The character and conversation of these men made a deep impression upon the Pascal family. Hitherto esteemed pious, they had not yet made religion an anxious concern in their lives. Madame Périer says expressly of her brother that he had been “preserved by the special protection of God from all youthful vices, and, what was still more remarkable in the case of a mind of such strength and pride, he had never yielded to any libertinism of thought, but had always limited his curiosity to natural inquiries.” He attributed, according to her statement, this religious sobriety of mind to the instructions and example of his father, who had a great respect for religion, and who had impressed upon him from his infancy the maxim, “that whatever is the object of faith cannot be the object of reason, and still less the subject of it.” He had seen, in his father, the combination of scientific attainment with a strong reasoning power, and the maxim therefore fell with weight from his lips. And so, when he listened to the discourses of free-thinkers, young as he was— “He remained unmoved by them, and simply looked upon them as men who had adopted the false principle that the human reason is above everything, and who know nothing of the real nature of faith; so that this spirit, so great and inquisitive, which searched so carefully for the reason of everything, was at the same time submissive as a child to all the truths of religion, and this submissive simplicity predominated in him through his whole life.” {18} This is a significant extract in more ways than one. In the meantime we quote it as indicating the religious atmosphere of Pascal’s home, and the pious temper which marked him from the first. But as yet religion had not taken hold of him with an absorbing enthusiasm. It had its place in his thoughts, and this a deeply respectful place; but now, about his twenty-third year, in communication with the two friends we have mentioned, and under the same influence which had moved them so deeply, it began to lay hold of him more powerfully. He and his father and sisters read eagerly the books of St Cyran, and of Jansen, the Bishop of Ypres, whose name became so conspicuous in connection with Port Royal. A discourse by the latter on “The Reformation of the Inward Man,” and also Arnauld’s “Manual on Frequent Communion,” are supposed to have specially impressed him. In the language of his sister— “Providence led him to the study of such pious writings while he was not yet twenty-four years of age; and God so enlightened him by this course of reading, that he came to realise that the Christian religion obliges us to live only for God, and to have no other object besides Him. So clear and necessary appeared this truth to him, that he gave up for a time all his researches, renounced all other knowledge, and applied himself alone to the ‘one thing needful’ spoken of by our Lord.”
