That evening, after dinner, he told his wife, A strange case turned up at the surgery today, it might be a variant of psychic blindness or amaurosis, but there appears to be no evidence of any such symptoms ever having been established, What are these illnesses, amaurosis and that other thing, his wife asked him. The doctor gave an explanation within the grasp of a layman and capable of satisfying her curiosity, then he went to the bookcase where he kept his medical books, some dating back to his university years, others more recent and some just published which he still had not had time to study. He checked the indexes and methodically began reading everything he could find about agnosia and amaurosis, with the uncomfortable impression of being an intruder in a field beyond his competence, the mysterious terrain of neurosurgery, about which he only had the vaguest notion. Late that night, he laid aside the books he had been studying, rubbed his weary eyes and leaned back in his chair. At that moment the alternative presented itself as clear as could be. If it were a case of agnosia, the patient would now be seeing what he had always seen, that is to say, there would have been no diminution of his visual powers, his brain would simply have been incapable of recognising a chair wherever there happened to be a chair, in other words, he would continue to react correctly to the luminous stimuli leading to the optic nerve, but, to use simple terms within the grasp of the layman, he would have lost the capacity to know what he knew and, moreover, to express it. As for amaurosis, here there was no doubt. For this to be effectively the case, the patient would have to see everything black, if you'll excuse the use of the verb to see, when this was a case of total darkness. The blind man had categorically stated that he could see, if you'll excuse that verb again, a thick, uniform white colour as if he had plunged with open eyes into a milky sea. A white amaurosis, apart from being etymologically a contradiction, would also be a neurological impossibility, since the brain, which would be unable to perceive the images, forms and colours of reality, would likewise be incapable, in a manner of speaking, of being covered in white, a continuous white, like a white painting without tonalities, the colours, forms and images that reality itself might present to someone with normal vision, however difficult it may be to speak, with any accuracy, of normal vision. With the clear conscience of having fetched up in a dead end, the doctor shook his head despondently and looked around him. His wife had already gone off to bed, he vaguely remembered her coming up to him for a moment and kissing him on the head, I'm off to bed, she must have told him, the flat was now silent, books scattered on the table, What's this, he thought to himself, and suddenly he felt afraid, as if he himself were about to turn blind any minute now and he already knew it. He held his breath and waited. Nothing happened. It happened a minute later as he was gathering up the books to return them to the bookshelf. First he perceived that he could no longer see his hands, then he knew he was blind.

The ailment of the girl with dark glasses was not serious, she was suffering from a mild form of conjunctivitis which the drops prescribed by the doctor would clear up in no time, You know what to do, for the next few days you should remove your glasses only when you sleep, he had told her. He had been cracking the same joke for years, we might even assume that it had been handed down from one generation of ophthalmologists to another, but it never failed, the doctor was smiling as he spoke, the patient smiled as she listened, and on this occasion it was worthwhile, because the girl had nice teeth and knew how to show them. Out of natural misanthropy or because of too many disappointments in life, any ordinary sceptic, familiar with the details of this woman's life, would insinuate that the prettiness of her smile was no more than a trick of the trade, a wicked and gratuitous assertion, because she had the same smile even as a toddler, a word no longer much in use, when her future was a closed book and the curiosity of opening it had not yet been born. To put it simply, this woman could be classed as a prostitute, but the complexity in the web of social relationships, whether by day or night, vertical or horizontal, of the period here described cautions us to avoid a tendency to make hasty and definitive judgments, a mania which, owing to our exaggerated self-confidence, we shall perhaps never be rid of. Although it may be evident just how much cloud there is in Juno, it is not entirely licit, to insist on confusing with a Greek goddess what is no more than an ordinary concentration of drops of water hovering in the atmosphere. Without any doubt, this woman goes to bed with men in exchange for money, a fact that might allow us to classify her without further consideration as a prostitute, but, since it is also true that she goes with a man only when she feels like it and with whom she wants to, we cannot dismiss the possibility that such a factual difference, must as a precaution determine her exclusion from the club as a whole. She has, like ordinary people, a profession, and, also like ordinary people, she takes advantage of any free time to indulge her body and satisfy needs, both individual and general. Were we not trying to reduce her to some primary definition, we should finally say of her, in the broad sense, that she lives as she pleases and moreover gets all the pleasure she can from life.

It was already dark when she left the surgery. She did not remove her glasses, the street lighting disturbed her, especially the illuminated ads. She went into a chemist to buy the drops the doctor had prescribed, decided to pay no attention when the man who served her commented how unfair it was that certain eyes should be covered by dark glasses, an observation that besides being impertinent in itself, and coming from a pharmacist's assistant if you please, went against her belief that dark glasses gave her an air of alluring mystery, capable of arousing the interest of men who were passing, to which she might reciprocate, were it not for the fact that today she had someone waiting for her, an encounter she had every reason to expect would lead to something good, as much in terms of material as in terms of other satisfactions. The man she was about to meet was an old acquaintance, he did not mind when she warned him she could not remove her glasses, an order, moreover, the doctor had not as yet given, and the man even found it amusing, something different. On leaving the pharmacy the girl hailed a taxi, gave the name of a hotel. Reclining on the seat, she was already savouring, if the term is appropriate, the various and multiple sensations of sensuous pleasure, from that first, knowing contact of lips, from that first intimate caress, to the successive explosions of an orgasm that would leave her exhausted and happy, as if she were about to be crucified, heaven protect us, in a dazzling and vertiginous firework. So we have every reason to conclude that the girl with dark glasses, if her partner has known how to fulfill his obligation, in terms of perfect timing and technique, always pays in advance and twice as much as she later charges. Lost in these thoughts, no doubt because she had just paid for a consultation, she asked herself whether it would not be a good idea to raise, starting from today, what, with cheerful euphemism, she was wont to describe as her just level of compensation.

She ordered the taxi-driver to stop one block before her destination, mingled with the people who were following in the same direction, as if allowing herself to be carried along by them, anonymous and without any outward sign of guilt or shame. She entered the hotel with a natural air, crossed the vestibule in the direction of the bar. She had arrived a few minutes early, therefore she had to wait, the hour of their meeting had been arranged with precision. She asked for a soft drink, which she drank at her leisure, without looking at anyone for she did not wish to be mistaken for a common whore in pursuit of men. A little later, like a tourist going up to her room to rest after having spent the afternoon in the museums, she headed for the elevator. Virtue, should there be anyone who still ignores the fact, always finds pitfalls on the extremely difficult path of perfection, but sin and vice are so favoured by fortune that no sooner did she get there than the elevator door opened. Two guests got out, an elderly couple, she stepped inside, pressed the button for the third floor, three hundred and twelve was the number awaiting her, it is here, she discreetly knocked on the door, ten minutes later she was naked, fifteen minutes later she was moaning, eighteen minutes later she was whispering words of love that she no longer needed to feign, after twenty minutes she began to lose her head, after twenty-one minutes she felt that her body was being lacerated with pleasure, after twentytwo minutes she called out, Now, now, and when she regained consciousness she said, exhausted and happy, I can still see everything white.
