Material discovery pinpointing the location of certain functions or abilities does not nullify immaterial cause or existence. For every immaterial element or function has a causal connection or manifestation to materiality, or else immateriality would in fact be unessential. Therefore, the habit of reducing all things to material causes upon finding or locating the material cause is not sound, for the material cause is simply a manifestation of an immaterial element or function. Even if images were to be found in the brain when thought, even within the neuron, it is still the mind from which the image proceeds, and imprinted upon the brain on the neurological level.
