“In thinking lovingly about others, we think healthily about ourselves.”
– from Annals of a Quiet Neighborhood by George MacDonald
Yes- having to focus on the good of and for other people can take away some of the insanity that blinds us regarding our own situation. But if we are biased and really intent on gaining some good or ground for a personal cause, that can blind us to the good we ought to grant and teach to others. Take slavery for example.
