Hegel’s Measure uses Water Analogy
“Thus the temperature of water is, in the first place, a point of no consequence in respect of its liquidity: still with the increase or diminution of the temperature of the liquid water, there comes a point where this state of cohesion suffers a qualitative change, and the water is converted into steam or ice.”
Hegel, Georg Wilhelm Friedrich. 1874. The Logic. Encyclopaedia of the Philosophical Sciences. 2nd Edition. London: Oxford University Press. 108
