4325. Sense in general, or general sense, is distinguished into voluntary and involuntary. Voluntary sense is proper to the cerebrum, but involuntary sense is proper to the cerebellum. In men these two kinds of general sense are conjoined, but yet are distinct. The fibers which flow forth from the cerebrum present the voluntary sense in general, and the fibers which flow from the cerebellum present the involuntary sense in general. The fibers of this double origin conjoin themselves together in the two appendices which are called the medulla oblongata and the medulla spinalis, and through these pass into the body, and shape its members, viscera, and organs. The parts which encompass the body, as the muscles and skin, and also the organs of the senses, for the most part receive fibers from the cerebrum; and hence man has sense and motion in accordance with his will. But the parts within this compass or enclosure, which are called the viscera of the body, receive fibers from the cerebellum; and consequently man has no sense of these parts, nor are they under the control of his will. From this it may in some measure appear what sense is in general, or the general voluntary sense, and the general involuntary sense. Be it known further that there must be a general in order that there may be any particular, and that the particular can in no wise come into existence and subsist without the general, and in fact that it subsists in the general; and that every particular is circumstanced according to the quality and according to the state of the general; and this is the case with sense in man, and also with motion.
