The definite theories of jurists are scarcely nearer the truth in this point than the opinions of the multitude. To begin with the views of the Roman lawyers, we find them inconsistent with the true history of moral and legal progress. One class of contracts, in which the plighted faith of the contracting parties was the only material ingredient, they specifically denominated Contracts juris gentium, and though these contracts were undoubtedly the latest born into the Roman system, the expression employed implies, if a definite meaning be extracted from it, that they were more ancient than certain other forms of engagement treated of in Roman law, in which the neglect of a mere technical formality was as fatal to the obligation as misunderstanding or deceit. But then the antiquity to which they were referred was vague, shadowy, and only capable of being understood through the Present; nor was it until the language of the Roman lawyers became the language of an age which had lost the key to their mode of thought that a "Contract of the Law of Nations" came to be distinctly looked upon as a Contract known to man in a State of Nature. Rousseau adopted both the juridical and the popular error. In the Dissertation on the effects of Art and Science upon Morals, the first of his works which attracted attention and the one in which he states most unreservedly the opinions which made him the founder of a sect, the veracity and good faith attributed to the ancient Persians are repeatedly pointed out as traits of primitive innocence which have been gradually obliterated by civilisation; and at a later period he found a basis for all his speculations in the doctrine of an original Social Contract. The Social Contract or Compact is the most systematic form which has ever been assumed by the error we are discussing. It is a theory which, though nursed into importance by political passions, derived all its sap from the speculations of lawyers. True it certainly is that the famous Englishmen, for whom it had first had attraction, valued it chiefly for its political serviceableness, but, as I shall presently attempt to explain, they would never have arrived at it, if politicians had not long conducted their controversies in legal phraseology. Nor were the English authors of the theory blind to that speculative amplitude which recommended it so strongly to the Frenchmen who inherited it from them. Their writings show they perceived that it could be made to account for all social, quite as well as for all political phenomena. They had observed the fact, already striking in their day, that of the positive rules obeyed by men, the greater part were created by Contract, the lesser by Imperative Law. But they were ignorant or careless of the historical relation of these two constituents of jurisprudence. It was for the purpose, therefore, of gratifying their speculative tastes by attributing all jurisprudence to a uniform source, as much as with the view of eluding the doctrines which claimed a divine parentage for Imperative Law that they devised the theory that all Law had its origin in Contract. In another stage of thought, they would have been satisfied to leave their theory in the condition of an ingenious hypothesis or a convenient verbal formula. But that age was under the dominion of legal superstitions. The State of Nature had been talked about till it had ceased to be regarded as paradoxical, and hence it seemed easy to give a fallacious reality and definiteness to the contractual origin of Law by insisting on the Social Compact as a historical fact.
Our own generation has got rid of these erroneous juridical theories, partly by outgrowing the intellectual state to which they belong, and partly by almost ceasing to theorise on such subjects altogether. The favourite occupation of active minds at the present moment, and the one which answers to the speculations of our forefathers on the origin of the social state, is the analysis of society as it exists and moves before our eyes; but, through omitting to call in the assistance of history, this analysis too often degenerates into an idle exercise of curiosity, and is especially apt to incapacitate the inquirer for comprehending states of society which differ considerably from that to which he is accustomed. The mistake of judging the men of other periods by the morality of our own day has its parallel in the mistake of supposing that every wheel and bolt in the modern social machine had its counterpart in more rudimentary societies.
Such impressions ramify very widely, and masque themselves very subtly, in historical works written in the modern fashion; but Ifind the trace of their presence in the domain of jurisprudence in the praise which is frequently bestowed on the little apologue of Montesquieu concerning the Troglodytes, inserted in the Lettres Persanes. The Troglodytes were a people who systematically violated their Contracts, and so perished utterly.
