‘The state of disease proves also the plurality of the organs. For how is it possible to combine partial insanities with the unity of the brain? A chemist was a madman in everything but chemistry. An embroiderer in her fits, and in the midst of the greatest absurdities, calculated perfectly how much stuff was necessary to such or such a piece of work.’ Page 219. Does our author mean that there is an organ of chemistry, and an organ for embroidery? King Ferdinand would be a good subject to ascertain this last observation upon. If I could catch him, I should be disposed to try. I would not let him go, like the Cortes. ‘The external apparatus of the nerves of the five senses are said to be different, because they receive different impressions: but how is it possible that different impressions should be transmitted to the brain by the same nerves? How can the impressions of light be propagated by the auditory nerve?’ Page 227. We only know that they are not. But how, we might ask, can the different impressions of sight—as red, yellow, blue—be transmitted by the same nerve? ‘Plattner made the following objection:—“A musician plays with his fingers on all instruments; why should not the soul manifest all its operations by means of one and the same organ?” This observation is rather for than against the plurality of the organs. First, there are ten fingers which play: moreover, the instruments present different chords or holes. We admit only one organ for music; and all kinds of music are produced by this organ. Hence, this assertion of Plattner does not invalidate our theory.’ Page 230. But it does though, unless you could show that a musician can play only as many tunes as he has fingers, on the same kind of instrument. Dr. Spurzheim contends elsewhere that one organ can perform only one function, and brings as a proof of the plurality of the organs the alternate action and rest of the body and mind. But if the same organ cannot undergo a different state, how can it rest? There must then be an organ of action and an organ of rest, an organ to do something and an organ to do nothing! Very fine and clear all this. The following passages seem to bear closest upon the general question, and I shall apply myself to answer them as well as I can.
