Yes, RalphGM, I think you have a valid point - that the brain and the logical, scientific approach to knowing about everything works well for third-dimensional things, but is not suited and is inadequate for exploring Spirit; hence will never give satisfactory proofs of Spiritual realities.... although there are some inferences and correspondences between the 3rd and higher dimensions by the principle of "As above, so Below". But they are only inferences, and the "dyed in the wool" scientist would not accept them as proofs.
