"Our great Hurtado de Mendoza," said the father, "will satisfy you on that point in a twinkling. 'If a gentleman,' says he, in a passage cited by Diana, 'who is challenged to fight a duel, is well known to have no religion, and if the vices to which he is openly and unscrupulously addicted are such as would lead people to conclude, in the event of his refusing to fight, that he is actuated, not by the fear of God, but by cowardice, and induce them to say of him that he was a _hen_, and not a man--_gallina, et non vir_; in that case he may, to save his honor, appear at the appointed spot--not, indeed, with the express intention of fighting a duel, but merely with that of defending himself, should the person who challenged him come there unjustly to attack him. His action in this case, viewed by itself, will be perfectly indifferent; for what moral evil is there in one's stepping into a field, taking a stroll in expectation of meeting a person, and defending one's self in the event of being attacked? And thus the gentleman is guilty of no sin whatever; for, in fact, it cannot be called accepting a challenge at all, his intention being directed to other circumstances, and the acceptance of a challenge consisting in an express intention to fight, which we are supposing the gentleman never had.'" The humorous irony of Pascal, in the "Provincial Letters," plays like the diffusive sheen of an aurora borealis over the whole surface of the composition. It does not often deliver itself startlingly in sudden discharges as of lightning. You need to school your sense somewhat, not to miss a fine effect now and then. Consider the broadness and coarseness in pleasantry, that, before Pascal, had been common, almost universal, in controversy, and you will better understand what a creative touch it was of genius, of feeling, and of taste, that brought into literature the far more than Attic, the ineffable Christian, purity of that wit and humor in the "Provincial Letters" which will make these writings live as long as men anywhere continue to read the productions of past ages. Erasmus, perhaps, came the nearest of all modern predecessors to anticipating the purified pleasantry of Pascal. It will be interesting and instructive to see Pascal's own statement of his reasons for adopting the bantering style which he did in the "Provincial Letters," as well as of the sense of responsibility to be faithful and fair, under which he wrote. Pascal says:
