The One

A physicist traces monism — the idea that everything is ultimately one thing — from Parmenides and the Upanishads through to quantum entanglement and the measurement problem.

Why it’s on the list: Named in the “best history book” thread. An intellectual history of a single idea across three thousand years, which is the kind of lineage tracing Kyle collects.

Where I saw it: In Kyle’s “Books To Read” Apple Note, recovered from the reply thread to @typesfast asking “What’s the best history book you’ve read?” (June 5, 2025). The full recovered list lives on What’s the best history book… (tweet).

Filed with the author in the filename because the bare title is too generic. Page count omitted — no reliable catalog figure found.
