Which principles underlie the four realms?

The first: spirit is still an undivided unity. The individual remains submerged in the whole. He has no right of his own.

The second: spirit knows of this unity. The individual lives it in beautiful, ethical freedom.

The third: spirit withdraws into itself, into an abstract universality. The outer world stands over against it, foreign and without spirit.

The fourth: spirit finds its truth in its inner self. It reconciles itself with the world and is at home in it. It creates its truth and knows it, as thought and as a world of laws.

Summary: There are four principles. Sinking into unity, beautiful ethical freedom, retreat into abstract inwardness. And finally the reconciliation of inner and outer.
