April 5, 1864.--I have been reading “Prince Vitale” for the second time, and have been lost in admiration of it. What wealth of color, facts, ideas--what learning, what fine-edged satire, what _esprit_, science, and talent, and what an irreproachable finish of style--so limpid, and yet so profound! It is not heartfelt and it is not spontaneous, but all other kinds of merit, culture, and cleverness the author possesses. It would be impossible to be more penetrating, more subtle, and less fettered in mind, than this wizard of language, with his irony and his chameleon-like variety. Victor Cherbuliez, like the sphinx, is able to play all lyres, and takes his profit from them all, with a Goethe-like serenity. It seems as if passion, grief, and error had no hold on this impassive soul. The key of his thought is to be looked for in Hegel’s “Phenomenology of Mind,” remolded by Greek and French influences. His faith, if he has one, is that of Strauss-Humanism. But he is perfectly master of himself and of his utterances, and will take good care never to preach anything prematurely. What is there quite at the bottom of this deep spring? In any case a mind as free as any can possibly be from stupidity and prejudice. One might almost say that Cherbuliez knows all that he wishes to know, without the trouble of learning it. He is a calm Mephistopheles, with perfect manners, grace, variety, and an exquisite urbanity; and Mephisto is a clever jeweler; and this jeweler is a subtle musician; and this fine singer and storyteller, with his amber-like delicacy and brilliancy, is making mock of us all the while. He takes a malicious pleasure in withdrawing his own personality from scrutiny and divination, while he himself divines everything, and he likes to make us feel that although he holds in his hand the secret of the universe, he will only unfold his prize at his own time, and if it pleases him. Victor Cherbuliez is a little like Proudhon and plays with paradoxes, to shock the _bourgeois_. Thus he amuses himself with running down Luther and the Reformation in favor of the Renaissance. Of the troubles of conscience he seems to know nothing. His supreme tribunal is reason. At bottom he is Hegelian and intellectualist. But it is a splendid organization. Only sometimes he must be antipathetic to those men of duty who make renunciation, sacrifice, and humility the measure of individual worth.
