Human reason reduced to its own resources is perfectly worthless, not only for creating but also for preserving any political or religious association, because it only produces disputes, and, to conduct himself well, man needs not problems but beliefs. His cradle should be surrounded by dogmas, and when his reason is awakened, it should find all his opinions ready-made, at least all those relating to his conduct. Nothing is so important to him as prejudices, Let us not take this word in a bad sense. It does not necessarily mean false ideas, but only, in the strict sense of the word, opinions adopted before any examination. Now these sorts of opinions are man’s greatest need, the true elements of his happiness, and the Palladium of empires. Without them, there can be neither worship, nor morality, nor government. There must be a state religion just as there is a state policy; or, rather, religious and political dogmas must be merged and mingled together to form a complete common or national reason strong enough to repress the aberrations of individual reason, which of its nature is the mortal enemy of any association whatever because it produces only divergent opinions. All known nations have been happy and powerful to the extent that they have more faithfully obeyed this national reason, which is nothing other than the annihilation of individual dogmas and the absolute and general reign of national dogmas, that is to say, of useful prejudices. Let each man call upon his individual reason in the matter of religion, and immediately you will see the birth of an anarchy of belief or the annihilation of religious sovereignty. Likewise, if each man makes himself judge of the principles of government, you will at once see the birth of civil anarchy or the annihilation of political sovereignty. Government is a true religion: it has its dogmas, its mysteries, and its ministers. To annihilate it or submit it to the discussion of each individual is the same thing; it lives only through national reason, that is to say through political faith, which is a creed. Man’s first need is that his nascent reason be curbed under this double yoke, that it be abased and lose itself in the national reason, so that it changes its individual existence into another common existence, just as a river that flows into the ocean always continues to exist in the mass of water, but without a name and without a distinct reality.
Even as to himself, a man cannot pretend to know what he is in himself from the knowledge he has by internal sensation. For as he does not as it were create himself, and does not come by the conception of himself a priori but empirically, it naturally follows that he can obtain his knowledge even of himself only by the inner sense, and consequently only through the appearances of his nature and the way in which his consciousness is affected. At the same time, beyond these characteristics of his own subject, made up of mere appearances, he must necessarily suppose something else as their basis, namely, his ego, whatever its characteristics in itself may be... Now man really finds in himself a faculty by which he distinguishes himself from everything else, even from himself as affected by objects, and that is reason. This being pure spontaneity is even elevated above the understanding. For although the latter is a spontaneity and does not, like sense, merely contain intuitions that arise when we are affected by things (and are therefore passive), yet it cannot produce from its activity any other conceptions than those which merely serve to bring the intuitions of sense under rules, and thereby to unite them in one consciousness, and without this use of the sensibility it could not think at all; whereas, on the contrary, reason shows so pure a spontaneity in the case of what I call "ideas" [Ideal Conceptions] that it thereby far transcends everything that the sensibility can give it, and exhibits its most important function in distinguishing the world of sense from that of understanding, and thereby prescribing the limits of the understanding itself.
