It was partly the hope of earning money that led him to seek a publisher for 'The Robbers'. Friend Petersen was exhorted to find one, if possible, and was promised whatever he could get for the piece over and above fifty florins. But Petersen had no luck and at last the ambitious author decided, as the author of 'Götz' had done before him, to print his drama at his own expense. The money that he borrowed for the purpose, on the security of a friend, involved him in debts that were to hang over him for years and cause him endless trouble.
His plan once formed he began to take counsel with friends and revise his manuscript in the light of their criticisms. Even after the printing had begun, the revision continued. Things looked differently in the cold type of the proof-sheet, and he saw that he had occasionally gone too far in the direction of coarseness and extravagance. Thus the original draft had provided that Amalia should actually be sent to a convent, and that the furious Karl should appear with his robbers and threaten to convert the nunnery into a brothel unless his sweetheart should be delivered to him. This scene was condemned and the exploit given a more appropriate place among the _res gestae_ of Spiegelberg. In many places extravagant diction was toned down. The original preface, which was mainly occupied with a labored defence of the literary drama as against the stage-play, was rejected, and a new preface written which was devoted chiefly to moral considerations. The author here admitted that he had portrayed characters who would offend the virtuous, but insisted that he could not do otherwise if he was to copy nature, because in the real world virtue shines only in contrast with vice. He went on to say:
He who makes it his object to overthrow vice, and to avenge religion, morality and social law upon their enemies, must unveil vice in all its naked hideousness and bring it before the eyes of mankind in colossal size; he must himself wander temporarily through its nocturnal labyrinths and must be able to force himself into states of feeling that revolt his soul by their unnaturalness. I may properly claim for my work, in view of its remarkable catastrophe, a place among moral books. Vice meets the end that befits it. The wanderer returns to the track of law. Virtue triumphs. Whoever is fair enough to read me through and try to understand me, from him I may expect, not that he admire the poet, but that he respect the right-minded man.
