In further foreshadowings of Catharism, the Essenes’ worldview was essentially dualist, in that they saw the world as the battleground between the forces of heaven and hell, and that man himself is the microcosm of this war: ‘the spirits of truth and falsehood struggle within the human heart. …According to his share in truth and right, thus a man hates lies; and according to his share in the lot of deceit, thus he hates the truth.’
