Erewhon by Samuel Butler

Let me leave this unhappy story, and return to the course of events among the Erewhonians at large. No matter how many laws they passed increasing the severity of the punishments inflicted on those who ate meat in secret, the people found means of setting them aside as fast as they were made. At times, indeed, they would become almost obsolete, but when they were on the point of being repealed, some national disaster or the preaching of some fanatic would reawaken the conscience of the nation, and people were imprisoned by the thousand for illicitly selling and buying animal food.

About six or seven hundred years, however, after the death of the old prophet, a philosopher appeared, who, though he did not claim to have any communication with an unseen power, laid down the law with as much confidence as if such a power had inspired him. Many think that this philosopher did not believe his own teaching, and, being in secret a great meat-eater, had no other end in view than reducing the prohibition against eating animal food to an absurdity, greater even than an Erewhonian Puritan would be able to stand.
