In general falsities have two sources. The first group derive from the desires that belong to self-love and love of the world, the second from cognitions and facts by way of reasonings. Falsities derived in this way, when they wish to have dominion over truths, are meant by 'Sodom, Gomorrah, Admah, and Zeboiim'. 'Gomorrah' signifies the falsity derived from self-love.
