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.
