For why should the law of justice, which states that reasonable promises must be kept, be more inviolable for him than any other laws? 177. All these three dogmas, albeit a little different from one another, namely, (1) that the nature of justice is arbitrary, (2) that it is fixed, but it is not certain that God will observe it, and finally (3) that the justice we know is not that which he observes, destroy the confidence in God that gives us tranquillity, and the love of God that makes our happiness. There is nothing to prevent such a God from behaving as a tyrant and an enemy of honest folk, and from taking pleasure in that which we call evil. Why should he not, then, just as well be the evil principle of the Manichaeans as the single good principle of the orthodox? At least he would be neutral and, as it were, suspended between the two, or even sometimes the one and sometimes the other. That would be as if someone were to say that Oromasdes and Arimanius reign in turns, according to which of the two is the stronger or the more adroit. It is like the saying of a certain Moghul woman. She, so it seems, having heard it said that formerly under Genghis Khan and his successors her nation had had dominion over most [238] of the North and East, told the Muscovites recently, when M. Isbrand went to China on behalf of the Czar, through the country of those Tartars, that the god of the Moghuls had been driven from Heaven, but that one day he would take his own place again. The true God is always the same: natural religion itself demands that he be essentially as good and wise as he is powerful. It is scarcely more contrary to reason and piety to say that God acts without cognition, than to maintain that he has cognition which does not find the eternal rules of goodness and of justice among its objects, or again to say that he has a will such as heeds not these rules.
