It was remarked by a man of genius that “ignorance lies at the two ends of knowledge.” Perhaps it would have been more correct to have said, that absolute convictions are to be met with at the two extremities, and that doubt lies in the middle; for the human intellect may be considered in three distinct states, which frequently succeed one another. A man believes implicitly, because he adopts a proposition without inquiry. He doubts as soon as he is assailed by the objections which his inquiries may have aroused. But he frequently succeeds in satisfying these doubts, and then he begins to believe afresh: he no longer lays hold on a truth in its most shadowy and uncertain form, but he sees it clearly before him, and he advances onwards by the light it gives him. *c c [ It may, however, be doubted whether this rational and self-guiding conviction arouses as much fervor or enthusiastic devotedness in men as their first dogmatical belief.] When the liberty of the press acts upon men who are in the first of these three states, it does not immediately disturb their habit of believing implicitly without investigation, but it constantly modifies the objects of their intuitive convictions. The human mind continues to discern but one point upon the whole intellectual horizon, and that point is in continual motion. Such are the symptoms of sudden revolutions, and of the misfortunes which are sure to befall those generations which abruptly adopt the unconditional freedom of the press. The circle of novel ideas is, however, soon terminated; the touch of experience is upon them, and the doubt and mistrust which their uncertainty produces become universal. We may rest assured that the majority of mankind will either believe they know not wherefore, or will not know what to believe. Few are the beings who can ever hope to attain to that state of rational and independent conviction which true knowledge can beget in defiance of the attacks of doubt. It has been remarked that in times of great religious fervor men sometimes change their religious opinions; whereas in times of general scepticism everyone clings to his own persuasion. The same thing takes place in politics under the liberty of the press. In countries where all the theories of social science have been contested in their turn, the citizens who have adopted one of them stick to it, not so much because they are assured of its excellence, as because they are not convinced of the superiority of any other. In the present age men are not very ready to die in defence of their opinions, but they are rarely inclined to change them; and there are fewer martyrs as well as fewer apostates. Another still more valid reason may yet be adduced: when no abstract opinions are looked upon as certain, men cling to the mere propensities and external interests of their position, which are naturally more tangible and more permanent than any opinions in the world.
