No publisher should ever express an opinion on the value of what he publishes.
That is a matter entirely for the literary critic to decide. I can quite understand how any ordinary critic would be strongly prejudiced against a work that was accompanied by a premature and unnecessary panegyric from the publisher. A publisher is simply a useful middle-man. It is not for him to anticipate the verdict of criticism.
The highest panegyric, therefore, that private virtue can receive, is the praise of servants.
So near are the boundaries of panegyric and invective, that a worn-out sinner is sometimes found to make the best declaimer against sin. The same high-seasoned descriptions which in his unregenerate state served to inflame his appetites, in his new province of a moralist will serve him (a little turned) to expose the enormity of those appetites in other men.
Every other enjoyment malice may destroy;
every other panegyric envy may withhold; but no human power can deprive the boaster of his own encomiums.
