Have you ever seen a scale model of an atom? If I drew one on an 8.5x11 sheet of paper, it would consist of a tiny dot at the center, representing the nucleus, and an appropriate number of other tiny dots, smaller than could be seen by the naked eye, representing the electrons. All of these infinitesimally tiny dots would be made up of smaller particles, called quarks, or whatever. (Hey, I'm no scientist.)
The physical sciences, all the reality discernable by our five senses, is the science of those tiny dots.
Christian Science is the science of all the rest of it.
There is no overlap between the two sciences (PS & CS, for short). The realm of one is completely independent of the realm of the other. And we each experience life in the science where we invest our attention, in the proportion that we invest.
The CS science is the realm of Spirit, of infinite Mind. In this science, this substance or reality, there is no gender. There is no body. There is no death. This substance is the same throughout all space; there is no place you can go to escape it. We all live inside this substance-space of Spirit. The science that Mary Baker Eddy developed states that substance is Mind; that "all is Mind." The PS science is the realm of the earth, of mortals, of death, and it occupies only a relatively tiny, very limited existence.
One of these must be superior to the other in power and effect; and that one is the realm of Spirit, because it is the one that can influence the other. Nothing within the power or realm of PS can affect that "empty" space at all. On the other hand, the realm of PS is completely mutable. Experiments such as Schrodinger's Cat demonstrate the paradox of the physical sciences and senses. In his book, The Self-Aware Universe, Amit Goswami relates an experiment that showed a particle in two places at the same time – until it was observed, at which point it became solid in one place. (I'm relating this from memory, so if I get it wrong, my apologies to Mr. Goswami – and my readers.) Even the existence of life is a conundrum in the physical sciences, because life can't be replicated, yet it is.
Mr. Goswami comes at this situation from a different angle than Mary Baker Eddy, but comes to some remarkably similar conclusions. "Marshalling evidence from recent research in cognitive psychology, biology, parapsychology and quantum physics, and leaning heavily on the ancient mystical traditions of the world, Goswami is building a case for a new paradigm that he calls "monistic idealism," the view that consciousness, not matter, is the foundation of everything that is." [emphasis mine] Mr. Goswami reaches this conclusion from his search into cognitive psychology, biology, and quantum physics; Mrs. Eddy reached what seems to me to be an identical conclusion solely by reading the Bible and studying the works of Jesus and the prophets.
Because the foundation of reality is consciousness (or Mind), not matter, our thought creates our reality.
My problem with Christian Science is, first, that it is presented to the world as a religion, rather than as a science. And second, that the literature of Christian Science is written in the language of patriarchy and judgment. This is understandable in Mrs. Eddy's case, given the culture in which she lived; but I find it disturbing in the literature which is being written today. I find it distracting, as I am constantly interpreting the language as I read, seeking the truth hidden within a very inadequate language.
Despite that challenge, I also find it fascinating. The power of consciousness, of Mind, has barely been unleashed upon a very malleable matter. Imagine what it can do to an oil slick.
