Now I assert that all arguments without exception that tend towards theoretical conviction, are powerless to produce any assurance of the above type, from its highest degree to its lowest, where the proposition that is to be proved is the existence of an original being, regarded as a God in the sense appropriate to the complete content of this concept, that is to say, regarded as a moral author of the world, and, consequently, in such a way that the final end of creation is at once derived from him.
