Umberto Eco said this quote
“ The excluded when on living on the fringe, like lepers, of whom true leper are only the illustration ordained by god to make us understand this wondrous parable, so that in saying “lepers” we would understand “outcast, poor, simple, excluded, uprooted from the countryside, humiliated in the cities” but we did not understand; the mystery of leprosy has continued to haunt us because we have not recognized the nature of the sign. Excluded as they were from the flock, all of them were ready to hear, or to produce, every sermon that, harking back to the words of Christ, would condemn the behaviour of the dogs and shepherds and would promise their punishment one day. The powerful have always realised this. The recovery of the outcasts demanded a reduction of the privileges of the powerful, so the excluded who became aware of their exclusion had to be branded as heretics, whatever their doctrine. This is the illusion of heresy. Everyone is heretical, everyone is orthodox. The faith a movement proclaims doesn’t count: what counts is the hope it offers. ”
