Quantum
Hegel (Logic of Being, determinate quantity)
Quantum is determinate quantity - a magnitude with a boundary (5 meters, 100 degrees). Unlike the qualitative boundary, the quantitative boundary is indifferent: more or less does not change the what. Quantum has a double structure: extensive (divisible, addable, like length) and intensive (indivisible, degree, like temperature). It stands in relation to other quanta (direct 1:2, inverse 1/x, power x²). Spurious infinity shows itself here as "always still more."
Origin
Latin "quantum" (how great, how much). In scholasticism: quantitas (magnitude as such) versus quantum (determinate magnitude). Newton: quantity as measurable magnitude. Hegel: quantum as a moment in the self-development of being.
