieve unity in your writing you must leave out anything that doesn’t belong there, no matter how witty, poetic, or profound it is.”

07-11-23 Unity in Nonfiction What, Why, How TRANSITION CANVAAs you present your chosen material, don’t forget transitions. They help to unify material by providing “bridges” and connections. Effective transitions help writing flow well from one idea, paragraph, and chapter to the next. We can use them to ease changes in subtopic, time, and place, and when making contrasts and comparisons, giving examples, and showing consequences. Example: If your previous paragraph discussed the dangers of exploring a cave, your next paragraph, on safety measures, might begin this way:

Considering these dangers, how can you prepare and take precautions to stay safe while you’re exploring?

Transitions can also help readers make a shift in mood. For instance, if your previous paragraphs described a tragic disaster, your next paragraph might start this way:

Even amidst loss and destruction, people find signs of hope, sometimes through the kindness of strangers.

Unity of Style

Along with unity in what you write, aim for unity in how you write it—your style. Perhaps all of your nonfiction writing displays a similar style, or maybe you change your style, depending on your topic. Either approach is fine; just stick with one per project. Your writing might be casual and conversational, with short sentences, contractions, and everyday language, or more formal, with longer sentences, no fragments or contractions, and complex words. Your use of punctuation also contributes to style.

Shifts in style can sound as if another author jumped in to write part of your article or book. Suppose you started with an amusing first-person anecdote using casual language and short, breezy sentences to describe your first job working in a hospital. Readers would feel a jolt if you went on to write this:

Unity in Nonfiction What, Why, How UNITY CANVAEvery year, hospital emergency rooms in the United States confront an increasing number of drug overdose cases, and the number of deaths from such cases exceeded 100,000 in 2021. Opioids, primarily fentanyl, were responsible for approximately 75 percent of these deaths.

This sober, more formal paragraph injects disunity in both style and tone.

Unity of Tone

Once you know what you will say and the effect you want to create, choose a suitable tone. Will it be serious, light-hearted, or in between? Knowing how you feel about your subject matter can help you maintain unity of tone. Will your attitude be objective, personally involved, amused, concerned, critical, admiring, skeptical, conspiratorial, or amazed, for example?

How will you address your reader—more like a participant or an observer? Perhaps you will talk to them directly, using second-person, as I’ve done in this blog. Or you might use a more impersonal, observational, academic tone.

Staying On Course

As William Zinsser noted, the author is “at the helm,” responsible for keeping things on course. Think about unity in nonfiction as you write and revise:

  • Does each idea and paragraph belong?
  • Does each sentence in the paragraph relate clearly to its main topic?
  • Did you connect facts and ideas?
  • Did you use effective transitions to help readers move smoothly through the material?
  • Are the style and the tone consistent?

Gary Provost sums it up this way: “Everything you write should look as if it was written at one time, by one person, with one purpose, using one language.”
