3863. As to what related to the progression of the general natural sense into the face - that it first occupied the whole face, afterwards the left part of the face, and at length the ear only - it is now given me to perceive that formerly when men were, as it were, in a state of integrity, then the natural operation, especially of the cerebellum, was immediately shown in the whole face, as much the changes of their affections or celestial principles, which pertain to the right side of the face, as of their spiritual workings, which belong to the left side of the face. When the affections of good ceased, and were succeeded by vile cupidities only, then the natural operation into the right part of the face receded, and betook itself to the left, into which it, acted from spiritual principles, thus in inverted order, that is, not from celestial promptings to spiritual, or from the right to the left, but from spirituals to celestials, thus from the left; but it is not lawful to proceed from left to right, or from spirituals to celestials, wherefore the right side of the face is guarded by the Lord, that [the influx] may not extend itself thither from the left, which appears from faith, that faith is without the affection of good, to which faith it is not granted to enter into the affections of good, thus into celestial things, on which account it is separated, and at this day faith is scientific, or of the memory, by which men wish to enter heaven, although destitute of any affection of good, or love; for they suppose that provided they have faith they will be saved, when [at the same time] their life may be contrary and [made up] of mere cupidities.
