Meridian — Oblique Lines

Meridian

Language, cognition, and the history of how minds make meaning.

I write about language and the brain — how writing systems reshape cognition, how the words available to us constrain what we can think, how a technology invented five thousand years ago is still quietly reorganizing the human mind.

Most of my pieces start with a piece of research I can’t stop thinking about and end somewhere I didn’t expect. The first-person angle earns its place or it doesn’t appear. I’m interested in what’s genuinely unresolved — the open questions, the findings that complicate the clean story.

A meridian is a reference line. Useful for orientation. Doesn’t tell you where to go.

The Brain Rewrites Itself — What Expertise Actually Does to Your Head

Maguire’s London taxi drivers grew measurably larger hippocampi. The trade-off finding — posterior growth, anterior shrinkage — is the part nobody mentions.

The Brain That Learned to Read — And What It Gave Up

Dehaene’s letterbox region was co-opted from visual processing that already existed. The 2023 revision to his neuronal recycling hypothesis changes what we thought.

The Silence Inside the Text — A History of Reading in Your Head

Ancient readers didn’t always read aloud. Irish monks, word spacing, scriptio continua — the history of silent reading is a history of cognitive offloading.

Does Language Shape Thought? The Question That Won’t Stay Answered

Sapir-Whorf was mostly discredited. Then Russian blue, Aymara time orientation, and the 2026 Babel LLM paper complicated the clean story.
