If French booksellers in the stirring intellectual time of the eighteenth century needed all the craft of a smuggler, their morality was reduced to an equally low level in dealing not only with the police, but with their own accomplices, the book-writers. They excused themselves from paying proper sums to authors, on the ground that they were robbed of the profits that would enable them to pay such sums, by the piracy of their brethren in trade. But then they all pirated the works of one another. The whole commerce was a mass of fraud and chicane, and every prominent author passed his life between two fires. He was robbed, his works were pirated, and, worse than robbery and piracy, they were defaced and distorted by the booksellers. On the other side he was tormented to death by the suspicion and timidity, alternately with the hatred and active tyranny of the administration. As we read the story of the lives of all these strenuous men, their struggles, their incessant mortifications, their constantly reviving and ever irrepressible vigour and interest in the fight, we may wish that the shabbiness and the pettiness of the daily lives of some of them had faded away from memory, and left us nothing to think of in connection with their names but the alertness, courage, tenacity, self-sacrifice, and faith with which they defended the cause of human emancipation and progress. Happily the mutual hate of the Christian factions, to which liberty owes at least as much as charity owes to their mutual love, prevented a common union for burning the philosophers as well as their books. All torments short of this they endured, and they had the great merit of enduring them without any hope of being rewarded after their death, as truly good men must always be capable of doing.
