The religious observances of his home and of the synagogue aroused in the boy a feeling of aversion as dead ritual; the religious instruction he received at home made as little impression on him as his attendance at the synagogue. Certain prayers, as, for instance, the prayer for the reinstitution of sacrificial worship, displeased him, in spite of his boyish orthodoxy. To the horror of those about him, he said: "That is a stupid prayer." His learning was mere committing to memory, his teacher not believing himself what he taught; and it was all quickly forgotten. As a grown man, he did not know a single word of Hebrew, had no understanding whatever of Jewish customs, and no affection even for the Old Testament, of which Heine was such an enthusiastic admirer. The man who himself reminds us of an Old Testament prophet, has not one allusion to the prophets in all his writings. From time to time, indeed, with complete indifference, and merely as a well-known illustration, he refers to some Bible narratives; but as Steinthal acutely observes, he quotes even such a passage as Samuel's republican warning against the establishment of a kingdom, which one would expect to excite his every sympathy, as if he were quoting one of Æsop's fables.[3] Schiller's essay, _The Mission of Moses_, was the first hint of a rational conception of religion that reached the boy. It made a deep impression on him, and shook his faith. Naïvely simple as the essay is, with its implicit trust in the historic accuracy of the Bible narrative, it yet inevitably produced a revolution in the mind of the youthful reader, who now for the first time saw the most important events in the life of his people and of their lawgiver divested of every miraculous element, Providence itself being superseded by "destiny." Various anecdotes exist, illustrating the awakening of the spirit of criticism in the boy, and the play of the different forces which formed his character. One day, when it was raining heavily and the road was inch-deep in mud, he was walking with his tutor outside the gates of the town. "Let us walk on the footpath," said Börne. "Do you not know," answered the teacher, "that we are forbidden to do that?" The boy's reply, "no one sees us," gave the tutor an opportunity for a moral exhortation, with remarks on the sacredness of law. "That is a stupid law," said Börne.
