At the same time, while observation becomes more difficult, it is more carelessly and badly done; this is another reason for the small success of our researches into the natural history of the human race. The information acquired by travel depends upon the object of the journey. If this object is a system of philosophy, the traveller only sees what he desires to see; if it is self-interest, it engrosses the whole attention of those concerned. Commerce and the arts which blend and mingle the nations at the same time prevent them from studying each other. If they know how to make a profit out of their neighbours, what more do they need to know?
It is a good thing to know all the places where we might live, so as to choose those where we can live most comfortably. If every one lived by his own efforts, all he would need to know would be how much land would keep him in food. The savage, who has need of no one, and envies no one, neither knows nor seeks to know any other country but his own. If he requires more land for his subsistence he shuns inhabited places; he makes war upon the wild beasts and feeds on them. But for us, to whom civilised life has become a necessity, for us who must needs devour our fellow-creatures, self-interest prompts each one of us to frequent those districts where there are most people to be devoured. This is why we all flock to Rome, Paris, and London. Human flesh and blood are always cheapest in the capital cities. Thus we only know the great nations, which are just like one another.
They say that men of learning travel to obtain information; not so, they travel like other people from interested motives. Philosophers like Plato and Pythagoras are no longer to be found, or if they are, it must be in far-off lands. Our men of learning only travel at the king’s command; they are sent out, their expenses are paid, they receive a salary for seeing such and such things, and the object of that journey is certainly not the study of any question of morals. Their whole time is required for the object of their journey, and they are too honest not to earn their pay. If in any country whatsoever there are people travelling at their own expense, you may be sure it is not to study men but to teach them. It is not knowledge they desire but ostentation. How should their travels teach them to shake off the yoke of prejudice? It is prejudice that sends them on their travels.
To travel to see foreign lands or to see foreign nations are two very different things. The former is the usual aim of the curious, the latter is merely subordinate to it. If you wish to travel as a philosopher you should reverse this order. The child observes things till he is old enough to study men. Man should begin by studying his fellows; he can study things later if time permits.
It is therefore illogical to conclude that travel is useless because we travel ill. But granting the usefulness of travel, does it follow that it is good for all of us? Far from it; there are very few people who are really fit to travel; it is only good for those who are strong enough in themselves to listen to the voice of error without being deceived, strong enough to see the example of vice without being led away by it. Travelling accelerates the progress of nature, and completes the man for good or evil. When a man returns from travelling about the world, he is what he will be all his life; there are more who return bad than good, because there are more who start with an inclination towards evil. In the course of their travels, young people, ill-educated and ill-behaved, pick up all the vices of the nations among whom they have sojourned, and none of the virtues with which those vices are associated; but those who, happily for themselves, are well-born, those whose good disposition has been well cultivated, those who travel with a real desire to learn, all such return better and wiser than they went. Emile will travel in this fashion; in this fashion there travelled another young man, worthy of a nobler age; one whose worth was the admiration of Europe, one who died for his country in the flower of his manhood; he deserved to live, and his tomb, ennobled by his virtues only, received no honour till a stranger’s hand adorned it with flowers.
Everything that is done in reason should have its rules. Travel, undertaken as a part of education, should therefore have its rules. To travel for travelling’s sake is to wander, to be a vagabond; to travel to learn is still too vague; learning without some definite aim is worthless. I would give a young man a personal interest in learning, and that interest, well-chosen, will also decide the nature of the instruction. This is merely the continuation of the method I have hitherto practised.
Now after he has considered himself in his physical relations to other creatures, in his moral relations with other men, there remains to be considered his civil relations with his fellow-citizens. To do this he must first study the nature of government in general, then the different forms of government, and lastly the particular government under which he was born, to know if it suits him to live under it; for by a right which nothing can abrogate, every man, when he comes of age, becomes his own master, free to renounce the contract by which he forms part of the community, by leaving the country in which that contract holds good. It is only by sojourning in that country, after he has come to years of discretion, that he is supposed to have tacitly confirmed the pledge given by his ancestors. He acquires the right to renounce his country, just as he has the right to renounce all claim to his father’s lands; yet his place of birth was a gift of nature, and in renouncing it, he renounces what is his own. Strictly speaking, every man remains in the land of his birth at his own risk unless he voluntarily submits to its laws in order to acquire a right to their protection.
For example, I should say to Emile, “Hitherto you have lived under my guidance, you were unable to rule yourself. But now you are approaching the age when the law, giving you the control over your property, makes you master of your person. You are about to find yourself alone in society, dependent on everything, even on your patrimony. You mean to marry; that is a praiseworthy intention, it is one of the duties of man; but before you marry you must know what sort of man you want to be, how you wish to spend your life, what steps you mean to take to secure a living for your family and for yourself; for although we should not make this our main business, it must be definitely considered. Do you wish to be dependent on men whom you despise? Do you wish to establish your fortune and determine your position by means of civil relations which will make you always dependent on the choice of others, which will compel you, if you would escape from knaves, to become a knave yourself?”
In the next place I would show him every possible way of using his money in trade, in the civil service, in finance, and I shall show him that in every one of these there are risks to be taken, every one of them places him in a precarious and dependent position, and compels him to adapt his morals, his sentiments, his conduct to the example and the prejudices of others.
“There is yet another way of spending your time and money; you may join the army; that is to say, you may hire yourself out at very high wages to go and kill men who never did you any harm. This trade is held in great honour among men, and they cannot think too highly of those who are fit for nothing better. Moreover, this profession, far from making you independent of other resources, makes them all the more necessary; for it is a point of honour in this profession to ruin those who have adopted it. It is true they are not all ruined; it is even becoming fashionable to grow rich in this as in other professions; but if I told you how people manage to do it, I doubt whether you would desire to follow their example.
