The utmost that can be said with any show of reason is that the imaging in our consciousness of external objects does not give an actual representation of them. This is required by the theory of Hylo-Idealism, which goes still further, however, and declares that the universe does not exist as we know it. It seems to us that this view is not consistent with even the principles of Hylo-Idealism. Dr. Lewins specially points out that this system "in no sense denies the objective, but only contends for _identity_ of object and subject, proved as it is by natural Realism itself, from the doctrine of _molecular metamorphosis_, which shows the Ego continually undergoing transubstantiation with the 'Non-Ego,' and _vice versâ_, so far as to form _one_ indivisible organism." He compares the Ego and the Non-Ego, that is, subject and object, or our bodies and the "external universe," to a porous vessel of ice, filled with water, immersed in an infinite ocean. "What is within and without, and the septum that seems to divide the two, are all three consubstantial or identical." If they are identical, however, they must perfectly respond to each other, which would not be the case if the object in the mind did not give a true representation of the objects in external nature. Otherwise the identity of subject and object can be predicated, on the condition only of abolishing the "external universe," and affirming of it, as Dr. Lewins affirms of the stars, "What you see is a vision, or organic function, of your own _sensifacient_ organism."
