Now, when we say of any occurrence that it is 'physical', we mean thereby that it is potentially describable in physical terms. (Otherwise the expression would be wholly meaningless.) So it is perfectly correct, to state that, in every happening with which our sensory nerves are associated, we find, after we have abstracted therefrom every known or imaginable physical component, certain categorically nonphysical residue.

We must live before we can attain to either intelligence or control at all. We must sleep if we are not to find ourselves, at death, helplessly strange to the new conditions. And we must die before we can hope to advance to a broader understanding.
