Marilynne Robinson's meditation on the power and glory of the human soul is worth reading and re-reading. The wonder, the glory and the majesty of it all has been lost as modern culture has become imprisoned in its materialist caverns.
Modern discourse is not really comfortable with the word "soul," and in my opinion the loss of the word has been disabling, not only to religion but to literature and political thought and to every humane pursuit. In contemporary religious circles, souls, if they are mentioned at all, tend to be spoken of as saved or lost, having answered some set of divine expectations or failed to answer them, having arrived at some crucial realization or failed to arrive at it.
So the soul, the masterpiece of creation, is more or less reduced to a token signifying cosmic acceptance or rejection, having little or nothing to do with that miraculous thing, the felt experience of life, except insofar as life offers distractions or temptations.
Having read recently that there are more neurons in the human brain than there are stars in the Milky Way,
and having read any number of times that the human brain is the most complex object known to exist in the universe, and that the mind is not identical with the brain but is more mysterious still, it seems to me this astonishing nexus of the self, so uniquely elegant and capable, merits a name that would indicate a difference in kind from the ontological run of things, and for my purposes "soul" would do nicely.
Perhaps I should pause here to clarify my meaning, since there are those who feel that the spiritual is diminished or denied when it is associated with the physical. I am not among them. In his Letter to the Romans, Paul says, "Ever since the creation of the world (God's) invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made." If we are to consider the heavens, how much more are we to consider the magnificent energies of consciousness that make whomever we pass on the street a far grander marvel than our galaxy?
At this point of dynamic convergence, call it self or call it soul, questions of right and wrong are weighed, love is felt, guilt and loss are suffered. And, over time, formation occurs, for weal or woe, governed in large part by that unaccountable capacity for self awareness.
The locus of the human mystery is perception of this world. From it proceeds every thought, every art. I like Calvin's metaphor--nature is a shining garment in which God is revealed and concealed. As we perceive we interpret, and we make hypotheses. Something is happening, it has a certain character or meaning which we usually feel we understand at least tentatively, though experience is almost always available to reinterpretations based on subsequent experience or reflection. Here occurs the weighing of moral and ethical choice. Behavior proceeds from all this, and is interesting, to my mind, in the degree that it can be understood to proceed from it.
