But DNA alone cannot explain mind-body healing. Molecular biology cannot explain why the DNA of some cells is involved in thought, and others in healing. The point is this. Some of these functions you will recognize as instincts that are connected with emotions. Molecular behavior can be completely explained within physical laws, without giving them the attribute of fear.
Fear is a vital body movement programmed into the physical body.
Some functions that separate living from non-living are a little more esoteric. Sheldrake has introduced non-local morphogenetic fields in biology whose origin is outside the physical universe. I call this behavior program-like. If there are software programs that living systems carry out, then they must have started from some idea somewhere by some programmer. So the vital body is needed.
