The ear tends to be lazy, craves the familiar and is shocked by the unexpected; the eye, on the other hand, tends to be impatient, craves the novel and is bored by repetition.
W. H. AudenWe are not commanded (or forbidden) to love our mates, our children, our friends, our country because such affections come naturally to us and are good in themselves, although we may corrupt them. We are commanded to love our neighbor because our natural attitude toward the other is one of either indifference or hostility.
W. H. Auden
