If we conceive all the changes in the physical world as reducible to the motion of atoms, motions generated by means of the fixed nuclear forces of those atoms, the whole of the world could thus be known by means of the natural sciences.

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

In the real life-process, willing, feeling, and thinking are only different aspects.

If there were a science of human beings it would be anthropology that aims at understanding the totality of experience through structural context.

From the perspective of mere representation, the external world always remains only a phenomenon.

What man is, only his history tells.
