The existence of the universe is opposed to the law of a sufficient cause; infinity and eternity are incomprehensible to our conceptions, which are confined to space and time.
The essential nature of force and volition remains inexplicable.

We recognize only a subjectively qualified phenomenon in the world; the impelling forces and the real nature of things are withdrawn from our understanding.

A systematic explanation of the universe is quite impossible from the human standpoint.

So much seems clear--although no demonstrable certainty attaches to this theory--that spiritual laws beyond the comprehension of us men govern the world according to a conscious plan of development in the revolving cycles of a perpetual change.

Even the gradual evolution of mankind seems ruled by a hidden moral law.
