It seems to me that you are solving a problem which goes beyond the limits of physiology in too simple a way. Physiology has realized its problem with fortitude, breaking man down into endless actions and counteractions and reducing him to a crossing, a vortex of reflex acts.

Science even more than the Gospel teaches us humility. She cannot look down on anything, she does not know what superiority means, she despises nothing, never lies for the sake of a pose, and conceals nothing out of coquetry. She stops before the facts as an investigator, sometimes as a physician, never as an executioner, and still less with hostility and irony.
