Imagination and Spirit

Some people talk about spiritual things, the spirit world, and so forth. Some people say all this is imaginary, as if that is a bad thing. Some extol imagination. Some reduce thought, feeling, imagination to the firing of synapses and the complex functioning of neural nodes and brain chemistry. To me, the reductionists don't have an explanation any more convincing than the most far out spiritists. I believe imagination and spirit are the same thing, differently conceived. A great work of art or music or mathematics -- of the spirit or the imagination? I say the same thing. Quantum mechanics is as much imagined as "real." The "Big Bang" is imagined in the form of mathematical models. We are like the people in Plato's Cave, seeing shadows, except that I don't think there are "ideal forms."
