Destruction and Creation

TL;DR — John Boyd’s only written essay: an eight-page argument that thinking means repeatedly breaking down old concepts and building new ones.

Dated 3 September 1976, the essay sits under Boyd’s later OODA loop and Patterns of Conflict briefings. He draws on Gödel, Heisenberg and the second law of thermodynamics to argue that any closed mental model drifts from reality, so you must keep tearing concepts apart (destructive deduction) and recombining the pieces (creative induction).

What it is: a short, dense primary text from a military strategist, often cited and rarely read. The goalsys.com host is gone; this copy is from the Wayback Machine.
