Quoting Adam Smith in “Wealth of Nations” Chap. Seven:
… Under all absolute governments there is more liberty in the capital than in any other part of the country. The sovereign himself can never have either interest or inclination to pervert the order of justice, or to oppress the great body of the people. In the capital his presence over-awes more or less all his inferior officers, who in the remoter provinces, from whence the complaints of the people are less likely to reach him, can exercise their tyranny with much more safety. But the European colonies in America are more remote than the most distant provinces of the greatest empires which had ever been known before. The government of the English colonies is perhaps the only one which, since the world began, could give perfect security to the inhabitants of so very distant a province. The administration of the French colonies, however, has always been conducted with more gentleness and moderation than that of the Spanish and Portugese. This superiority of conduct is suitable both to the character of the French nation, and to what forms the character of every nation, the nature of their government, which though arbitrary and violent in comparison with that of Great Britain, is legal and free in comparison with those of Spain and Portugal.It is in the progress of the North American colonies, however, that the superiority of the English policy chiefly appears. The progress of the sugar colonies of France has been at least equal, perhaps superior, to that of the greater part of those of England, and yet the sugar colonies of England enjoy a free government nearly of the same kind with that which takes place in her colonies of North America. But the sugar colonies of France are not discouraged, like those of England, from refining their own sugar; and, what is of still greater importance, the genius of their government naturally introduces a better management of their negro slaves.
In all European colonies the culture of the sugar-cane is carried on by negro slaves. The constitution of those who have been born in the temperate climate of Europe could not, it is supposed, support the labour of digging the ground under the burning sun of the West Indies; and the culture of the sugar-cane, as it is managed at present, is all hand labour, though, in the opinion of many, the drill plough might be introduced into it with great advantage. But, as the profit and success of the cultivation which is carried on by means of cattle, depend very much upon the good management of those cattle, so the profit and success of that which is carried on by slaves must depend equally upon the good management of those slaves; and in the good management of their slaves the French planters, I think it is generally allowed, are superior to the English. The law, so far as it gives some weak protection to the slave against the violence of his master, is likely to be better executed in a colony where the government is in a great measure arbitrary than in one where it is altogether free. In every country where the unfortunate law of slavery is established, the magistrate, when he protects the slave, intermeddles in some measure in the management of the private property of the master; and, in a free country, where the master is perhaps either a member of the colony assembly, or an elector of such a member, he dare not do this but with the greatest caution and circumspection. The respect which he is obliged to pay to the master renders it more difficult for him to protect the slave. But in a country where the government is in a great measure arbitrary, where it is usual for the magistrate to intermeddle even in the management of the private property of individuals, and to send them, perhaps, a lettre de cachet if they do not manage it according to his liking, it is much easier for him to give some protection to the slave; and common humanity naturally disposes him to do so. The protection of the magistrate renders the slave less contemptible in the eyes of his master, who is thereby induced to consider him with more regard, and to treat him with more gentleness. Gentle usage renders the slave not only more faithful, but more intelligent, and therefore, upon a double account, more useful. He approaches more to the condition of a free servant, and may possess some degree of integrity and attachment to his master’s interest, virtues which frequently belong to free servants, but which never can belong to a slave who is treated as slaves commonly are in countries where the master is perfectly free and secure.
That the condition of a slave is better under an arbitrary than under a free government is, I believe, supported by the history of all ages and nations. In the Roman history, the first time we read of the magistrate interposing to protect the slave from the violence of his master is under the emperors. When Vedius Pollio, in the presence of Augustus, ordered one of his slaves, who had committed a slight fault, to be cut into pieces and thrown into his-fish pond in order to feed his fishes, the emperor commanded him, with indignation, to emancipate immediately, not only that slave, but all the others that belonged to him. [Footnote] Under the republic no magistrate could have had authority enough to protect the slave, much less to punish the master.
