 The most common reason for denying souls to plants, Fechner notes, is that they do not have a central nervous system. If one destroys the nerves of a human or animal, they show no signs of life. It therefore seems that plants cannot a have a soul because they have no nervous system. But here Fechner raises an interesting question: Are nerves the only possible organs to produce sensation? Nature has many means to the same end, and we should not assume that there is only one way to produce sensation. If we cut all the strings of a violin, it produces no sound; but not all instruments are stringed. We can produce sound from wind instruments. Similarly, nature might have many means of creating sensations apart from a nervous system (Nanna: 28). The fibers of plants could perform the same function as nerves.
