Der Fest-Text Jest

Author’s Note:     For this wonderful occasion, I wanted to write something that reflected my intellectual interests over the years but that also celebrated the spirit of SubStance — a space where theory and practice, critical and creative impulses coexist, and a playful ethos finds room to roam. It also obviously embodies one of my longtime passions: constraintbased writing as inspired by the Oulipo. (A preemptive footnote —a few words here about Perec are lifted from Ian Monk’s The Exeter Text.) — Paul Harris

Editors’ Note:     How quickly can you detect the constraint underlying the following text?
