This negation discovers another immense error of the school and of its chief. Convinced, and with reason, that the observation of facts is the natural and constant process of the human understanding in its labor after knowledge, M. Auguste Comte has ill understood, and incompletely understood, the results of this labor. He failed to perceive that it was observation itself, carried on and accomplished by the process, no less natural and no less legitimate, of induction, which was revealing to the mind its peculiar facts and its peculiar laws, as well as the facts and the laws of the external world, within which that mind is placed. {297} M. Comte ended by ignoring or denying the elements _à priori_ of human knowledge; that is to say, the universal and necessary principles by which man raises himself to God, and has relations with God. Thus M. Comte mutilates the human mind, because he fails to observe it and to recognize it in its entirety. He is impelled by his system to another and still more serious mutilation of human nature. After having declared matter, its forces and its laws, to be the single object of human knowledge, and these laws to be inherent in matter, eternal and invariable, what is to be said of human liberty? What place is to be assigned to human liberty in this world, in which it is powerless to create anything or to change anything, and in which there exists no power from which it can demand anything or obtain anything? {298} Evidently, in such a system human liberty is a chimera, an idle luxury of human nature; man, with all his faculties, has nothing to do but to study matter carefully, its forces and its laws, to adapt himself to them, and to make the best use he can of them, with a view to his welfare and to the satisfaction of his desires. Fatalism is the law of man as of the world within which he lives!
