It would not be possible, in the course of a short introduction, to deal both with the positive content of Rousseau’s thought and with the actual influence he has had on practical affairs. The statesmen of the French Revolution, from Robespierre downwards, were throughout profoundly affected by the study of his works. Though they seem often to have misunderstood him, they had on the whole studied him with the attention he demands. In the nineteenth century, men continued to appeal to Rousseau, without, as a rule, knowing him well or penetrating deeply into his meaning. “The Social Contract,” says M. Dreyfus-Brisac, “is the book of all books that is most talked of and least read.” But with the great revival of interest in political philosophy there has come a desire for the better understanding of Rousseau’s work. He is again being studied more as a thinker and less as an ally or an opponent; there is more eagerness to sift the true from the false, and to seek in the Social Contract the “principles of political right,” rather than the great revolutionary’s ipse dixit in favour of some view about circumstances which he could never have contemplated.
The Social Contract, then, may be regarded either as a document of the French Revolution, or as one of the greatest books dealing with political philosophy. It is in the second capacity, as a work of permanent value containing truth, that it finds a place among the world’s great books. It is in that capacity also that it will be treated in this introduction. Taking it in this aspect, we have no less need of historical insight than if we came to it as historians pure and simple. To understand its value we must grasp its limitations; when the questions it answers seem unnaturally put, we must not conclude that they are meaningless; we must see if the answer still holds when the question is put in a more up-to-date form.
First, then, we must always remember that Rousseau is writing in the eighteenth century, and for the most part in France. Neither the French monarchy nor the Genevese aristocracy loved outspoken criticism, and Rousseau had always to be very careful what he said. This may seem a curious statement to make about a man who suffered continual persecution on account of his subversive doctrines; but, although Rousseau was one of the most daring writers of his time, he was forced continually to moderate his language and, as a rule, to confine himself to generalisation instead of attacking particular abuses. Rousseau’s theory has often been decried as too abstract and metaphysical. This is in many ways its great strength; but where it is excessively so, the accident of time is to blame. In the eighteenth century it was, broadly speaking, safe to generalise and unsafe to particularise. Scepticism and discontent were the prevailing temper of the intellectual classes, and a shortsighted despotism held that, as long as they were confined to these, they would do little harm. Subversive doctrines were only regarded as dangerous when they were so put as to appeal to the masses; philosophy was regarded as impotent. The intellectuals of the eighteenth century therefore generalised to their hearts’ content, and as a rule suffered little for their lèse-majesté: Voltaire is the typical example of such generalisation. The spirit of the age favoured such methods, and it was therefore natural for Rousseau to pursue them. But his general remarks had such a way of bearing very obvious particular applications, and were so obviously inspired by a particular attitude towards the government of his day, that even philosophy became in his hands unsafe, and he was attacked for what men read between the lines of his works. It is owing to this faculty of giving his generalisations content and actuality that Rousseau has become the father of modern political philosophy. He uses the method of his time only to transcend it; out of the abstract and general he creates the concrete and universal.
Secondly, we must not forget that Rousseau’s theories are to be studied in a wider historical environment. If he is the first of modern political theorists, he is also the last of a long line of Renaissance theorists, who in turn inherit and transform the concepts of medieval thought. So many critics have spent so much wasted time in proving that Rousseau was not original only because they began by identifying originality with isolation: they studied first the Social Contract by itself, out of relation to earlier works, and then, having discovered that these earlier works resembled it, decided that everything it had to say was borrowed. Had they begun their study in a truly historical spirit, they would have seen that Rousseau’s importance lies just in the new use he makes of old ideas, in the transition he makes from old to new in the general conception of politics. No mere innovator could have exercised such an influence or hit on so much truth. Theory makes no great leaps; it proceeds to new concepts by the adjustment and renovation of old ones. Just as theological writers on politics, from Hooker to Bossuet, make use of Biblical terminology and ideas; just as more modern writers, from Hegel to Herbert Spencer, make use of the concept of evolution, Rousseau uses the ideas and terms of the Social Contract theory. We should feel, throughout his work, his struggle to free himself from what is lifeless and outworn in that theory, while he develops out of it fruitful conceptions that go beyond its scope. A too rigid literalism in the interpretation of Rousseau’s thought may easily reduce it to the possession of a merely “historical interest”: if we approach it in a truly historical spirit, we shall be able to appreciate at once its temporary and
