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.

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

A knowledge of the forces that rule society, of the causes that have produced its upheavals, and of society's resources for promoting healthy progress has become of vital concern to our civilization.

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

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

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.
