"It’s in honoring this movement of mind, this tendency of thoughts to proliferate like yeast, that I find semicolons so useful. Their textbook function — to separate parts of a sentence “that need a more distinct break than a comma can signal, but that are too closely connected to be made into separate sentences” — has come to seem like a dryly beautiful little piece of psychological insight. No other piece of punctuation so compactly captures the way in which our thoughts are both liquid and solid, wave and particle. And so, far from being pretentious, semicolons can be positively democratic. To use a semicolon properly can be an act of faith. It’s a way of saying to the reader, who is already holding one bag of groceries, here, I know it’s a lot, but can you take another? And then (in the case of William James) another? And another? And one more? Which sounds, of course, dreadful, and like just the sort of discourtesy a writer ought strenuously to avoid. But the truth is that there can be something wonderful in being festooned in carefully balanced bags; there’s a kind of exquisite tension, a feeling of delicious responsibility, in being so loaded up that you seem to have half a grocery store suspended from your body."
