PART I

What Writing Is

Scientists spend enormous amounts of time writing. Many spend more time on writing than on designing experiments, gathering and analyzing data, devising proofs, or any of the other things scientists do. And yet, many scientists pay little attention to writing as a process. They think of it as a rather mechanical step in which they simply record the results of the work after they’re “done.”

This view is badly misleading. For most of us, writing is hard work, a source of stress and frustration, and so it deserves the same kind of deliberate consideration we give to experimental techniques. What is it that you’re trying to write? Why do the standard scientific forms we use have the structures, styles, and other attributes they do? What belongs in a manuscript, what doesn’t, and why? What are you thinking and doing as you sit at the keyboard writing (or, perhaps, not writing)? What’s the relationship between the writer and the reader, and how can deliberate thought about that relationship make your writing better?

The central message of this book is that all these questions can be answered, and the quality and quantity of your writing vastly increased, with attention to three points. First, most scientific writers aren’t born geniuses, but develop facility with writing by deliberately practicing the craft. Second, the goal of all scientific writing is clarity: effortless transfer of information or argument from writer to reader. Third, it’s enormously helpful for writers to think consciously about their own writing behavior. This book will explore each of these points at length. We’ll begin, though, with something fundamental but often overlooked: if you want to get better at writing, it helps to think about what writing is—by which I mean how we write, why we write that way, and how that “way” has evolved over the years to better suit our needs as writers and as readers.

ONE

On Bacon, Hobbes, and Newton, and the Selfishness of Writing Well

The Invention of Clarity

In the European early modern period (c. 1500–1750), everything was changing. The period saw the Protestant Reformation, the introduction of representative democracy, the secularization of political power, and the origins of the sovereign nation-state. It saw globalization of trade in goods and ideas, but also the subjugation of much of the world under European colonization.

Science was transforming itself right alongside religion, politics, and global economies. European curiosity cabinets (figure 1.1) were bulging with specimens from overseas exploration and trade: stones, creatures, and artifacts begging to be explained by new ideas in natural science and anthropology. Chemistry took its first steps away from alchemy and toward rational discovery. Astronomy and physics were revolutionized by painstaking observations and new instruments. Finally, the invention of the calculus gave mathematics its key place at the center of all the sciences.

But while the content of human knowledge was exploding, another, more important change was taking place. The development of modern scientific methods, professional scientists, scientific societies, and (in case you were wondering about the point of this historical excursion) modern-style scientific writing changed the way people acquired and communicated knowledge. In a sense, this was when scientists learned to write—or, more particularly, to write with the explicit goal of making their ideas available to a broad scientific community.

This was a big change. Medieval “scientists” (alchemists, for instance) generally thought of themselves as solitary workers who would penetrate nature’s secrets for their own gain. Thus, if they wrote their findings down at all, it was to claim priority or to make notes for their own use—and what they wrote was deliberately obscure or even written in code to protect their secrets from their rivals. One of the first proponents of change was Francis Bacon, who criticized this secrecy and argued instead in his 1609 essay De Sapientia Veterum that “perfection of the sciences is to be looked for not from the swiftness or ability of any one inquirer, but from a succession.” In a novel, New Atlantis (1627), Bacon described a fictitious research-institute-cum-scientific-society he called “Salomon’s House”—which he clearly intended as a proposal for how science should work. In Salomon’s House, research progressed because scientists communicated and collaborated with one another. (Bacon may well have been inspired by Islamic science of the eighth and ninth centuries, which had flourished, collaboratively, under the Abbasid caliphs Harun al-Rashid and Abu al-Mamun [Lyons 2009].)

Bacon’s concept of Salomon’s House inspired the creation of the Royal Society of London in 1660. Its founders extended his ideas about communication among collaborating scientists to communication with a broad scientific community and even with the curious public. One of those founders was Robert Boyle, who essentially invented a new form of writing: the scientific report, which described the methods and results of an experiment (Pérez-Ramos 1996). Another was Thomas Hobbes, who wrote in the preface to his 1655 work De Corpore, “I distinguish the most common notions by accurate definition, for the avoiding of confusion and obscurity”—a goal that seems routine today, but would have been outrageously unconventional in Hobbes’s time. The founding of the Society brought with it the first modern scientific journal, Philosophical Transactions of the Royal Society, which printed scientific reports of the kind pioneered by Boyle, written in the clear language advocated by Hobbes. Just a dozen years later, Thomas Sprat described the organization’s rhetorical philosophy as

a constant resolution, to reject all the amplifications, digressions, and swellings of style … a close, naked, natural way of speaking; positive expressions, clear sense, a native easiness: bringing all things as near the mathematical plainness, as they can. (Sprat 1667, 113).¹

All this may seem obvious from our modern vantage point, but the transition from medieval secrecy through Bacon and Hobbes to the “clear sense [and] native easiness” of Sprat’s Royal Society was revolutionary. Without this tectonic shift in how science was reported, modern science couldn’t be done. The inventions of the calculus, the telescope, the microscope, and the inductive method (all between 1590 and 1630) were certainly important, but they’re all outweighed in importance by the idea of describing one’s scientific thinking clearly, for all to read.

Of course, no revolution lacks holdouts, and the revolution in scientific communication had a curious one: the famously cranky Isaac Newton, for whom publication remained largely about ensuring credit for his work. For example, he drafted his On Analysis by Infinite Series in 1669 in response to Nicholas Mercator’s Logorithmotechnia, which Newton worried would undermine his claim of first discovery for some key insights underlying the calculus. Newton allowed only limited circulation of the manuscript within the Royal Society, and only agreed to open publication in 1711. More famously, he deliberately made his masterwork Principia Mathematica—and especially its third volume, De mundi systemate—difficult to read. Newton had originally written De mundi systemate in plain language to be accessible to readers (Westfall 1980, 459), but changed his mind and rewrote it as series of propositions, derivations, lemmas, and proofs comprehensible only to accomplished mathematicians. He left little doubt of his intent, telling his friend William Derham that “in order to avoid being baited by little smatterers in mathematics, he [Newton] designedly made his Principia abstruse” (Derham 1733). That is, Newton wrote to impede communication with other scientists, not to facilitate it! Of course, by then Newton was a superstar, and readers were likely to put in whatever effort was needed to penetrate the fog. Those readers could spare the effort, too, as the flow of published works competing for scientists’ attention was still little more than a trickle. This, too, would change.

Clarity and “Telepathy” in the Modern Era

Bacon, Hobbes, Sprat, and others of their time were taking the first steps toward what became, by the twentieth century, a consensus that the goal of most writing is clear communication. The best-known reflection of this is probably Strunk and White’s The Elements of Style, first published in 1920. White described Strunk’s opinion that the typical reader was “floundering in a swamp” and that it was “the duty of anyone trying to write English to drain this swamp quickly and get [the reader] up on dry ground, or at least throw [down] a rope” (Strunk and White 1972, xii). However forceful Strunk’s pleading, though, the argument for clarity has its purest expression in Stephen King’s On Writing: A Memoir of the Craft. King’s chapter “What Writing Is” opens with the simple declaration: “Telepathy, of course” (King 2000, 95).

The word “telepathy” may seem chosen for humor, but in scientific writing your goal should always be communication so crystal-clear that it feels to the reader like direct transmission to their brain from yours. You’re writing because you have some information to convey, and your goal should be for the reader to receive that information without even being aware of the process. As Nathaniel Hawthorne put it, “The greatest possible merit of style is … to make the words absolutely disappear into the thought” (letter to E. A. Duyckinck, 27 Apr. 1851, quoted in Van Doren [1949], 267). If the reader pauses to question your word choice or needs to squint to distinguish between two lines on a graph, then you’ve joined a battle you don’t want to be in: what you’re trying to say is fighting for the reader’s attention with the way you’re saying it.

At this point, you might be a little skeptical. After all, it’s a popular belief that people who use big words and complicated sentences seem more intelligent. Most research, though, finds the opposite: people ascribe higher intelligence to writers who (and higher quality to texts that) use smaller words and simpler sentences (e.g., Oppenheimer 2006). But even if the popular belief held and difficult prose did make you seem smarter, this would only help if people actually read it. This brings me to my next point.

The Selfishness of Writing Well

Achieving telepathic writing is hard work (chapter 2). I’ve spent many hundreds of hours crafting pieces of writing that I hoped might achieve crystal clarity, and in this book I’ll urge you to do the same. Those were hundreds of hours I could have spent doing more experiments, or drinking beer with friends, or even just walking along the water’s edge skipping stones. So why invest the time and effort in writing well?

It might seem that working to make your writing clear is an act of generosity toward the reader—the impression left by Strunk’s metaphor of throwing the reader a rescue line. Or it might seem an act of generosity toward the progress of science. This was the argument made by Bacon, Sprat, and others in the 1600s; in this view, Newton was selfish in withholding his written work and writing for opacity.

There’s no question that writing well serves both the reader and the progress of science. But the evolution of science and its spectacular growth since Newton’s time have changed the incentives for writing well. In the 1680s, Newton had t...
