When both were seventeen the pair parted for a while. Luc must choose one of the only two professions open to his caste—the Church or the Army. The Church would not do, because, boy though he was, he was already philosopher and thinker—ay, in the noblest sense of the word—free-thinker too. Then it must be the Army! Picture this new subaltern of the King’s Own Regiment, in the loveliest pale grey uniform, faced with Royal blue, with the most splendid braidings, and the very buttonholes sewn with gold silk, with his tall, boyish figure, his handsome face, his ‘proud and pensive grace’—for all the world like the soldier-hero of a woman’s novel. But he was already something very different from that. The handsome face bespoke a noble nature, ambitious for all great things, strong and ready to begin the world, to play his part therein if it be the part of a man of Deeds alone—or if the Deeds be but foundation for the Thoughts.

His first campaign was in Italy in 1733 with Marshal Villars, who was on his last. Italy! the land of dreams! The boy was filled with splendid visions of following Hannibal across the mountains—with young sanguine hopes of gloriously doing his duty and meeting immediate, glorious rewards. For three years he knew the intoxication—and the horrors—of a victorious campaign. And then of a sudden he found himself condemned at one-and-twenty to the vicious idleness, the low pleasures, and the deadening routine of a garrison life. The rich officers were of course drawn by that magnet, the Court, to keep up their military studies and prepare for the next war by dancing attendance on women and flattering the Minister and the King at Versailles. The poor ones remained on duty—with not enough of it to keep them out of mischief, and with, for the most part, debased tastes, because their intellectual limitations precluded them from higher.

The contamination of that useless existence even a Vauvenargues did not wholly escape. For a brief while he was as other men are. But the pleasures of a garrison town could not long hold such a nature as his. Already—he was but twenty-two—he had that love of solitude which, says a great German philosopher, is welcomed or avoided as a man’s personal value is great or small. Already—at an age when other men scarcely realise they have a soul—this man was dominated by the idea of its value and dignity; and deep within him was the passion and resolution to exercise to the full its powers and possibilities.

With his companions he was wholly simple, natural, and friendly—without the faintest taint of that conscious superiority which makes many good people at once useless as a moral influence and objectionable as companions. ‘Father,’ his brother officers used to call him. Marmontel said ‘he held all our souls in his hands.’ He soon resumed, by correspondence, his friendship with Victor Mirabeau; and in their discussions on love—the view he takes of this passion is always a sure test of a man’s character—each letter-writer showed the yawning gulf that divided him from the other.

If Vauvenargues ever met the woman worthy to hold his heart, to be, in the finest and highest understanding of those words, his companion and completion, is not known. He writes of love as if he had felt it. But to some pure souls—as to a Milton and a St. John the Divine—are revealed in visions the Eden and the New Jerusalem wherein they never walked. Vauvenargues’ letters to Mirabeau treat of the subject with such an exquisite dignity and refinement—with such noble silences—that there is at least no doubt that if he never found the woman who would have realised his ideals, he was spared the bitterness of loving one who broke them.

Cousin Victor easily perceived that this thoughtful young soldier was fitted for something widely different from the life of a garrison town. Come up to Paris, then! Take up letters as a career! Win the smiles of the Court, and a pension from the Privy Purse! But Vauvenargues not only preferred literature to the sham called literary fame, but he loved his own profession.

Thinker as nature had made him, thinker, moralist, aphorist as he has come down the ages, he was first of all a man of action, and so sound in thought because he was so strong in deeds. All his maxims were ‘hewn from life.’ When the death of the Emperor Charles VI. in 1740 shook the kingdoms of Europe as a child shakes its marbles in a bag, Luc de Vauvenargues shouldered his knapsack and went out to Bohemia under the command of Belle-Isle. Ready to dare and to do, brave, young, high-spirited, knowing no career more glorious than arms, he looked round him and drew from keen experience his views of the world.

The philosopher in a study, weighing the pros and cons of motives he knows by hearsay, of deeds of which he has read, of passions he has never felt, may be a very fine thinker, but will hardly be chosen as a sound guide to practice.

The explorer who has faced the torrent and the mountain, the burning sun of the desert, hunger and cold and thirst, who has himself fought with beasts at Ephesus, will have a knowledge of the country he has discovered, which no books and lectures, no geographical or topographical knowledge can ever give to the cleverest student at home. The worth and the use of Vauvenargues’ axioms on life lie largely in the fact that he had been there himself.

The very brief triumph of the capture of Prague in 1742 was succeeded by the horrors of the great mid-winter march from Prague to Egra. The King’s Own suffered terribly. Death, defeat, famine, Vauvenargues knew not as names but as realities. In the spring of 1742 he had lost a young comrade, de Seytres, and wrote an éloge of him. Its immature and stilted style gives little idea of the warm feeling it clothed. Morley speaks of Vauvenargues’ ‘patient sweetness and equanimity’ as a friend; and records how hardship made him ‘not sour,’ but wise and tender. All through that fearful march, in this strange soldier’s knapsack were the manuscripts of ‘Discourses on Fame and Pleasure,’ ‘Counsels to a Young Man,’ and a ‘Meditation on Faith.’ Of many of his maxims on patience and the brave endurance of suffering, he must have found at this time cruel personal need.
