How prone we are to come to the consideration of every question with heads and hearts pre-occupied! How prone to shrink from any opinion, however reasonable, if it be opposed to any, however unreasonable, of our own! How disposed are we to judge, in anger, those who call upon us to think, and encourage us to enquire! To question our prejudices seems nothing less than sacrilege; to break the chains of our ignorance, nothing short of impiety!
