Jealousy is a kind of civil war in the soul, where judgment and imagination are at perpetual jars

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 politic, commits great disorders, and lays all waste. Nothing stands safe in its way; Nature, interest, religion, must yield to its fury. It violates contracts, dissolves society, breaks wedlock, betrays friends and neighbours. No body is good, and every one is either doing or designing them a mischief. It has a venom that more or less rankles wherever it bites: And as it reports fancies or facts, so it disturbs its own house as often as other folks. — William Penn
