Our meaning will perhaps be made clear by an illustration from the healing art. Confining ourselves to the simple facts, we might say correctly enough, fever and gout, as two leading forms of human disease, have their seats either in the organs and circulation of the blood, or in the system of the bones and muscles. Still it would not be inconsistent with such a statement to believe that the primary occasion or cause of both evils has a deeper and more hidden origin in some higher organ of life within the human frame, and in some derangement or disturbance of its functions. In their outward effects, however, and manifestation, these two diseases respectively seize upon these two spheres of bodily organization, and there spend themselves. And the same is true of those two intellectual diseases, rationalism and the absolute system of nature, as regards the reason and fancy. The latter are their principal seats: they form the domain wherein all the false productions of erring systems are engendered and spring up, or, in other words, the spot where the paroxysm of their internal enmity and strife comes to a complete outbreak. Of course we do not mean that these two diseases always present themselves simply and purely. In the morbid state of the intellect, as well as in the similar case of organic affection, there are numerous complications of disease which require a careful and accurate treatment. The first cause of all intellectual disease, of scientific error, or systematic infidelity, or generally of every species of a false faith, may lie still deeper, or must be traced still higher to some more remote and hidden cause. And, in truth, the primary origin of all human error is to be found in the alienation of the mind or spirit from God and His eternal light, and in its inevitable consequences--the obscuration of the soul, and the blinding, and the aberration and disorder of the senses--and especially of the higher scientific sense for truth. And in order that the senses may be gradually restored to their true state and order, and reopened--and in order that the soul be also illuminated anew, the spirit must recover its true luminous center in God. When this is once done, the whole of man’s cognitive faculty will be restored to its original state.
