“We have flattered ourselves by inventing proverbs of comparison in matter of blindness,--"blind as a bat," for instance. It would be safe to say that there cannot be found in the animal kingdom a bat, or any other creature, so blind in its own range of circumstance and connection, as the greater majority of human beings are in the bosoms of their families. Tempers strain and recover, hearts break and heal, strength falters, fails, and comes near to giving way altogether, every day, without being noted by the closest lookers-on.”

“When it comes to ourselves, we often have a blind spot. That is, we fail to see ourselves as others see us. We fail to recognize our most obvious traits: our strengths, weaknesses, mannerisms.”

“Luck is stupid as a cow and blind as a bat.”

“People give themselves to you, in their talking, and in other ways, if you are quiet and patient and let them, and not in such a damned rush to give yourself to them you go bat-blind and deaf.”

“In their behavior toward creatures, all men are Nazis. Human beings see oppression vividly when they're the victims. Otherwise they victimize blindly and without a thought.”

“Judging others makes us blind, whereas love is illuminating. By judging others we blind ourselves to our own evil and to the grace which others are just as entitled to as we are.”
