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 individual always realizes only one of the possibilities in its development, which could always have taken a different turning whenever it has to make an important decision.

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.

However, the sciences of society and of history retained their old subservient relation to metaphysics for a long time - well into the eighteenth century.
