I will now consider the possibility of indivisible particles. These particles may be analogous to the atoms of Democritus and the monads of Leibniz. The indivisible particle must be dimensionless. If the particle contains any number of dimensions other than zero, then it is divisible. The question arises is there such a thing as dimensionless matter? When one cuts a piece of matter one can look closer at a piece of the cut matter and cut the matter again. This process would go on forever. Matter by definition contains dimensions and therefore will always be divisible. Therefore, the indivisible particle must not be material. The indivisible particle must be something like Leibniz’s monad. If such spiritual substances exist, they would have to be dimensionless to be an indivisible particle. Suppose that physics finally reduces matter to one particle, suppose the particle is called a monad. The question would arise, what is this particle. The answer would most likely be pure energy. The question what is pure energy would arise. No matter how much scientists reduce matter to its most fundamental components the question will remain what is energy. Some think energy is electromagnetic waves. Electrons must exist for electricity and electromagnetic waves to exist and the question would arise what is an electron. Even if an electron was a bundle of pure energy the question would remain what is energy. The question would eventually arise why does electricity behave the way it does. The answer would be because opposite charges attract. The question arises why do they attract. Scientists do not explain why things are the way they are but explains how things are the way they are. Science does not explain what things are at their irreducible level. Scientists don’t know ultimately why energy behaves the way it does but use the term to describe the phenomena they perceive. They manipulate energy but do not know why energy behaves the way it does. As all matter is reduced to pure energy, pure energy is simply what is or what has existence in philosophical terms. Energy is the spiritual love which all things are.
