It is true that M. Zevort endeavours to illustrate d'Argenson's political principles from his own "Essai de l'exercice du tribunal européen par la France seule;" but it may very well be doubted whether this piece possesses the importance which has been attached to it. It was written shortly after, or possibly before, the fall of Chauvelin, and at least seven years before d'Argenson's accession to the Ministry. In November 1737, when it appeared in manuscript, France was at peace, Fleury was still Minister, the war between Spain and England had not broken out, the old House of Austria was not yet extinct, and Frederick was still Prince Royal of Prussia. In the interval the face of Europe had wholly changed. Moreover the "Essai" consists of no more than half-a-dozen widely printed pages, placed at the end of the 1764 edition of the "Considérations,"[260] and omitted altogether from that of 1784. It contains a few loose remarks about Russia and the northern powers, with some views upon Spain and Austria which are the commonplaces of d'Argenson's Journal. Almost the only remarkable feature are some significant words upon the position of England, which show that the shadow of 1763 was already falling across the path of France.[261] Indeed the piece appears to be really nothing more than a brief academic essay, written, as we learn from the title-page of the manuscripts in the Library of the Arsenal, as a note upon St. Pierre's "Projet de la Paix Perpétuelle."[262] That the author regarded it as of small importance is clear from his failure to exhibit in his Journal any further affection for its leading idea, the exercise of international arbitration by France alone; his subsequent criticism of Fleury is little more than a consistent denial of it; and we can point to at least one passage where its central principle is categorically rejected.[263] It is true that the conception of a benevolent arbitration exercised by France remained as a shadowy and distant ideal before d'Argenson's mind; but that it had ever any serious influence upon his practical ideas of policy there is no evidence to suggest. Even if it be admitted, with M. Zevort, that these were "the ideas, some ingenious, others chimerical, almost all beyond realisation, which d'Argenson nourished in 1737," it may be denied, with some distinctness, that "he brought them to the ministry in 1744."[264]
