Pierre continued glancing through the humble little book, listening to all it told him of sovereign Science. She cannot become bankrupt, for she does not promise the absolute, she is simply the progressive conquest of truth. Never has she pretended that she could give the whole truth at one effort, that sort of edifice being precisely the work of metaphysics, of revelation, of faith. The /role/ of Science, on the contrary, is only to destroy error as she gradually advances and increases enlightenment. And thus, far from becoming bankrupt, in her march which nothing stops, she remains the only possible truth for well-balanced and healthy minds. As for those whom she does not satisfy, who crave for immediate and universal knowledge, they have the resource of seeking refuge in no matter what religious hypothesis, provided, if they wish to appear in the right, that they build their fancy upon acquired certainties. Everything which is raised on proven error falls. However, although religious feeling persists among mankind, although the need of religion may be eternal, it by no means follows that Catholicism is eternal, for it is, after all, but one form of religion, which other forms preceded and which others will follow. Religions may disappear, but religious feeling will create new ones even with the help of Science. Pierre thought of that alleged repulse of Science by the present-day awakening of mysticism, the causes of which he had indicated in his book: the discredit into which the idea of liberty has fallen among the people, duped in the last social reorganisation, and the uneasiness of the /elite/, in despair at the void in which their liberated minds and enlarged intelligences have left them. It is the anguish of the Unknown springing up again; but it is also only a natural and momentary reaction after so much labour, on finding that Science does not yet calm our thirst for justice, our desire for security, or our ancient idea of an eternal after-life of enjoyment. In order, however, that Catholicism might be born anew, as some seem to think it will be, the social soil would have to change, and it cannot change; it no longer possesses the sap needful for the renewal of a decaying formula which schools and laboratories destroy more and more each day. The ground is other than it once was, a different oak must spring from it. May Science therefore have her religion, for such a religion will soon be the only one possible for the coming democracies, for the nations, whose knowledge ever increases whilst their Catholic faith is already nought but dust.
