At the time and in the country in which the present study was written, it was granted by everyone except backward people that the Jewish faith had not been refuted by science or by history.... one could grant to science and history everything they seem to teach regarding the age of the world, the origin of man, the impossibility of miracles, the impossibility of the immortality of the soul, and of the resurrection of the body, the Jahvist, the Elohist, the third Isaah, and so on, without abandoning one iota of the substance of the Jewish faith.
