twofoldness

When we conceive of our idea of soleness as a frame there is nothing which can enter into this, nothing which retains twofoldness can enter into this concept of unity.

This twofoldness finds a curious illustration in the sub-titles of several of his books.

The solution appeared to him perfect, according to his study and analysis of the problem—the twofoldness that he found in man, of divine dignity on the one hand, and frivolous, sensual degradation on the other. 

Deeper than this golden mean, however, runs the idea here; the dialectic of existence, the twofoldness which must be made one, the higher synthesis over all analysis are dimly intimated in the marvelous tale.

I confess that till the light of the twofoldness of the Christian Church dawned on my mind, the study of the history and literature of the Church during the first three or four centuries infected me with a spirit of doubt and disgust which required a frequent recurrence to the writings of John and Paul to preserve me whole in the Faith.
