This discussion goes on in all philosophies, in some form or other. Even in the most modern philosophies you find the same discussion arising. There are two parties. One says that there is no soul, that the idea of soul is a delusion produced by the repeated transit of particles or matter, bringing about the combination which you call the body or brain; that the impression of freedom is the result of the vibrations and motions and continuous transit of these particles. There were Buddhistic sects who held the same view and illustrated it by this example: If young take a torch and whirl it round rapidly, there will be a circle of light. That circle does not really exist, because the torch is changing place every moment. We are but bundles of little particles, which in their rapid whirling produce the delusion of a permanent soul. The other party states that in the rapid succession of thought, matter occurs as a delusion, and does not really exist. So we see one side claiming that spirit is a delusion and the other, that matter is a delusion. Which side will you take? Of course, we will take the spirit and deny matter. The arguments are similar for both, only on the spirit side the argument is little stronger. For nobody has ever seen what matter is. We can only feel ourselves. I never knew a man who could feel matter outside of himself.
