The existence of inherent limits of experience in no way settles the question about the subordination of facts of the human world to our knowledge of matter.

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

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

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.

What man is, only his history tells.

All science is experiential; but all experience must be related back to and derives its its validity from the conditions and context of consciousness in which it arises, i.e., the totality of our nature.

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.
