A propos Luxembourg and William III (although the latter should be included among the statesmen), I will quote a passage from Macaulay. “In such an age (1694) bodily vigor is the most indispensable qualification for a warrior. At the battle of Landon two poor, sickly beings, who, in a rude state of society, would have been considered too puny to bear part in combats, were the souls of two great armies.” And further on: “It is probable that the two feeblest in body among the hundred and twenty thousand soldiers that fought at Neerwinden were the hunch-backed dwarf (Luxembourg) who urged forward the fiery onset of France, and the asthmatic skeleton (William III) who covered the slow retreat of England.” Napoleon was an epileptic and Lord Nelson, at the height of his efficiency, had lost an arm and an eye and what is even more remarkable was, so it is said, sick every time he went to sea or whenever the weather was exceptionally rough. General Wolfe, although only thirty-two years old, was already a man of shattered health when he undertook his famous expedition against Quebec. In spite of disheartening failures and the torture of an internal malady, he finally won the decisive victory which wrested Quebec from the French. During the battle he was twice wounded but refused to leave the field until a third bullet pierced his lung. He survived only long enough to give a final order for cutting off the retreat and breathed his last murmuring: “Now, God be praised, I will die in peace.” Let us consider for a moment what made these men pre-eminent. It was not courage. Cæsar and Napoleon were no braver than thousands of their followers. Nor was it the capacity for endurance. What then was the secret of their power? I answer unhesitatingly,—imagination. No leader has been without it and the greatest leaders are the men who have had it to a superlative degree. Napoleon recognized its mysterious sway, for it was he who said: “Imagination rules the world.” Now, imagination is the very quality we find most frequently allied to ill-health. I beg to call to your attention that with the exception of le grand Condé and possibly Napoleon, not one of these men would have passed his “medical.” It is certainly curious that the profession of arms, the most physically exacting of all professions, is the only one whose greatest examples have without exception been tainted with disease.
