noumenon

Humanity is ever seeking the Reality—the Noumenon, which we intuitively postulate as behind the phenomena of Nature.

At the end of the chain of phenomena the theist makes a mighty jump and gains the noumenon.

The outward fact is called the Phenomenon, and the corresponding inward principle is called the Noumenon.

It is a noumenon and belongs properly to the unknowable—that is to say, according to the sense in which it is understood.

The garden held a small temple consecrated to the Noumenon beyond phenomena.
