to nature in general, is it unreasonable to ask what did the human develop in adjustment to? Certainly something! What this something is we surely know. The faculty of perceiving truth develops by adjustment to Truth, the sense of purity to Purity, charity to Charity, righteousness to Righteousness, godliness to Godliness, humanity to Humanity.
We have but to consider the spiritual world as real as nature, and capable of spiritual powers as nature is of natural powers, and to think of the Divine Human of God filling the spiritual world full of human power as the sun fills nature with sun-powers, to have a rational, tangible basis for progressive study.
Should this seem to be a statement too large for human grasp, let it be said that we do not have to enter strange territory to confirm this. We are not required to believe anything
