I am far from contesting this principle with them, but they forget that it _has_ been, and still _is_, strongly contested: contested by both ancient and modern philosophers. Some have considered the pursuit of happiness, and the satisfaction of individual interests, as the right and legitimate aims of human life. Others have placed the rule of man's conduct, not in personal interests, but in general utility, in the common welfare of all mankind. Others have thought that they could perceive the origin and the guarantee for morals in the sympathy of human sentiments. {56} The moral and obligatory law, or duty, is far from being the recognised and generally accepted basis of morality; systems the most varied have arisen, and are incessantly forming themselves, with respect to the principles of morals, as with respect to other great questions of our nature; and the human understanding fluctuates no less in this corner of the philosophic arena than in the others. Let the moralists of the new school not deceive themselves; in proclaiming morality to be independent of religion, they mean to give it one fixed basis, the same for all, and they believe that they succeed in the attempt. They deceive themselves: morality, thus isolated, remains as much as ever a prey to the disputes of man. I pass over this grave misconception on the part of the defenders of the system, and I examine the system itself. Let us see if it is the faithful and full expression of human morality, if it contains all the facts which constitute its natural and essential elements. {57} These facts I sum up as follows: the distinction between moral good and evil; the obligation of doing good and avoiding evil; the faculty of accomplishing or not this obligation. In brief and philosophic terms the Moral Law, Duty, and Liberty. These are the natural, primitive, and universal facts which constitute human morality; it is by reason and by virtue of these facts that man is a moral being. I have not here to enter into a discussion of these same facts; I do not occupy myself at this moment with systems which disregard or deny them, in whole or in part; all the three facts, or any one of the three. The partisans of the system of independent morality admit them all, as I do; the question between them and myself is this, whether or not, whilst rendering homage to the true principle of morality, they fully comprehend its signification, and accept its results. {58} It is the characteristic and the honour of man that he is not satisfied with merely gathering facts which relate either to himself or to the external world, but that he seeks to know their origin and object, their import and bearing.
