“A great mind—the greatest of the century!” exclaimed Casanova. “To give him such a designation seems to me inadmissible, were it only because, for all his genius, he is an ungodly man—nay positively an atheist. No atheist can be a man of great mind.”

“As I see the matter, there is no such incompatibility. But the first thing you have to prove is your title to describe Voltaire as an atheist.”

Casanova was now in his element. In the opening chapter of his polemic he had cited from Voltaire’s works, especially from the famous Pucelle, a number of passages that seemed peculiarly well-fitted to justify the charge of atheism. Thanks to his unfailing memory, he was able to repeat these citations verbatim, and to marshal his own counter-arguments. But in Marcolina he had to cope with an opponent who was little inferior to himself in extent of knowledge and mental acumen; and who, moreover, excelled him, not perhaps in fluency of speech, but at any rate in artistry of presentation and clarity of expression. The passages Casanova had selected as demonstrating Voltaire’s spirit of mockery, his scepticism, and his atheism, were adroitly interpreted by Marcolina as testifying to the Frenchman’s scientific genius, to his skill as an author, and to his indefatigable ardor in the search for truth. She boldly contended that doubt, mockery, nay unbelief itself, if associated with such a wealth of knowledge, such absolute honesty, and such high courage, must be more pleasing to God than the humility of the pious, which was apt to be a mask for lack of capacity to think logically, and often enough—there were plenty of examples—a mask for cowardice and hypocrisy.

Casanova listened with growing astonishment. He felt quite incompetent to convert Marcolina to his own way of thinking; all the more as he increasingly realized that her counterstrokes were threatening to demolish the tottering intellectual edifice which, of late years, he had been accustomed to mistake for faith. He took refuge in the trite assertion that such views as Marcolina’s were a menace, not only to the ecclesiastical ordering of society, but to the very foundations of social life. This enabled him to make a clever change of front, to pass into the field of politics, where he hoped that his wide experience and his knowledge of the world would render it possible for him to get the better of his adversary. But although she lacked acquaintance with the notable personalities of the age; although she was without inside knowledge of courtly and diplomatic intrigues; although, therefore, she had to renounce any attempt to answer Casanova in detail, even when she felt there was good reason to distrust the accuracy of his assertions—nevertheless, it was clear to him from the tenor of her remarks, that she had little respect for the princes of the earth or for the institutions of state; and she made no secret of her conviction that, alike in small things and in great, the world was not so much a world ruled by selfishness and lust for power, as a world in a condition of hopeless confusion. Rarely had Casanova encountered such freedom of thought in women; never had he met with anything of the kind in a girl who was certainly not yet twenty years old. It was painful to him to remember that in earlier and better days his own mind had with deliberate, self-complacent boldness moved along the paths whereon Marcolina was now advancing—although in her case there did not seem to exist any consciousness of exceptional courage. Fascinated by the uniqueness of her methods of thought and expression, he almost forgot that he was walking beside a young, beautiful, desirable woman, a forgetfulness all the more remarkable as the two were alone in the leafy alley, and at a considerable distance from the house.

Suddenly, breaking off in the middle of a sentence, Marcolina joyfully exclaimed, “Here comes my uncle!”

Casanova, as if he had to rectify an omission, whispered in her ear: “What a nuisance. I should have liked to go on talking to you for hours, Marcolina.” He was aware that his eyes were again lighting up with desire.

At this Marcolina, who in the spirited exchange of their recent conversation had almost abandoned her defensive attitude, displayed a renewed reserve. Her expression manifested the same protest, the same repulsion, which had wounded Casanova earlier in the day.

“Am I really so repulsive?” he anxiously asked himself. Then, replying in thought to his own question: “No, that is not the reason. Marcolina is not really a woman. She is a she-professor, a she-philosopher, one of the wonders of the world perhaps—but not a woman.”

Yet even as he mused, he knew he was merely attempting to deceive himself, console himself, save himself; and all his endeavors were vain.

Olivo, who had now come up, addressed Marcolina. “Have I not done well to invite some one here with whom you can converse as learnedly as with your professors at Bologna?”
