How to fix one of the most common writing errors.
More Comma Splice Examples
Let's take one more of Scott's mangled sentences and see if we can fix it!
This one is from page 29, where he's explaining how one of the characters lured in investors for his evil plan.
They were getting it, he had them. (wrong)
The period definitely works: They were getting it. He had them.
The semicolon works because the two clauses are related: They were getting it; he had them.
And in this case we can add a coordinating conjunction to fix the problem too: They were getting it, and he had them.
Comma Splice Summary
So, I hope you get it! Commas aren't meant to join main clauses all by themselves; to force them into that role is to perpetrate a comma splice. That's bad, but it's easy to fix.
You, Sir, Are no Cormac McCarthy
Finally, another thing that's interesting is that the example sentences I used aren't in Ancestor anymore. Scott's writing has improved over the last three years, he reworked the book, and it probably had more extensive editing from Crown than it did with his initial small publisher. All the comma splices have been fixed.
The change highlights an interesting point about punctuation and writing in general that sometimes comes up. People will argue that authors should be allowed to make stylistic choices about writing and include comma splices or whatever quirks they want as a matter of art. They'll point to best-sellers such as E. E. Cummings who used all lowercase letters or Cormac McCarthy who is known to use as little punctuation as possible, often avoiding commas, apostrophes and quotation marks.
Occasionally, someone brilliant intentionally bucks the rules and still succeeds, but it's much more common for writers to have consistent errors like comma splices in their manuscripts not because they are brilliant renegades, but because they actually don't know the rules.
I've talked to many editors who do look at the grammar and usage in manuscripts and don't look kindly on errors. Unless you want to make it more difficult to get your ideas across to editors and readers, stick with traditional punctuation.
