I admit all distinctions, all inequalities, all sincerity. I only affirm two things; one, that all the philosophic schools of our day, different as may be their systems and merits, have this in common, that they deny this supernatural order, and strive to explain and govern man and the world without its aid; the other, that where faith in this order does not exist, the bases of moral and social order are deeply and increasingly shaken, man having ceased to live in presence of the only power which really surpasses him, and which is able at once to satisfy and direct him. Natural order is the field open to man's knowledge. Supernatural order is so in degree to his faith and hope; but knowledge does not penetrate it. In the order of nature man exercises a share of action and power; in supernatural order he has but to submit. It has been said in the spirit of conciliation and peace, "Religion and Philosophy are sisters who should mutually respect and protect each other." {12} The words bear the stamp of the chimæras of human pride. Philosophy springs from man; it is the work of his mind. Religion comes from God; man receives it, and often alters it after reception, but he does not create it. Religion and philosophy are not sisters. They are daughters, the one of "Our Father which is in Heaven," the other of mere human genius. And their condition in this world is no more equal than their origin. Authority is the apanage of religion; liberty is that of philosophy. I now approach the second of the dominant ideas, more than ever essential to true order, and which I wish to bring prominently forward. "Christianity," says M. Veuillot, "is authority." It is true; Christianity is authority, but it is not authority only; it is the entire man, all his nature and all his destiny. Now, moral obedience is the nature and destiny of man; that is, obedience in a state of liberty. God created man to obey His laws; he created him free that he might morally obey. Liberty, like authority, is of divine institution; the work of man is revolt and tyranny. In the social state, authority and liberty need protection, and both have a right to it. There is need of control, both for the governors and the governed, for both are men. Hence political laws and institutions which now sustain, now limit power; that is, which decide on what conditions and by what means authority is to be exercised and liberty secured. {13} What is the measure of authority necessary for Government, what the extent of liberty possible in human society? What are the means of action, what the pledges to be given alike to authority and religion? Matters depending on circumstances, variable according to the times, the social condition, the manners, races, and different degrees of civilization amongst nations. It belongs to the politician to solve these questions.
