How long does it take to read The Emperor's New Mind?

At 466 pages, The Emperor's New Mind is a fairly long book. Expect about 8 hours 30 minutes of reading to finish it, based on 250 words per page and an average reading speed of 230 words per minute. A fast reader will go quicker; a careful read (or reading in a second language) will take longer.

At 30 minutes a day, that is about 17 days of reading. At the median pace of Vread readers, 72 pages per reading day, it takes 7 reading days. For a book of this length (400 to 599 pages), Vread readers who finish it take a median of 5.3 days between the first and the last checkpoint (Vread Reading Barometer 2026).

In Vread, The Emperor's New Mind is split into 22 checkpoints, one every 21 pages or so. At each checkpoint, a question covers the passage you have just read: a correct answer validates the step, and your progress moves forward like a training plan.

The challenge: validate all 22 checkpoints through to the last page. No giant quiz at the end, no summary to copy out: short questions along the way that prove the book was actually read. It also works as a reading quiz to check your understanding before a test.

Also available in French on Vread.

What a checkpoint looks like

The answer is in the text: reply in the app.

This is not a question from The Emperor's New Mind: to avoid spoilers, the real questions stay in the app.

Answer in the app, one checkpoint at a time.
