• Différence entre J.-C. et Mahomet. Mahomet non prédit, J.-C. prédit. Mahomet en tuant, J.-C. en faisant tuer les siens. Mahomet en défendant de lire, les apôtres en ordonnant de lire. Enfin cela est si contraire que si Mahomet a pris la voie de réussir humainement, J.-C. a pris celle de périr humainement et qu'au lieu de conclure que puisque Mahomet a réussi, J.-C. a bien pu réussir, il faut dire que puisque Mahomet a réussi, J.-C. devait périr.
  • The difference between Jesus Christ and Mahomet.—Mahomet was not foretold; Jesus Christ was foretold.

    Mahomet slew; Jesus Christ caused His own to be slain.

    Mahomet forbade reading; the Apostles ordered reading.

    In fact the two are so opposed, that if Mahomet took the way to succeed from a worldly point of view, Jesus Christ, from the same point of view, took the way to perish. And instead of concluding that, since Mahomet succeeded, Jesus Christ might well have succeeded, we ought to say that since Mahomet succeeded, Jesus Christ should have failed.(598)

• Qu’est-ce donc que nous crie cette avidité et cette impuissance, sinon qu’il y a eu autrefois en l’homme un véritable bonheur dont il ne lui reste maintenant que la marque et la trace toute vide, qu’il essaye inutilement de remplir de tout ce qui l’environne, en cherchant dans les choses absentes le secours qu’il n’obtient pas des présentes, et que les unes et les autres sont incapables de lui donner, parce que ce gouffre infini ne peut être rempli que par un objet infini et immuable, c'est-à-dire que par Dieu même. (425)
  • Translation: What does this craving, and this helplessness, proclaim but that there was once in man a true happiness, of which all that now remains is the empty print and trace? This he tries in vain to fill with everything around him, seeking in things that are not there the help he cannot find in those that are, though none can help, since this infinite abyss can be filled only with an infinite and immutable object, in other words by God himself.
