“The soul is imprisoned in the body, and the Lord… built two windows in the wall of the prison… Unfortunately, the windows have curtains—eyelids; and a man whose soul is impure, feeling himself scrutinized, lets down the curtains and conceals the soul.”

Address at Illinois College (1881)
Context: Character is the entity, the individuality of the person, shining from every window of the soul, either as a beam of purity, or as a clouded ray that betrays the impurity within. The contest between light and darkness, right and wrong, goes on; day by day, hour by hour, moment by moment, our characters are being formed, and this is the all-important question which comes to us in accents ever growing fainter as we journey from the cradle to the grave, "Shall those characters be good or bad?"
