We have said that the philosophical, theological and moral tendencies of the century, which produced, with the exception of its dramatic triumphs, all its greatest literary works, are almost inextricably intermingled. Its earliest years, however, bear in theological matters rather the complexion of the previous century. Du Perron and St Francis of Sales survived until nearly the end of its first quarter, and the most remarkable works of the latter bear the dates of 1608 and later. It was not, however, till some years had passed, till the counter-Reformation had reconverted the largest and most powerful portion of the Huguenot party, and till the influence of Jansenius and Descartes had time to work, that the extraordinary outburst of Gallican theology, both in pulpit and in press, took place. The Jansenist controversy may perhaps be awarded the merit of provoking this, as far as writing was concerned. The astonishing eloquence of contemporary pulpit oratory may be set down partly to the zeal for conversion of which du Perron and de Sales had given the example, partly to the same taste of the time which encouraged dramatic performances, for the sermon and the tirade have much in common. Jansenius himself, though a Dutchman by birth, passed much time in France, and it was in France that he found most disciples. These disciples consisted in the first place of the members of the society of Port Royal des Champs, a coterie after the fashion of the time, but one which devoted itself not to sonnets or madrigals but to devotional exercises, study and the teaching of youth. This coterie early adopted the Cartesian philosophy, and the Port Royal _Logic_ was the most remarkable popular handbook of that school. In theology they adopted Jansenism, and were in consequence soon at daggers drawn with the Jesuits, according to the polemical habits of the time. The most distinguished champions on the Jansenist side were Jean Duvergier de Hauranne, abbe de St Cyran (1581-1643), and Antoine Arnauld (1560-1619), but by far the most important literary results of the quarrel were the famous _Provinciales_ of Pascal, or, to give them their proper title, _Lettres ecrites a un provincial_. Their literary importance consists, not merely in their grace of style, but in the application to serious discussion of the peculiarly polished and quiet irony of which Pascal is the greatest master the world has ever seen. Up to this time controversy had usually been conducted either in the mere bludgeon fashion of the Scaligers and Saumaises--of which in the vernacular the Jesuit Francois Garasse (1585-1631) had already contributed remarkable examples to literary and moral controversy--or else in a dull and legal style, or lastly under an envelope of Rabelaisian buffoonery such as survives to a considerable extent in the _Satire Menippee_. Pascal set the example of combining the use of the most terribly effective weapons with good humour, good breeding and a polished style.
