Although not the grandson of the duke, as has been erroneously supposed,[38] Saint-Simon would naturally have inherited his titles and property. They were lost to him, however, through the quarrel of his father with the duke. The titles he lost were those of a grandee of Spain and a duke of France, while the property he would have inherited yielded an annual income of 500,000 francs. “I have lost the titles and the fortune of the Duke of Saint-Simon,” he writes, “but I have inherited his passion for glory.” This was manifested in a singular way when he was only sixteen years of age. That he might not forget the grand destiny in store for him, he ordered his servant to awaken him every morning with the words, “Arise, Monsieur le Comte, you have grand deeds to perform.” Saint-Simon had already entered the army at this time, and the year afterwards went to America and fought in the War of the Revolution under Washington. He took part in the siege of Yorktown and witnessed the surrender of Lord Cornwallis. He distinguished himself for bravery on this occasion, and received honorable recognition of his gallant conduct from the Society of the Cincinnati. Upon his return to France, he was made colonel of the Regiment of Aquitaine at the early age of twenty-three. But he soon resigned his position and abandoned all hopes of a military career, although his prospects were certainly brilliant. In speaking of his sojourn in the United States, he says: “I occupied myself much more with political science than military tactics. The war in itself did not interest me, but the purpose of the war interested me exceedingly, and this interest enabled me to endure its hardships without repugnance. I desire the attainment of the purpose, I was accustomed to say to myself, and I ought not to rebel against the means thereto.... My vocation was not that of a soldier; I was drawn towards a very different, indeed, I may say, diametrically opposite, kind of activity. The life purpose which I set before me was to study the movements of the human mind, in order that I might then labor for the perfection of civilization. From that time forward I devoted myself to this work without reserve; to it I consecrated my entire life.”[39] Saint-Simon was taken prisoner by the British when returning to France in the _Ville de Paris_, and carried to Jamaica, where he was detained until the close of the war. In returning to Europe he visited Mexico, and there made an attempt to carry out one of the magnificent plans for the advancement of mankind which he had been revolving in his mind. He endeavored to interest the viceroy in a project for building a canal to unite the Atlantic with the Pacific. While his exertions were unsuccessful, it is interesting to note that one who drew his inspiration largely from Saint-Simon—viz., De Lesseps—may yet execute his plan.
