  • "Jealousy is a kind of Civil War in the Soul, where Judgment and Imagination are at perpetual Jars.

    This Civil Dissension in the Mind, like that of the Body Politick, commits great Disorders, and lays all waste.

    Nothing stands safe in its Way: Nature, Interest, Religion, must Yield to its Fury."

    - William Penn, 'Fruits of Solitude'.
