I shall not dilate further on this subject; because it will, (if God grant health and permission), be treated of at large and systematically in a work, which I have many years been preparing, on the Productive Logos human and divine; with, and as the introduction to, a full commentary on the Gospel of St. John. To make myself intelligible as far as my present subject requires, it will be sufficient briefly to observe.--1. That all association demands and presupposes the existence of the thoughts and images to be associated.--2. That the hypothesis of an external world exactly correspondent to those images or modifications of our own being, which alone, according to this system, we actually behold, is as thorough idealism as Berkeley’s, inasmuch as it equally, perhaps in a more perfect degree, removes all reality and immediateness of perception, and places us in a dream-world of phantoms and spectres, the inexplicable swarm and equivocal generation of motions in our own brains.--3. That this hypothesis neither involves the explanation, nor precludes the necessity, of a mechanism and co-adequate forces in the percipient, which at the more than magic touch of the impulse from without is to create anew for itself the correspondent object. The formation of a copy is not solved by the mere pre-existence of an original; the copyist of Raffael’s Transfiguration must repeat more or less perfectly the process of Raffael. It would be easy to explain a thought from the image on the retina, and that from the geometry of light, if this very light did not present the very same difficulty. We might as rationally chant the Brahim creed of the tortoise that supported the bear, that supported the elephant, that supported the world, to the tune of “This is the house that Jack built.” The sic Deo placitum est we all admit as the sufficient cause, and the divine goodness as the sufficient reason; but an answer to the Whence and Why is no answer to the How, which alone is the physiologist’s concern. It is a sophisma pigrum, and (as Bacon hath said) the arrogance of pusillanimity, which lifts up the idol of a mortal’s fancy and commands us to fall down and worship it, as a work of divine wisdom, an ancile or palladium fallen from heaven. By the very same argument the supporters of the Ptolemaic system might have rebuffed the Newtonian, and pointing to the sky with self-complacent grin [26] have appealed to common sense, whether the sun did not move and the earth stand still.
