So far as is known, the worldly life enjoyed by Pascal during this period can hardly be qualified as "dissipation," and certainly not as "debauchery." Even gambling may have appealed to him chiefly as affording a study of mathematical probabilities. He appears to have led such a life as any cultivated intellectual man of good position and independent means might lead and consider himself a model of probity and virtue. Not even a love-affair is laid at his door, though he is said to have contemplated marriage. But Jansenism, as represented by the religious society of Port-Royal, was morally a Puritan movement within the Church, and its standards of conduct were at least as severe as those of any Puritanism in England or America. The period of fashionable society, in Pascal's life, is however, of great importance in his development. It enlarged his knowledge of men and refined his tastes; he became a man of the world and never lost what he had learnt; and when he turned his thoughts wholly towards religion, his worldly knowledge was a part of his composition which is essential to the value of his work.
Pascal's interest in society did not distract him from scientific research; nor did this period occupy much space in what is a very short and crowded life. Partly his natural dissatisfaction with such a life, once he had learned all it had to teach him, partly the influence of his saintly sister Jacqueline, partly increasing suffering as his health declined, directed him more and more out of the world and to thoughts of eternity. And in 1654 occurs what is called his "second conversion," but which might be called his conversion simply.
He made a note of his mystical experience, which he kept always about him, and which was found, after his death, sewn into the coat which he was wearing. The experience occurred on 23 November, 1654, and there is no reason to doubt its genuineness unless we choose to deny all mystical experience. Now, Pascal was not a mystic, and his works are not to be classified amongst mystical writings; but what can only be called mystical experience happens to many men who do not become mystics. The work which he undertook soon after, the Lettres écrites à un provincial, is a masterpiece of religious controversy at the opposite pole from mysticism. We know quite well that he was at the time when he received his illumination from God in extremely poor health; but it is a commonplace that some forms of illness are extremely favourable, not only to religious illumination, but to artistic and literary composition. A piece of writing meditated, apparently without progress, for months or years, may suddenly take shape and word; and in this state long passages may be produced which require little or no retouch. I have no good word to say for the cultivation of automatic writing as the model of literary composition; I doubt whether these moments can be cultivated by the writer; but he to whom this happens assuredly has the sensation of being a vehicle rather than a maker. No masterpiece can be produced whole by such means; but neither does even the higher form of religious inspiration suffice for the religious life; even the most exalted mystic must return to the world, and use his reason to employ the results of his experience in daily life. You may call it communion with the Divine, or you may call it a temporary crystallisation of the mind. Until science can teach us to reproduce such phenomena at will, science cannot claim to have explained them; and they can be judged only by their fruits.
From that time until his death, Pascal was closely associated with the society of Port-Royal which his sister Jacqueline, who predeceased him, had joined as a religieuse; the society was then fighting for its life against the Jesuits. Five propositions, judged by a committee of cardinals and theologians at Rome to be heretical, were found to be put forward in the work of Jansenius; and the society of Port-Royal, the representative of Jansenism among devotional communities, suffered a blow from which it never revived. It is not the place here to review the bitter controversy and conflict; the best account, from the point of view of a critic of genius who took no side, who was neither Jansenist nor Jesuit, Christian nor infidel, is that in the great book of Sainte-Beuve, Port-Royal. And in this book the parts devoted to Pascal himself are among the most brilliant pages of criticism that Sainte-Beuve ever wrote. It is sufficient to notice that the next occupation of Pascal, after his conversion, was to write these eighteen "Letters," which as prose are of capital importance in the foundation of French classical style, and which as polemic are surpassed by none, not by Demosthenes, or Cicero, or Swift. They have the limitation of all polemic and forensic: they persuade, they seduce, they are unfair. But it is also unfair to assert that, in these Letters to a Provincial, Pascal was attacking the Society of Jesus in itself. He was attacking rather a particular school of casuistry which relaxed the requirements of the Confessional; a school which certainly flourished amongst the Society of Jesus at that time, and of which the Spaniards Escobar and Molina are the most eminent authorities. He undoubtedly abused the art of quotation, as a polemical writer can hardly help but do; but there were abuses for him to abuse; and he did the job thoroughly. His Letters must not be called theology. Academic theology was not a department in which Pascal was versed; when necessary, the fathers of Port-Royal came to his aid. The Letters are the work of one of the finest mathematical minds of any time, and of a man of the world who addressed, not theologians, but the world in general—all of the cultivated and many of the less cultivated of the French laity; and with this public they made an astonishing success.
During this time Pascal never wholly abandoned his scientific interests. Though in his religious writings he composed slowly and painfully, and revised often, in matters of mathematics his mind seemed to move with consummate natural ease and grace. Discoveries and inventions sprang from his brain without effort; among the minor devices of this later period, the first omnibus service in Paris is said to owe its origin to his inventiveness. But rapidly failing health, and absorption in the great work he had in mind, left him little time and energy during the last two years of his life.
The plan of what we call the Pensées formed itself about 1660. The completed book was to have been a carefully constructed defence of Christianity, a true Apology and a kind of Grammar of Assent, setting forth the reasons which will convince the intellect. As I have indicated before, Pascal was not a theologian, and on dogmatic theology had recourse to his spiritual advisers. Nor was he indeed a systematic philosopher. He was a man with an immense genius for science, and at the same time a natural psychologist and moralist. As he was a great literary artist, his book would have been also his own spiritual autobiography; his style, free from all diminishing idiosyncrasies, was yet very personal. Above all, he was a man of strong passions; and his intellectual passion for truth was reinforced by his passionate dissatisfaction with human life unless a spiritual explanation could be found.
We must regard the Pensées as merely the first notes for a work which he left far from completion; we have, in Sainte-Beuve's words, a tower of which the stones have been laid on each other, but not cemented, and the structure unfinished. In early years his memory had been amazingly retentive of anything that he wished to remember; and had it not been impaired by increasing illness and pain, he probably would not have been obliged to set down these notes at all. But taking the book as it is left to us, we still find that it occupies a unique place in the history of French literature and in the history of religious meditation.
To understand the method which Pascal employs, the reader must be prepared to follow the process of the mind of the intelligent believer. The Christian thinker—and I mean the man who is trying consciously and conscientiously to explain to himself the sequence which culminated in faith, rather than the public apologist—proceeds by rejection and elimination. He finds the world to be so and so; he finds its character inexplicable by any non-religious theory; among religions he finds Christianity, and Catholic Christianity, to account most satisfactorily for the world
