The owl of Minerva first begins her flight with the onset of dusk. - Georg Wilhelm Friedrich Hegel

On the stage on which we are observing it, — Universal History — Spirit displays itself in its most concrete reality.

Not only must philosophy be in agreement with our empirical knowledge of Nature, but the origin and formation of the Philosophy of Nature presupposes and is conditioned by empirical physics. However, the course of a science's origin and the preliminaries of its construction are one thing, while the science itself is another. In the latter, the former can no longer appear as the foundation of the science; here, the foundation must be the necessity of the Concept.

It may indeed be said that since Philosophy began to take a place in Germany, it has never looked so badly as at the present time — never have emptiness and shallowness overlaid it so completely, and never have they spoken and acted with such arrogance, as though all power were in their hands ! To combat the shallowness, to strive with German earnestness and honesty, to draw Philosophy out of the solitude into which it has wandered — to do such work as this we may hope that we are called by the higher spirit of our time. p. xi
