This book investigates Design with NOR, the title of the yet unpublished 1961 typescript by Spencer Brown. The typescript formed through the author's experiences as technical engineer and developer of a new form of switching algebra for Mullard Equipment Ltd., a British manufacturer of electronic components, and is published here for the first time.

Related essays contextualise the typescript drawing on a variety backgrounds from mathematics and engineering to philosophy and sociology, and thus invite readers to a reverse-engineering of both the form and its laws.
