When you realize there is something you don't understand, then you're generally on the right path to understanding all kinds of things.
Jostein GaarderHistory is one long chain of reflections. Hegel also indicated certain rules that apply for this chain of reflections. Anyone studying history in depth will observe that a thought is usually proposed on the basis of other, previously proposed thoughts. But as soon as one thought is proposed, it will be contradicted by another. A tension arises between these two opposite ways of thinking. But the tension is resolved by the proposal of a third thought which accommodates the best of both points of view. Hegel calls this a dialectic process
