It is an error to suppose that no man understands his own character. Most persons know even their failings very well, only they persist in giving them names different from those usually assigned by the rest of the world; and they compensate for this mistake by naming, at first sight, with singular accuracy, those very same failings in others.

Arthur Helps (1813-1875) English writer and bureaucrat
