Extensive

Hegel (logic of being, form of quantum)

Extensive magnitude is divisible, addable quantity. It consists of homogeneous parts (number, amount). Examples: length (1m + 1m = 2m), mass (5kg + 3kg = 8kg), number (3 apples). The whole is the sum of the parts. Extensive magnitude is directed outward (extension). It flips over into intensive magnitude: many small differences become degree (many molecular motions = temperature). In thermodynamics: extensive quantities scale with system size.

Origin

From Latin *extensio* (extension). Descartes: *res extensa* as the basic property of matter. Kant: extensive magnitude in the "Anticipations of Perception." Hegel: extensive/intensive as dialectical moments of the quantum.
