"As it is claimed to be unphilosophical to inquire into first causes, scientists now occupy themselves with considering their physical effects. The field of scientific investigation is therefore bounded by physical nature. When once its limits are reached, enquiry must stop, and their work be recommenced. With all due respect to our learned men, they are like the squirrel upon its revolving wheel, for they are doomed to turn their "matter" over and over again. Science is a mighty potency, and it is not for us pigmies to question her. But the "scientists" are not themselves science embodied any more than the men of our planet are the planet itself. We have neither the right to demand, nor power to compel our "modern-day philosopher" to accept without challenge a geographical description of the dark side of the moon. But, if in some lunar cataclysm one of her inhabitants should be hurled thence into the attraction of our atmosphere, and land, safe and sound, at Dr. Carpenter's door, he would be indictable as recreant to professional duty if he should fail to set the physical problem at rest. For a man of science to refuse an opportunity to investigate any new phenomenon, whether it comes to him in the shape of a man from the moon, or a ghost from the Eddy homestead, is alike reprehensible.
