When is the dialectical method used?
Dialectic
As an example, Hegel mentions the states of aggregation of water: "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".[36] As other examples Hegel mentions the reaching of a point where a single additional grain makes a heap of wheat; or where the bald tail is produced, if we continue plucking out single hairs.
