I argued as follows, telling myself that the knowledge of faith flows, like all humanity with its reason, from a mysterious source. That source is God, the origin both of the human body and the human reason. As my body has descended to me from God, so also has my reason and my understanding of life, and consequently the various stages of the development of that understanding of life cannot be false. All that people sincerely believe in must be true; it may be differently expressed but it cannot be a lie, and therefore if it presents itself to me as a lie, that only means that I have not understood it. Furthermore I said to myself, the essence of every faith consists in its giving life a meaning which death does not destroy.
