Rock Logic vs. Water Logic
De Bono's distinction between the logic of fixed categories (A is A, A is not B) and the logic of flow (what does this lead to?) — and the diagnostic for why AI's rock-logic architecture produces water-logic surfaces.
Rock logic is the logic of Aristotle and the Western analytical tradition — fixed categories, binary classification, the principle of non-contradiction. A thing is either true or false, in or out, right or wrong. Rock logic builds bridges that do not fall, legal systems that distinguish guilt from innocence, and scientific frameworks that produce replicable results. Water logic is different. It deals in flow, tendency, and direction — not what a thing is, but where it leads. Anger flows to regret flows to apology flows to vulnerability flows to intimacy, none logically entailed, all connected by associative momentum. De Bono argued creativity operates in water logic and that the Western confusion of rock logic with all logic has crippled creative practice.

The distinction becomes consequential when applied to AI. Large language models are rock-logic machines that produce water-logic outputs. The computational core is
