"We should always act with great Cautiousness and Circumspection in Points, where it is not impossible that we may be deceived. Intemperate Zeal, Bigotry and Persecution for any Party or Opinion, how praiseworthy soever they may appear to weak Men of our own Principles, produce infinite Calamities among Mankind, and are highly Criminal in their own Nature; and yet how many Persons eminent for Piety suffer such monstrous and absurd Principles of Action to take Root in their Minds under the Colour of Virtues?"
— Addison, Joseph (1672-1719)
