“for as we are never in a proper condition of doing justice to others, while we continue under the influence of some leading partiality, so neither are we capable of doing it to ourselves while we remain fettered by any obstinate prejudice. And as a man, who is attached to a prostitute, is unfitted to choose or judge a wife, so any prepossession in favour of a rotten constitution of government will disable us from discerning a good one.”
