"Heresy originates a new life of its own"
"THE denial of a scheme wholesale is not heresy, and has not the creative power of a heresy. It is of the essence of heresy that it leaves standing a great part of the structure it attacks. On this account it can appeal to believers and continues to affect their lives through deflecting them from their original characters. Wherefore, it is said of heresies that "they survive by the truths they retain."
"We must note that whether the complete scheme thus attacked be true or false is indifferent to the value of heresy as a department of historical study. What we are concerned with is the highly interesting truth that heresy originates a new life of its own and vitally affects the society it attacks."
~Hilaire Belloc: The Great Heresies.
