Famous quotes containing the word difference:

    “One lesson we learn early, that in spite of seeming difference, men are all of one pattern. We readily assume this with our mates, and are disappointed and angry if we find that we are premature, and that their watches are slower than ours. In fact, the only sin which we never forgive in each other is difference of opinion.”
    —Ralph Waldo Emerson (1803–1882)
