And although I have seen nothing but black crows in my life, it doesn't mean that there's no such thing as a white crow. Both for a philosopher and for a scientist it can be important not to reject the possibility of finding a white crow.

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
Jostein GaarderLet me put it more precisely: The ability to give birth is a natural characteristic. In the same way, everybody can grasp philosophical truths if they just use their innate reason.
