In short, the philosophers believe that religious laws are necessary political arts, the principles of which are taken from natural reason and inspiration, especially in what is common to all religions, although religions differ here more or less. The philosophers further hold that one must not object either through a positive or through a negative statement to any of the general religious principles, for instance whether it is obligatory to serve God or not, and still more whether God does or does not exist, and they affirm this also concerning the other religious principles, for instance bliss in the beyond and its possibility; for all religions agree in the acceptance of another existence after death, although they differ in the description of this existence, just as they agree about the knowledge, attributes, and acts of God, although they differ more or less in their utterances about the essence and the acts of the Principle. All religions agree also about the acts conducive to bliss in the next world, although they differ about the determination of these acts. Averroes
