Open passage
Voluntary Blindness.—There is a kind of enthusiastic and extreme devotion to a person or a party which reveals that in our inmost hearts we feel ourselves superior to this person or party, and for this reason we feel indignant with ourselves. We blind ourselves, as it were, of our own free will to punish our eyes for having seen too much.
