Did David Hume Split Literature from Philosophy?


Have you ever wondered when philosophy stopped sounding like a lively story and started reading like a lab report? Welcome, friends of FreeAstroScience.com. Today we trace a quiet revolution that changed how we think and write about morals. Stay with us to the end—we promise a clear path through the names, dates, and ideas, and one solid “aha” moment.

What was the “character sketch,” and why did it matter?

Before moral philosophy went full “anatomy of the mind,” writers taught ethics with character sketches—short, vivid portraits of social types. Think of “the kind of person who…”. An incel. An intellectual. A mansplainer. We recognize the type by their habits, tone, and tells. It’s punchy. It’s memorable. It sticks.

This form goes back to Theophrastus, Aristotle’s gifted student. In Characters, he defined 30 everyday vices—Bad Timing, Absentmindedness, Idle Chatter—by showing them in action. No deep theory. Just crisp scenes that let us see a vice at work. The Man with Bad Timing croons love songs when his girlfriend has a fever. The Absentminded Man nods off at the theater and wakes up alone. Ordinary foibles, drawn with comic precision.

The point: description teaches. By meeting the type, we grasp the idea.


How did this literary tool become philosophy?

Renaissance and early-modern readers turned these sketches into moral instruction. After a 1430s Latin translation, editors and patrons pitched Theophrastus as a public good—useful in courts, churches, and even politics. Some thought sketching vices could calm social unrest by teaching through bad examples. It wasn’t fluff; it was civic training.

Then came Isaac Casaubon, a philological powerhouse. After two decades of work and three editions, he argued character-writing was a third way to do moral philosophy—between reasoned arguments and general advice. It was vivid like poetry and instructive like philosophy. A genuine bridge.

The tradition kept evolving:

  • Joseph Hall adapted the genre for Christian morals (1608).
  • Jean de La Bruyère turned it into a French bestseller, translating Theophrastus and sketching modern types—tax collectors, lawyers, the rich and the poor. Different classes, different gestures, different morals.
  • Joseph Addison’s Spectator popularized the technique for a coffeehouse public—Mr Spectator himself is a character sketch.

By the early 1700s, readers could learn virtue and vice by seeing them embodied. It felt practical, human, and social.

What did Hume change in 1748?

In 1748, David Hume redrew the map. In An Enquiry Concerning Human Understanding, he says there are two main ways to do moral philosophy: the “easy and obvious” and the “accurate and abstract.” Not three. Two. The “third way” of Casaubon disappears.

  • Easy & obvious: Paint virtue in “amiable colours,” borrow from poetry, pick striking episodes from common life, set opposite characters in bright contrast. (That’s the character-sketch playbook.) Hume files Cicero, La Bruyère, and Addison here—the crowd-pleasers.
  • Accurate & abstract: Start from particular cases, climb to general principles, and search for the “original principles” that bound human curiosity. That’s the anatomist’s bench, closer to Aristotle, Malebranche, Locke.

Yet Hume doesn’t pick a side; he tries to blend them. Like a painter who must know anatomy, he wants style and structure—readable prose guided by deep principles, bounded by experience.

Here’s the split, made visible:

Method What it does Signature move Representative names
Easy & Obvious Moves hearts via taste and sentiment Vivid characters, lively contrasts Cicero, La Bruyère, Addison
Accurate & Abstract Shapes understanding via first principles From cases to general principles Aristotle, Malebranche, Locke

Hume’s own project: take clarity and charm from the first, truth-seeking rigor from the second. :contentReference[oaicite:11]{index=11}

To see the method in action, compare two Hume texts from this phase. In “Of National Characters,” he doesn’t sketch a Frenchman or an Italian as types. He interrogates the principle behind national character. He hunts causes, not caricatures. In the 1751 Enquiry Concerning the Principles of Morals, his dialogue worries about the uncertainty of our judgments of character and urges a standard found by examining first principles.

Aha: when we stop painting the surface and start probing the springs, literature and philosophy begin to part ways.


When did the rivers finally diverge?

Hume’s scheme arrived at a transitional moment in the very concept of “literature.” The lively, painterly moral writing—opposite characters, scene, and social type—flowed into fiction and criticism. Philosophy kept the lab coat: syllabi favor Locke over Addison. The rivers, the Rhine and the Rhone, share a mountain but run to different seas.

A compact timeline helps:

When What happened Why it matters
4th c. BCE Theophrastus writes Characters (30 vices) Prototype of the character sketch
1430s First Latin translation Sketched vices become public ethics
1525+ Humanists use sketches for social reform Teach by bad example
1608 Joseph Hall’s English “charactery” Virtues and vices, Christian frame
Late 1600s La Bruyère’s best-selling adaptation Modern types, sociological detail
1748–1751 Hume’s Enquiries Two methods, blended—but the split sticks

Can description still count as knowledge—today?

Two lessons feel fresh.

  1. Some concepts need a face. To grasp “absentmindedness,” we don’t just want a definition; we want a person. A sketch turns fog into form. Even Hume’s opponents would concede: examples do cognitive work.

We can even write a tiny formula for the habit of generalization:

Principle = f ( observations )

Hume wants the function and the principle. The character sketch supplies the observations. Both are useful; the trick is balance.

  1. Naming a type can nudge behavior. Calling someone a “hoarder” or a “mansplainer” aims at change, not essence. It’s moral instruction by social mirror, not a stereotype carved in stone. That’s an old Theophrastan hope, updated for our feeds.

How do we use this wisely (and kindly)?

  • Describe to clarify, not to box in. Use types to illuminate, then invite growth.
  • Ask for principles after portraits. Once a sketch clicks, investigate causes.
  • Prefer revisable labels. Focus on habits, not identities.
  • Remember the audience. In public writing, sketches teach best when they’re fair, concrete, and open-ended.

So…did Hume really split them?

He didn’t slam a door; he redrew a map. In 1748 he framed ethics as two styles and built a bridge between them. The traffic, however, drifted: literature kept the lively types; philosophy kept the principles. The best work, in our view, still walks the bridge—clear prose with grip, plus careful inquiry with spine.

At FreeAstroScience.com, we write for readers who like both. We simplify without dumbing down. We believe in staying awake to how minds work, how stories teach, and how principles guide. Never switch off your mind; the sleep of reason breeds monsters. And when you need to understand a tricky idea, don’t be afraid to sketch a person first.


Conclusion

We followed a genre from Theophrastus’ comic vices to Hume’s careful principles. We saw how a short sketch can teach a big idea. We watched literature and philosophy take different roads—and learned what we can still borrow from both. As you read, write, and argue, try pairing a crisp portrait with a curious question about causes. That’s where understanding lives.
