# Human Memory Already Lived Outside the Body by Samuel Butler
> "Man has now many extra-corporeal members, which are of more importance to him than a good deal of his hair, or at any rate than his whiskers. His memory goes in his pocket-book."
> **— Samuel Butler's answering writer**, *1872, Erewhon, Chapter XXV*
## Sources and Context
- **Full source:** [Samuel Butler, Erewhon, “The Book of the Machines”](https://www.gutenberg.org/cache/epub/1906/pg1906-images.html). The answering writer inside Erewhon argues that tools are extra-corporeal human members; the preceding sentence is restored from the full text so the pocket-book line has its referent. The speaker is a fictional character in Butler's novel; the author stages more than one position.
