April 18

One of the strangest things witnessed is that the materialists are proud of their natural proclivities. They state, that which is sensible or tangible is worthy of credence, but that which is not within the realm of the sense perceptions is unreasonable. By their own statements they are captives of the senses. Of the spiritual world they are uninformed: of the Divine Kingdom they are unaware; of the Divine bestowal they are unconscious. If this be a virtue, the animal has attained to a superlative degree, for the animal is absolutely unaware of and not at all in touch with the spiritual realm.
