up as the spirit of the time. The Jesuits were the great official instructors of France for the first half of the eighteenth century. In 1764 the order was thrust forth from the country, and they left behind them an army of the bitterest enemies that Christianity has ever had. To do them justice, they were destroyed by weapons which they had themselves supplied. The intelligence which they had developed and sharpened, turned inevitably against the incurable faults in their own system. They were admirable teachers of mathematics. Condorcet, instructed by the Jesuits at Rheims, was able when he was only fifteen years old to go through such performances in analysis as to win especial applause from illustrious judges like D’Alembert and Clairaut. It was impossible, however, for Jesuits, as it has ever been for all enemies of movement, to constrain within prescribed limits the activity which has once been effectively stirred. Mathematics has always been in the eyes of the Church a harmless branch of knowledge, but the mental energy that mathematics first touched is sure to turn itself by and by to more complex and dangerous subjects in the scientific hierarchy.

At any rate, Condorcet’s curiosity was very speedily drawn to problems beyond those which geometry and algebra pretend to solve. ‘For thirty years,’ he wrote in 1790, ‘I have hardly ever passed a single day without meditating on the political sciences.’[1] Thus, when only seventeen, when the ardour of even the choicest spirits is usually most purely intellectual, moral and social feeling was rising in Condorcet to that supremacy which it afterwards attained in him to so admirable a degree. He wrote essays on integral calculus, but he was already beginning to reflect upon the laws of human societies and the conditions of moral obligation. At the root of Condorcet’s nature was a profound sensibility of constitution. One of his biographers explains his early enthusiasm for virtue and human welfare as the conclusion of a kind of syllogism. It is possible that the syllogism was only the later shape into which an instinctive impulse threw itself by way of rational entrenchment. His sensibility caused Condorcet to abandon the barbarous pleasures of the chase, which had at first powerfully attracted him.[2] To derive delight from what inflicts pain on any sentient creature revolted his conscience and offended his reason, because he perceived that the character which does not shrink from associating its own joy with the anguish of another, is either found or left mortally blunted to the finest impressions of humanity.

It is thus assured that from the beginning Condorcet was unable to satisfy himself with the mere knowledge of the specialist, but felt the necessity of placing social aims at the head and front of his life, and of subordinating to them all other pursuits. That he values knowledge only as a means to social action, is one of the highest titles to our esteem that any philosopher can have. Such a temper of mind has penetrated no man more fully than Condorcet, though there are other thinkers to whom time and chance have been more favourable in making that temper permanently productive. There is a fine significance in his words, after the dismissal of the great and virtuous Turgot from office: ‘We have had a delightful dream, but it was too brief. Now I mean to apply myself to geometry. It is terribly cold to be for the future labouring only for the gloriole, after flattering oneself for a while that one was working for the public weal.’ It is true that a geometer, too, works for the public weal; but the process is tardier, and we may well pardon an impatience that sprung of reasoned zeal for the happiness of mankind. There is something much more attractive about Condorcet’s undisguised disappointment at having to exchange active public labour for geometrical problems, than in the affected satisfaction conventionally professed by statesmen when driven from place to their books. His correspondence shows that, even when his mind seemed to be most concentrated upon his special studies, he was incessantly on the alert for every new idea, book, transaction, that was likely to stimulate the love of virtue in individuals, or to increase the strength of justice in society. It would have been in one sense more fortunate for him to have cared less for high social interests, if we remember the contention of his latter days and the catastrophe which brought them to a frightful close. But Condorcet was not one of those natures who can think it happiness to look passively out from the tranquil literary watch-tower upon the mortal struggles of a society in revolution. In measuring other men of science—as his two volumes of Éloges abundantly show—one cannot help being struck by the eagerness with which he seizes on any trait of zeal for social improvement, any signal of anxiety that the lives and characters of our fellows should be better worth having. He was himself too absolutely possessed by this social spirit to have flinched from his career, even if he had foreseen the martyrdom which was to consummate it. ‘You are very happy,’ he once wrote to Turgot, ‘in your passion for the public good and your power to satisfy it; it is a great consolation, and of an order very superior to that of study.’[3]

In 1769, at the age of six-and-twenty, Condorcet became connected with the Academy, to the mortification of his relations, who hardly pardoned him for not being a captain of horse as his father had been before him. About the same time, or a little later, he performed a pilgrimage of a kind that could hardly help making a mark upon a character so deeply impressible. In company with D’Alembert he went to Ferney and saw Voltaire.[4] To the position of Voltaire in Europe in 1770 there has never been any other man’s position in any age wholly comparable. It is true that there had been one or two of the great popes, and a great ecclesiastic like St. Bernard, who had exercised a spiritual authority, pretty universally submitted to, or even spontaneously invoked, throughout western Europe. But these were the representatives of a powerful organisation and an accepted system. Voltaire filled a place before men’s eyes in the eighteenth century as conspicuous and as authoritative as that of St. Bernard in the twelfth. The difference was that Voltaire’s place was absolutely unofficial in its origin, and indebted to no system nor organisation for its maintenance. Again, there have been others, like Bacon or Descartes, destined to make a far more permanent contribution to the ideas which have extended the powers and elevated the happiness of men; but these great spirits for the most part laboured for the generation that followed them, and won comparatively slight recognition from their own age. Voltaire during his life enjoyed to the full not only the admiration that belongs to the poet, but something of the veneration that is paid to the thinker, and even something of the glory usually reserved for captains and
