Measure

Measure is the unity of quality and quantity. In measure, quantity is no longer indifferent, but constitutive for quality. Every quality has its specific quantum --- its characteristic magnitude. Examples: salt in soup (too little: bland, too much: over-salted), body temperature (37°C: healthy, 40°C: fever). Measure has leeway: within the limits, quantitative variation does not change the quality. At the turning points (nodal line of the relations of measure), quantitative change leads to a qualitative leap (water -> ice -> steam). The measureless is the state in which the old quality collapses.
