mirror of the mind

If the face is the mirror of the mind, as Saint Jerome observed, then what happens when the face is disfigured by the savagery of war?

But what if you could create neural interfaces that would act as a mirror of the mind?

Sincerity is the true and perfect mirror of the mind.

O softly, O tenderly, the heart now stirs     With desires faint and formless; and, seeking not, I find Quiet thoughts that flash like azure kingfishers     Across the luminous, tranquil mirror of the mind.

The body's shapely mould Attests the Maker's art, that in the face, The mirror of the mind, doth best appear.
