We distinguish between the acts of Mind, inwardly exerted--the acts, for instance, of Reason, of Memory, and of Affection--and acts of the Mind communicating through the senses with the external world. But Butler seems to me to go too far when he says, "I confess that in sensation the mind uses the body; but in reflection I have no reason to think that the mind uses the body." But, my dear friends, I, Christopher North, think, on the contrary, that the Mind uses the Brain for a thinking instrument; and that much thought fatigues the Brain, and causes an oppressive flow of the blood to the Brain, and otherwise disorders that organ. And altogether I should be exceedingly sorry to rest the Immortality of the Soul upon so doubtful an assumption as that the Brain is not, in any respect or sort, the Mind's Organ of Thinking. I see no need for so timid a sheltering of the argument. On the contrary, the simple doctrine, to my thought, is this--The Mind, as we know it, is implicated and mixed up with the Body--_throughout_--in all its ordinary actions. This corporeal frame is a system of organs, or Instruments, which the Mind employs in a thousand ways. They are its _instruments_--all of them are--and none of them is itself. What does it matter to me that there is one more organ--the Brain--for one more function--thinking? Unless the Mind were in itself a seeing thing--that is, a thing able to see--it could not use the Eye for seeing; and unless the Mind were a thinking thing, it could not use the Brain for thinking. The most intimate implication of itself with its instruments in the functions which constitute our consciousness, proves nothing in the world to me, against its essential distinctness from them, and against the possibility of its living and acting in separation from them, and when they are dissolved. So far from it, when I see that the body chills with fear, and glows with love, I am ready to call fear a cold, and love a warm passion, and to say that the Mind uses its bodily frame in fearing and in loving. All these things have to do with manifestations of my mind to itself, Now, whilst implicated in this body. Let me lift myself above imagination--or let my imagination soar and carry my reason on its wings--I leave the body to moulder, and I go sentient, volent, intelligent, whithersoever _I_ am called. TALBOYS. It seems a timidity unworthy of Butler to make the distinction. Such a distinction might be used to invalidate his whole doctrine. NORTH.
