"...If emergence is the whole truth, it implies that mental states are present in the organism as a whole, or its central nervous system, without any grounding in the elements that constitute the organism, expect for the physical character of those elements that permits them to be arranged in the complex form that, according to the higher-level theory, connects the physical with the mental. That such a purely physical elements, when combined in a certain way, should necessarily produce a state of the whole that is not constituted of the properties and relations of the physical parts still seems like magic even if the higher-order psychophysical dependencies are quite systematic..."
