Judaism, Christianity and Islam are not just three different religions or civilisations. Had this been so, the devotees of each might still consider themselves a chosen people. More generously, each might have come to Niels Bohr's conclusion that the opposite of a trivial truth is a falsehood, but the opposite of a profound truth may be another profound truth. There is more than one way of being-in-the-world under the sovereignty of God. More probably they would simply have ignored one another. Their differences would not have led to centuries of bloodshed and animosity.
