It also appears to me that when prejudices persist obstinately, it is the fault of nobody so much as of those who make a point of proclaiming them insuperable, as an excuse to themselves for never joining in an attempt to remove them. Any prejudice whatever will be insurmountable if those who do not share it themselves truckle to it, and flatter it, and accept it as a law of nature.
