emancipated. [Sidenote: 1647. Ætat. 24.] Pascal had hardly escaped from boyhood at this time; his invention, his patience, the admirable system he pursued of causing all his opinions to be supported by facts and actual experiment, deserved the highest praise and honour. It is mortifying to have to record that his discovery was disputed. The jesuits accused him of plagiarism from the Italians; and Descartes declared, that he had first discovered the effects produced by the weight of the atmosphere, and suggested to Pascal the experiment made on the Puy de Dôme. [Sidenote: 1651. Ætat. 28.] Pascal treated these attacks the contempt which his innocence taught him that they deserved; and published an account of his experiments without making the slightest allusion to them. Descartes was a man of eminent genius--his industry and penetration often led him to make the happiest conjectures; but, more intent on employing his bold and often fortunate imagination in the fabrication of ingenious theories than on applying himself with patience and perseverance to the discovering the secrets of nature, he sometimes threw out a happy idea, which he did not take the pains to establish as a truth and a law. The honour of invention is due to those who seize the scattered threads of knowledge which former discoverers have left, and weave it into a continuous and irrefragable web. [Sidenote: 1653. Ætat. 30.] Pascal followed up his experiments with the utmost hesitation and care, only deciding when decision became self-evident. Two Treatises, one "On the Equilibrium of Liquids," another "On the Weight of the Atmosphere," which he subsequently wrote, though they were not published till after his death, display his admirable powers of observation, and the patient zeal with which he followed up his discoveries. At the time that he wrote these treatises he was engaged on others, on geometrical subjects: he did not publish them; and some have been irrecoverably lost. Every subject then interesting to men of science employed his active mind. His name had become well known: he was consulted by all the philosophers and mathematicians of the day, who proposed questions to him; and his thoughts were sedulously dedicated to the solution of the most difficult problems. But a change meanwhile had come over his mind, and he began to turn his thoughts to other subjects, and to resolve to quit his mathematical pursuits, and to dedicate himself wholly to the practice and study of religion.
