If I bow before the authority of the specialists and avow my readiness to follow, to a certain extent and as long as may seem to me necessary, their indications and even their directions, it is because their authority is imposed upon me by no one, neither by men nor by God. Otherwise I would repel them with horror, and bid the devil take their counsels, their directions, and their services, certain that they would make me pay, by the loss of my liberty and self-respect, for such scraps of truth, wrapped in a multitude of lies, as they might give me. I bow before the authority of special men because it is imposed upon me by my own reason. I am conscious of my inability to grasp, in all its details and positive developments, any very large portion of human knowledge. The greatest intelligence would not be equal to a comprehension of the whole. Thence results, for science as well as for industry, the necessity of the division and association of labor. I receive and I give--such is human life. Each directs and is directed in his turn. Therefore there is no fixed and constant authority, but a continual exchange of mutual, temporary, and, above all, voluntary authority and subordination. This same reason forbids me, then, to recognize a fixed, constant, and universal authority, because there is no universal man, no man capable of grasping in that wealth of detail, without which the application of science to life is impossible, all the sciences, all the branches of social life. And if such universality could ever be realized in a single man, and if he wished to take advantage thereof to impose his authority upon us, it would be necessary to drive this man out of society, because his authority would inevitably reduce all the others to slavery and imbecility. I do not think that society ought to maltreat men of genius as it has done hitherto; but neither do I think it should indulge them too far, still less accord them any privileges or exclusive rights whatsoever; and that for three reasons: first, because it would often mistake a charlatan for a man of genius; second, because, through such a system of privileges, it might transform into a charlatan even a real man of genius, demoralize him, and degrade him; and, finally, because it would establish a master over itself. To sum up. We recognize, then, the absolute authority of science, because the sole object of science is the mental reproduction, as well-considered and systematic as possible, of the natural laws inherent in the material, intellectual, and moral life of both the physical and the social worlds, these two worlds constituting, in fact, but one and the same natural world. Outside of this only legitimate authority, legitimate because rational and in harmony with human liberty, we declare all other authorities false, arbitrary and fatal.
