The knife of historical relativism... which has cut to pieces all metaphysics and religion must also bring about healing.

The sciences which take socio-historical reality as their subject matter are seeking, more intensively than ever before, their systematic relations to one another and to their foundation.

The individual always realizes only one of the possibilities in his development, which could always have taken a different turning whenever he had to make an important decision.

On the other hand, for the whole human being who wills, feels, and represents, external reality is given simultaneously and with as much certitude as his own self.

Any theory intended to describe and analyze socio-historical reality cannot restrict itself to the human spirit and disregard the totality of human nature.

Ancient metaphysics underwent many changes at the hands of medieval thinkers who brought it in line with the dominant religious and theological movements of their day.

No real blood flows in the veins of the knowing subject constructed by Locke, Hume, and Kant, but rather the diluted extract of reason as a mere activity of thought.
