"But," he represented at last, "provided that I am known to you, and to the King and the Cardinal, as I see I am known to his Eminence, and as you have told me I am to his Majesty, what does it matter whether I am known to the rest?"[190] Indeed he felt such dependence to be his one resource. Some years afterwards he was called to what was, in the circumstances of the moment, the most important post in the French Government, the Ministry of Foreign Affairs. He brought to the proof a devotion to the King which had been the growth of generations; he placed at his service a ripe wisdom, a capacity for firm, constructive statesmanship, such as few of the ministers of the reign possessed. All he asked was a free hand, and firm and kingly support; for he knew that he could not have maintained himself for an hour amid the clang of policies and the machinations of intrigue. He threw himself proudly and confidently upon the loyalty of the King. He only learnt that the staff on which he leaned was a bruised reed when it went into his hand and pierced it. It was to no mistiness of mind or constitutional indecision that the vagaries of his ministry were due; but simply to the fact that his voice was drowned by the clamour of the Council, and his position sacrificed by the desertion of the King. D'Argenson could not fail to attract remark, but he was not strong enough to make himself necessary. Chauvelin had received him with curiosity and unfeigned regard; but after a time he lost the freshness of originality, and his shrinking eccentricity alone remained. The Minister treated him not unkindly. He put him off with promises, and was lavish of countenance and encouragement; and d'Argenson passed a couple of years in continual expectation of preferment, and in constant labour in the directions suggested by his patron. It was at this time that he began those researches upon foreign politics which were afterwards to prove so fruitful; and his Journal is henceforth enriched with discussions of the interests of France abroad, interesting in themselves, and often admirable for breadth and originality of view. They suggest that though d'Argenson may have been a student and a recluse, a pedant he certainly was not. One of them, presented to Chauvelin in 1734 in the form of a memoir, enables us to bring into just focus the relations between d'Argenson and his political mentor. It was criticised with his usual directness and vigour by St. Pierre, who, after pointing out its faults and admonishing the author, exhorts him not to be discouraged. "At your age," he says,[191] "I was very far from thinking so profoundly upon public affairs," and he predicts a brilliant future as the reward of his perseverance. It is in mentioning this same memoir that d'Argenson sums his opinion, repeatedly expressed, of the man who had been so long his friend. "No one knows this admirable citizen, and he does not even know himself.
