A thought becomes recognisable when dispersed materials enter a relation strong enough to hold. Condensation is not creation from nothing but a phase transition through which observations, memories, techniques, words and unresolved problems become temporarily coherent. CategoryEmergence names the threshold at which previously separate elements become comparable, while SensibleOpening marks the perceptual event through which their relation can finally be experienced. Duchamp's readymade, the free plan or Kekule's benzene ring show that novelty often lies less in new components than in the exact configuration that gathers familiar materials and produces consequences unavailable before their connection. The moment may appear sudden, but it is usually the visible edge of a much longer process of preparation, hesitation and comparison. Condensation should not be judged by coherence alone: stereotypes and conspiratorial explanations also compress complexity into compelling forms. A productive condensation remains reversible, preserves remainder and generates further inquiry. One must be able to return from the compact proposition to the evidence that supports it; some elements must resist complete absorption; and the relation must travel far enough to meet a contrasting case without becoming infinitely elastic. Condensation becomes formulation when the emerging relation acquires a stable public form - a name, diagram, model, sentence or image - that others can repeat, test and contest. Portability begins here, together with the politics of reduction.
