“It is true. I cannot wait. I need to know; I need to be happy at once, and to know everything at once, and to be perfectly and forever happy. Oh, that is what makes me suffer, not to be able to reach at a bound complete knowledge, not to be able to rest in perfect felicity, freed from scruples and doubts. Is it living to advance with tortoiselike pace in the darkness, not to be able to enjoy an hour’s tranquillity, without trembling at the thought of the coming anguish? No, no! All knowledge and all happiness in a single day? Science has promised them to us, and if she does not give them to us, then she fails in her engagements.” Then he, too, began to grow heated. “But what you are saying is folly, little girl. Science is not revelation. It marches at its human pace, its very effort is its glory. And then it is not true that science has promised happiness.” She interrupted him hastily. “How, not true! Open your books up there, then. You know that I have read them. Do they not overflow with promises? To read them one would think we were marching on to the conquest of earth and heaven. They demolish everything, and they swear to replace everything—and that by pure reason, with stability and wisdom. Doubtless I am like the children. When I am promised anything I wish that it shall be given me at once. My imagination sets to work, and the object must be very beautiful to satisfy me. But it would have been easy not to have promised anything. And above all, at this hour, in view of my eager and painful longing, it would be very ill done to tell me that nothing has been promised me.” He made a gesture, a simple gesture of protestation and impatience, in the serene and silent night. “In any case,” she continued, “science has swept away all our past beliefs. The earth is bare, the heavens are empty, and what do you wish that I should become, even if you acquit science of having inspired the hopes I have conceived? For I cannot live without belief and without happiness. On what solid ground shall I build my house when science shall have demolished the old world, and while she is waiting to construct the new? All the ancient city has fallen to pieces in this catastrophe of examination and analysis; and all that remains of it is a mad population vainly seeking a shelter among its ruins, while anxiously looking for a solid and permanent refuge where they may begin life anew. You must not be surprised, then, at our discouragement and our impatience. We can wait no longer. Since tardy science has failed in her promises, we prefer to fall back on the old beliefs, which for centuries have sufficed for the happiness of the world.”
