About this edition

This is an experiment in interactive reading, and in using AI to help you grow. Thus Spake Zarathustra is notoriously difficult for a modern reader; yet taken as a set of mental exercises, it is guaranteed to transform your thinking by the time you reach the end. Along the way you will have help from the companion, who is always beside the book.

The companion

Signed-in readers can talk with a companion that knows the book, its ideas and its critics, and remembers your conversations; only you can see them, on your page.

Each reader has a daily allowance for the companion, shown as a candle in its window: about 12 questions a day, renewed at midnight, US Central time. If you need more, ask the author. Paul Slusarz on LinkedIn

The thinking behind it

You can also ask the companion about the philosophy behind this edition: why books are worth this effort, and why the app is built around a companion. She draws on the author's essays on both.

The texts

English: Thomas Common's translation (1909). Polish: Wacław Berent's translation (1905). Both are in the public domain, as are the criticism and commentary in the library.
