Printing: An Essay by William Morris & Emery Walker
The pattern
This still is filed under Craft-argument book.
Define
A book or manual that sells a method by arguing it. Chapters as proof, not as decoration around a product.
Mechanism
Authority by treatise. The reader who accepts the argument has already accepted the seller as teacher.
Verdict
We can teach a craft in public and the teaching is the funnel.
Why it works
The argument is carried by the artefact more than by the sentences: the essay attacks narrowed letters, wide interlinear spacing, padded paper and ornament that is unrelated to the page, and the reader is looking at a page that does the opposite of each charge while the charge is being made. Morris and Walker also reframe beauty as costing nothing, which removes the only real objection a commercial printer has, then anchor every claim to a dated book anyone can check rather than to taste. The one concrete everyday example, straining to tell a 5 from an 8 in Bradshaw's railway guide, moves the complaint from connoisseurship to a reader's practical annoyance.
Steal this when
You are arguing for a standard of craft to people who believe the better version costs more. Kill the cost objection first, evidence the claim with dated named examples rather than taste, and make the piece itself an example of the standard so the medium settles the argument.
