If so, we have before us an expiation too seldom noticed but altogether just. All crime must be expiated, and slavery is the repetition among men of the sufferings brutally imposed by man upon other living beings; it is the theory bearing its fruits. The right of man over the animal seems to me to cease with the need of defense and of subsistence. So that all unnecessary murder and torture are cowardice and even crime. The animal renders a service of utility; man in return owes it a need of protection and of kindness. In a word, the animal has claims on man, and the man has duties to the animal. Buddhism, no doubt, exaggerates this truth, but the Westerns leave it out of count altogether. A day will come, however, when our standard will be higher, our humanity more exacting, than it is to-day. _Homo homini lupus_, said Hobbes: the time will come when man will be humane even for the wolf--_homo lupo homo_. December 30, 1866.--Skepticism pure and simple as the only safeguard of intellectual independence--such is the point of view of almost all our young men of talent. Absolute freedom from credulity seems to them the glory of man. My impression has always been that this excessive detachment of the individual from all received prejudices and opinions in reality does the work of tyranny. This evening, in listening to the conversation of some of our most cultivated men, I thought of the Renaissance, of the Ptolemies, of the reign of Louis XV., of all those times in which the exultant anarchy of the intellect has had despotic government for its correlative, and, on the other hand, of England, of Holland, of the United States, countries in which political liberty is bought at the price of necessary prejudices and _à priori_ opinions. That society may hold together at all, we must have a principle of cohesion--that is to say, a common belief, principles recognized and undisputed, a series of practical axioms and institutions which are not at the mercy of every caprice of public opinion. By treating everything as if it were an open question, we endanger everything. Doubt is the accomplice of tyranny. “If a people will not believe it must obey,” said Tocqueville. All liberty implies dependence, and has its conditions; this is what negative and quarrelsome minds are apt to forget. They think they can do away with religion; they do not know that religion is indestructible, and that the question is simply, Which will you have? Voltaire plays the game of Loyola, and _vice versâ_. Between these two there is no peace, nor can there be any for the society which has once thrown itself into the dilemma. The only solution lies in a free religion, a religion of free choice and free adhesion.
