The arguments against the independent existence of the soul which Tyndall puts into the mouth of his Lucretian disciple are not difficult to answer. "You can form no picture of the soul," he says. No; and neither can we form a mental picture of love or hate, of right and wrong, or even of bodily pain and pleasure. "If localized in the body, the soul must have form." Must a pain, localized in the finger, have form? "When a leg is amputated, in which part does the soul reside?" We answer, that the soul resides in the body, with reduced power. Its instrument is less perfect than before--like a telescope which has lost a lens. "If consciousness is an essential attribute of the soul, where is the soul when consciousness ceases by the depression of the brain?" Is there any difficulty, we reply, in supposing that the soul may pass sometimes into a state of torpor, when its instrument is injured? A soul may sleep, and so be unconscious, without being dead. "The diseased brain may produce immorality: can the reason control it? If not, what is the use of the reason?" To this we answer that the soul may lose its power with a diseased body; but when furnished with another and better body, it will regain it. "If you regard the body only as an instrument, you will neglect to take care of it." Does the astronomer neglect to take care of his telescope? These answers to the Lucretian may be far from complete; but they are at least as good as the objections. The soul, no doubt, depends on the body, and cannot do its work well when the body is out of order; but does that prove it to be the _result_ of the body? If so, the same argument would prove the carpenter to be the result of his box of tools, and the organist to be the result of his organ. The organist draws sweet music from his instrument. But as his organ grows old, or is injured by the weather, or the pipes crack, and the pedals get out of order, the music becomes more and more imperfect. At last the instrument is wholly ruined, and the music wholly ceases. Is, then, the organist dead, or was he only the result of the organ? "Without phosphorus, no thought," say the materialists. True. So, "without the organ, no music." Just as in addition to the musical instrument we need a performer, so in addition to the brain we need a soul.
