[T]he zealous never fail to draw political inferences from religious tenets, by which they interest the magistrate in the dispute; and then to the heat of a religious fervour is added the fury of a party zeal. All intercourse is cut off between the parties. They lose all knowledge of each other, tho' countrymen and neighbours, and are therefore easily imposed upon with the most absurd stories concerning each other's opinions and practices. They judge of the hatred of the adverse side by their own. Then fear is added to their hatred; and preventive injuries arise from their fear. The remembrance of the past, the dread of the future, the present ill, will join together to urge them forward to the most violent courses.
Such is the manner of proceeding of religious parties towards each other.

The remembrance of the past, the dread of the future, the present ill, will join together to urge them forward to the most violent courses.
