The Law of Nations. Emer de Vattel

will be necessary in order to give a complete solution to the celebrated question, whether a man may quit his country or the society of which he is a member. 1. The children are bound by natural ties to the society in which they were born: they are under an obligation to shew themselves grateful for the protection it has afforded to their fathers, and are in a great measure indebted to it for their birth and education. They ought therefore to love it, as we have already shewn (§122),—to express a just gratitude to it, and requite its services as far as possible by serving it in turn. We have observed above (§212), that they have a right to enter <104> into the society of which their fathers were members. But every man is born free; and the son of a citizen, when come to the years of discretion, may examine whether it be convenient for him to join the society for which he was destined by his birth. If he does not find it advantageous to remain in it, he is at liberty to quit it on making it a compensation for what it has done in his favour,^* and preserving, as far as his new engagements will allow him, the sentiments of love and gratitude he owes it. A man’s obligations to his natural country may, however, change, lessen, or entirely vanish, according as he shall have quitted it lawfully, and with good reason, in order to choose another, or has been banished from it deservedly or unjustly, in due form of law, or by violence.

      2. As soon as the son of a citizen attains the age of manhood, and acts as a citizen, he tacitly assumes that character; his obligations, like those of others who expressly and formally enter into engagements with society, become stronger and more extensive: but the case is very different with respect to him of whom we have been speaking. When a society has not been formed for a determinate time, it is allowable to quit it, when that separation can take place without detriment to the society. A citizen may therefore quit the state of which he is a member, provided it be not in such a conjuncture when he cannot abandon it without doing it a visible injury. But we must here draw a distinction between what may in strict justice be done, and what is honourable and conformable to every duty,—in a word, between the internal and the external obligation. Every man has a right to quit his country, in order to settle in any other, when by that step he does not endanger the welfare of his country. But a good citizen will never determine on such a step without necessity, or without very strong reasons. It is taking a dishonourable advantage of our liberty, to quit our associates upon slight pretences, after having derived considerable advantages from them: and this is the case of every citizen with respect to his country.

      3. As to those who have the cowardice to abandon their country in a time of danger, and seek to secure themselves instead of defending it,— they manifestly violate the social compact, by which all the contracting parties engaged to defend themselves in an united body, and in concert: they are infamous deserters whom the state has a right to punish severely.^* <105>

§221. How a person may absent himself for a time.

      In a time of peace and tranquillity, when the country has no actual need of all her children, the very welfare of the state, and that of the citizens, requires that every individual be at liberty to travel on business, provided that he be always ready to return, whenever the public interest recalls him. It is not presumed that any man has bound himself to the society of which he is a member, by an engagement never to leave the country when the interest of his affairs requires it, and when he can absent himself without injury to his country.

§222. Variation of the political laws in this respect.

       These must be obeyed.

      The political laws of nations vary greatly in this respect. In some nations, it is at all times, except in case of actual war, allowed to every citizen to absent himself, and even to quit the country altogether, whenever he thinks proper, without alleging any reason for it. This liberty, contrary in its own nature to the welfare and safety of society, can no where be tolerated but in a country destitute of resources and incapable of supplying the wants of its inhabitants. In such a country there can only be an imperfect society; for civil society ought to be capable of enabling all its members to procure by their labour and industry all the necessaries of life:—unless it effects this, it has no right to require them to devote themselves entirely to it. In some other states, every citizen is left at liberty to travel abroad on business, but not to quit his country altogether, without the express permission of the sovereign. Finally, there are states where the rigour of the government will not permit any one whatsoever to go out of the country, without passports in form, which are even not granted without great difficulty. In all these cases it is necessary to conform to the laws, when they are made by a lawful authority. But in the last-mentioned case, the sovereign abuses his power, and reduces his subjects to an insupportable slavery, if he refuses them permission to travel for their own advantage, when he might grant it to them without inconvenience, and without danger to the state. Nay it will presently appear, that, on certain occasions, he cannot, under any pretext, detain persons who wish to quit the country with the intention of abandoning it for ever.

§223. Cases in which a citizen has a right to quit his country.

      There are cases in which a citizen has an absolute right to renounce his country, and abandon it entirely,—a right, founded on reasons derived from the very nature of the social compact.—1. If the citizen cannot procure subsistence in his own country, it is undoubtedly lawful for him to seek it elsewhere. For political or civil society being entered into only with a view of facilitating to each of its members the means of supporting himself, and of living in happiness and safety, it would be absurd to pretend that a member, whom it cannot furnish with such things as are most necessary, has not a right to leave it.

      2. If the body of the society, or he who represents it, absolutely fail to discharge their obligations towards a citizen, the latter may withdraw himself. For if one of the contracting parties does not observe his engagements, the other is no longer bound to fulfil his; for the contract is reciprocal between the society and <106> its members. It is on the same principle also that the society may expel a member who violates its laws.

      3. If the major part of the nation, or the sovereign who represents it, attempt to enact laws relative to matters in which the social compact cannot oblige every citizen to submission, those who are averse to these laws have a right to quit the society, and go settle elsewhere. For instance, if the sovereign, or the greater part of the nation, will allow but one religion in the state, those who believe and profess another religion have a right to withdraw, and to take with them their families and effects. For they cannot be supposed to have subjected themselves to the authority of men, in affairs of conscience;^* and if the society suffers and is weakened by their departure, the blame must be imputed to the intolerant party: for it is they who fail in their observance of the social compact,— it is they who violate it, and force the others to a separation. We have elsewhere touched upon some other instances of this third case,—that of a popular state wishing to have a sovereign (§33),—and that of an independent nation taking the resolution to submit to a foreign power (§195).

§224. Emigrants.

      Those who quit their country for any lawful reason, with a design to settle elsewhere, are called emigrants, and take their families and property with them.

§225. Sources of their right.

      Their right to emigrate may arise from several sources. 1. In the cases we have just mentioned (§223), it is a natural right, which is certainly reserved to each individual in the very compact itself by which civil society was formed.

      2. The liberty of emigration may, in certain cases, be secured to the citizens by a fundamental law of the state. The citizens of Neufchatel and Valangin in Switzerland may quit the country and carry off their effects at their own pleasure, without even paying any duties.
