This was retranslated in August 19, 2007. But, I don't know English so well. So, please forgive it for the immature expression. Hiromasa Noguti.
	Kageura was talking with Sakazaki about the present strange phenomenon maybe psychic for long in the detached room. However, it isn't the problem so easy that it can solve it at once. "I think this isn't Cotosiro-nusi's handwork. I feel a more strong force than the vengeful god causing this.". Sakazaki, saying like that, gazed at Kageura as if it ask him to agree. Kageura says. "Sure, it doesn't look to be mere natural phenomenon. But, it is hard to assert it isn't related to the vengeful god in question.". As a matter of fact, recently, strange phenomenon often occurs anywhere in Japanese Islands. There often is a case the consistency at reality isn't kept for example between today and next day or between two o'clock and three o'clock. If it explains it with a exaggeration, for example a person working in Kyushu is, next moment, taking a lunch at a restaurant of somewhere in Osaka or getting on a train in Tokyo. To all appearances, it looked to be a phenomenon not concerning a logical consistence and causation. But, it never be that the said person moved from Kyushu to Osaka in an instant. And, he wasn't aware of the change of the situation like that at all. It seemed reality for him and his memory are changing at random, synchronized. Would it be the space-time was cracked in the reason of something and got invaded by the other space-time? Or else, should it say that countless space-time got mixed with each as if it is mosaic? However, the fact that people aren't aware of this strange phenomenon means a light and sound, and so on go through each wall of the mixed space-time. Isn't it strange? To all appearances, it doesn't seem this strange phenomenon occurs because of the mixed space-time. In other words, it seems it is mistake to think the space-time got mixed. It seemed there is a deeper cause behind this strange phenomenon. Is it the curse the vengeful gods and goddesses give off? Or else, would it be the sign showing the universe collapses? Anyhow, it was certain this is a serious problem for this world. However, at the moment, the people aren't aware of this strange phenomenon at all. Needless to say, it is because when reality for someone changes, his memory also reflects reality like that. Or else, would it be better to say reality for him reflects his memory? At any rate, it was impossible the people notice this strange phenomenon in principle. For example, when someone jumps from reality he is driving the car in Tokyo to the reality he is having a lunch in Kyushu, his memory also shifts to the memory he stored up until the present time he is taking a lunch since he was born. In other words, the memory about the former reality disappears completely. Therefore, since the consistency of his memory always is kept, it was impossible he falls into a confusion. At the moment, the actual strange phenomenon, for example, is in the situation that a substance looks to shift oneself to other position in no time within 1 micron in diameter in maximum. However, its effect never be so weak that it can be ignored for the people's consistence of the recognition. Especially, such phenomenon concerning memory and record had given the people the remarkable effect. It is because the contents of a letter, and so on change before a person notices, though it is a slight change. Anyhow, it was certain the strange phenomenon is expanding in this world rapidly. Needless to say, at the moment, the people are keeping the consistency of the recognition. However, it can't assert anymore they always have the memory of the same world. In that reason, it couldn't assert that the persons having the different memory from each don't meet in each other somewhere if they are under the unusual situation like that for long. In fact, people often were under the situation like that before noticing. And, the many of them had been caught to the strange sense unclear of the reason. However, at the moment, people are thinking the strange change of contents of a record, and so on occurred because of the error of writing or the lapse of memory. It was because not only the original paper but also the copies and memory change, synchronized. Strangely this phenomenon looked to occur without breaking the consistency of recognition. To all appearances, it doesn't seem it is mere physical phenomenon. It seemed someone's intention is concerning it. So, the people now are being caught to unidentifiable uneasiness. And, it also started to show the tendency to doubt the other persons.
			Certainly, at the moment, the people are living in almost same reality. However, if this phenomenon comes to be more conspicuous, the consistency between reality and memory may be torn completely. Isn't it that the space-time itself got schizophrenia? It was the situation so horrible that it makes a person think like that. Anyhow, it was certain the people will be confused, witnessing the phenomenon unable to understand. For example, the chief in the certain section of certain company may see his subordinate having died because of an accident last night is working as usual. It wouldn't be so hard to imagine the chief gets astonished terribly. If he is faint-hearted, it couldn't assert he doesn't faint. However, that his subordinate has died is the chief's reality persistently. The subordinate in question wasn't involved to the accident last night at one's reality. Or, it also can suppose the situation a stranger starts to do the work, sitting to the usual subordinate's seat in front of the chief suddenly. Of course, since the said stranger is the member of this section for long at his world, it is natural that he behaves like that. But, for the chief, it was a stranger persistently. It was certain the chief turns him out, using the guards or other.
	If it can't settle this confusion, no one can assert Japanese society doesn't collapse. It needed to inform the people about this problem as soon as possible. However, would it be really possible to inform the people about such strange phenomenon? By any chance, when the people notice this problem, this confusion already may be in the condition hard to settle. "If so, do we have to settle this confusion by only us?". Kageura was caught to the lonely mood like that suddenly. Furthermore, there is the serious problem deriving from this confusion. At the moment, this strange phenomenon occurs only in Japanese Islands. The foreign countries all are in normal reality. If so, it seems they notice at once the phenomenon without the consistency occurring in Japan. However, at that time, how would they cope to Japan? Would they try to rescue Japan really? By any chance, they may try to erase Japan to stop the strange phenomenon's spreading to the world. Anyhow, it was certain Japan is in the unprecedented crisis situation. Kageura says. "By any chance, this may be related to possibility world. Various possibilities supposed to be selected as one reality all have materialized as each realities. For the moment, I imagined like that.". But, Sakazaki, putting one's head on one side, glances up at Kageura. "Let me see, what does the possibility world mean?". He asked like that with the questioning look. Kageura says. "Well, for example, it assumes I now ate a chazuke(rice and tea) since I am busy. And, it assumes this is reality.". "Why, do you eat a chazuke in such a case?". "Oh, if so, is it better to say it eats a bread and butter? By any chance, I may go to a restaurant if I have enough spare time.". "Sure, there are many courses able to select, corresponding to the situation.". "Yes, one of those possibilities is selected as reality if it is the normal world.". "In this case, the possibility you eat a chazuke was selected as reality. May I understand like that?". "Yes, the possibility world is the world composed of the possibility like that. Therefore, in this case, it can assume there are the world of possibility I eat a bread and butter and the world of the possibility I eat a beef steak, or other.". However, Sakazaki felt Kageura's opinion strange a little. The possibility world is the world able to materialize persistently. It never be it exists as reality. "Isn't it that the possibility world is mere imaginary world? It is hard to think it influences this world.". Sakazaki asked Kageura like that with the dubious looks. Of course, Kageura had assumed the counterargument like that. It is because the possibility world isn't reality obviously. However, it can't assert that the possibility world isn't the real existence. It is because it thinks it is the mistake to think only this world is real existence. It is said the concept of the possibility world was born of a kind of the logic system of set theory called modal logic. And, it heard the modal logic treats the logical behavior of the concept of "inevitable" and the concept of "possible", or other though it is hard to understand the contents. It is certain the "possibility world" was found as the means for the logistic consideration, in the beginning. However, today, there are the scholars thinking the possibility world may be the real existence. For the moment, Kageuta explained like that about the possibility world.
	"Is it true? But, it like, is the parallel worlds the physics states. By any chance, is the possibility world the parallel worlds?". Sakazaki asked him like that out of mere curiosity. But, Kageura has the negative opinion about the parallel world because it seems it is confusing the possibility with reality. Kageura has pointed out only the problem like that simply. But, Sakazaki doesn't look to have understood Kageura's explanation. He started to speak his idea about the possibility suddenly. "But, I think reality is decided inevitably, because I think reality is the chain of the cause and result. Then, our decision what to do always is decided by the cause of something, too. In other words, reality is brought by the causation inevitably. Therefore, I can't accept the concept of possibility.". It doesn't know whether he said like that with the true intent. But, there is some truth in what he says. Kageura sank oneself into the thought for a little while. However, it seems it is hard to find the meaning of living if reality only is a set of inevitable result. Kageura, while listening to Sakazaki, was waiting the opportunity to refute.
	Sakazaki says. "It is impossible to grasp for why was the certain decision brought, and what result it brings. Needless to say, it is because we aren't the Almighty. Therefore, we complement our incomplete conjecture, using the concept of possibility for convenience. I can't think there is the possibility world.". Kageura felt it to be the mechanical fatalism. Sakazaki, often investing in the stock, is getting the capital gain. And, he once said I have never done the failure. In other words, he, guessing the inevitable trend of the stock prices, is investing in the stock. It seemed it is natural that he attaches importance to inevitability. Kageura says. "Oh, is that right? If so, do you say the situation we argue this problem here had been decided when this universe was born ?". "Yes, it is! I think it is possible to know what occur next moment if it grasps all conditions including our internal condition.". "Why, it is impossible to know all conditions!". "Sure, in that reason, we need the concept of possibility as the tool to complement our imperfect recognition.". "Hum, do you say possibility is phantom?". Kageura asked him like that with the ironical tone in spite of oneself. Next moment, Skazaki asserts "Yes it is" with the clear tone at once. Kageura sank oneself into the thought for a little while. It is because it was dissatisfied with his attitude giving the clear conclusion easily than with his opinion itself. Thereupon, Kageura started to speak from the other viewpoint. "When it makes behavior of something in the completely same method under the completely same conditions, it is supposed the result brought by the behavior like that always is the same. But, if it assumes something randomly comes into this world from the different world, it has to think the different result from the given result like that is brought." "Why, what do you mean by different world?". "Well, it may be better to say it is the world we can't perceive in principle.". Kageura, when answering like that simply, started to speak one's idea again. In physics, it is said a pair of a electron and a positron often appears to the empty space randomly. However, it hears since they appear in the very close space in each other, they disappear at once, reacting because of each force. Kageura imagined a pair like that appears because of the temporary condition this world borrows the different world's energy. However, energy is energy persistently even if it is different world's energy. If so, it seems it is possible the particles in this physical world collide with a particle suddenly appearing like that(electron or positron). However, would it be possible to guess when the collision like that occurs where? It seems it can't but think they happened to collide accidentally. If so, it can't assert it is inevitability. "Therefore, I think the concept of possibility is reflecting the actual situation of this world certainly. How do you think about it?". Kageura asked like that, glancing up at Sakazaki. However, Sakazaki says "But, it is possible to imagine a pair like that to appear under the certain probability of occurance.". "What?". Kageura got bewildered because of Sakazaki's unexpected utterance slightly. It is because Sakazaki put the concept of probability in the major premise of the argument. But, the major premise for the concept of probability is the concept of possibility. Kageura put one's head on one side in spite of oneself. To all appearances, Sakazaki looks to be not aware of the thing at all. Sakazaki kept on stating one's opinion with the complete self-confidence.
			According to Sakazaki, the orbits of the particles in this world had been decided by the causation and the logical relationship of all phenomenon inevitably. If so, it is possible to guess the phenomenon some particle like that causes, colliding with the particle coming from the different world(electron or positron) under the certain mathematical probability. And, if so, it is possible it think it is inevitable phenomenon to occur under the certain mathematical probability. Or, a pair of a electron and positron may appear, dodging the collision like that because it seems the collision like that breaks the causation and logical relationship at least at this world. "By any chance, it may be better to think the pair like that also appear inevitably". Sakazaki, saying like that, stuck out one's chest. To all appearances, the major premise for argument he stated is strange. "Wait a minute!". Kageura, saying like that with the impatient looks, interrupted him. As it thought, first of all, it seems to need the recognition common to the argument, confirming the concepts about "inevitability", "possibility", and the concept of "mathematical probability", and so on. Kageura, when pointing out the thing to him, started to speak one's recognition about those concepts.
	According to Kageura, the character to lead to the only conclusion under the certain conditions is conceptualized like "inevitability". And, the character to lead to several conclusions under the certain conditions is conceptualized like "possibility". Therefore, the mathematical probability is the percentage of the certain possibility's materializing. And, when it assumes that the mathematical probability of when certain phenomenon occurs under certain conditions is a hundred percent, it can say it occurs inevitably. "In other words, the "inevitability" is the special state of the possibility. How do you think about it?". Kageura, when finishing stating one's recognition about the concepts in question simply, asked Sakazaki like that. Sakazaki also answers "I think so" simply. Thereupon, Kageura again started to speak one's idea. "In other words, the inevitability is a kind of the possibility. If so, reality may be one of countless possibility worlds.". Sakazaki says. "But, the "inevitability" isn't the concept expressing reality. It only means that it necessarily materializes as reality. Therefore, this world, that is, reality isn't possibility world.". To all appearances, it is the understandable opinion. Kageura withdrew at once what it said.
	However, the "inevitability" is only one state of many possibilities. And, not until the probability the certain possibility materialize is a hundred percent, the concept of "inevitability" is used. If so, isn't it unsuitable to use this concept until the certain possibility appears as reality? Isn't it that the concept of inevitability only is used for the convenience, to accept reality? Isn't it that the concept of inevitability only expresses the fact one of the countless possibilities materialized as reality? At that time, Kageura was feeling the impression like that from the concept of inevitability. However, he still has the problem to show. If it doesn't distinguish the problem of whole and the individual problem, it is hard to find out a right answer. Kageura stumbled on the certain assumption for the thing suddenly, and started to speak about the assumption. However, it may not have needed to speak about this assumption because it is too ordinary talk. But, since it had started to speak, it can't be helped anymore. He was obliged to explain one's idea by that assumption almost in natural course.
	In his assumption, the certain pharmaceutical company found out the ingredient supposed to be effective for making a person slim. Thereupon, the research workers examined the effectiveness, preparing the rats of numbers necessary for the experiment. And, it could confirm it is effective for the eighty percent of the rats. In other words, it was effective for the eighty percent of the rats inevitably. However, it couldn't know why it isn't effective for the remaining twenty percent of the rats. Therefore, it can't confirm whether it is effective or not for a individual rat if it doesn't give the said rat the ingredient in question. If so, even if it is effective for the eighty percent of the rats inevitably, it can't get the more detailed answer than the answer the probability it can be effective for individual rat is eighty percent. "Therefore, I think we have to pay attention to mistaking the problem of the whole for the individual problem.". Kageura, saying like that, gazed at Sakazaki as if it asked him to agree. Sakazaki says. "Sure, but, I think the probability like that comes from the lack of the necessary information. In other words, it can confirm whether it is effective or not inevitably for individual rat if it can know all conditions of weakening the effectiveness of the ingredient in question.". To all appearances, Sakazaki doesn't look to have understood Kageura's intention. "Oh, I stated the example to make clear the difference between the problem of whole and the individual problem persistently. As for whether a possibility is the mere process arriving at a inevitability, it is future problem. Before that, I have one problem to solve". Kageura, saying like that, started to speak one's idea again. Kageura had thought the concept of inevitability, possibility, and the concept of probability are used under the given conditions at the thinking. But, if it tries to guess certain phenomenon actually, it needs many data. In other words, the thinking under the certain conditions means the using the minimum data necessary to guess the phenomenon in question. But, in that, would it be possible to say it can guess the phenomenon completely? Even if the probability the certain possibility materializes is a hundred percent, it feels there are unknown uncertain conditions besides the calculated conditions like that always. Isn't it that it only can say the concept of inevitability is effective under the certain restricted conditions? Not until one conjecture became reality if it thinks exactly, isn't it that the concept of inevitability can be used? The concept of inevitability and the concept of possibility both often are used when it guesses the future. However, if the "inevitability" is used there, it drives away all the other possibilities. Isn't it that it is mistake? Isn't it that the other possibilities don't disappear until one possibility materializes as reality? It doesn't seem there can be a phenomenon occurring inevitably at least for human being, if it thinks exactly. As it stated before, it seems there are the unknown uncertain conditions. However, Sakazaki says reality all is being decided objectively and inevitably from the beginning. He says it only is that we can't know the thing. And, Sakazaki asserted that even the unknown uncertain conditions Kageura stated before are in the already inevitable condition though nobody can know the thing. "Why, is that right really?". Kageura, when putting the head on one side, saying like that, asked him, "If so, who can assert the unknown uncertain conditions, as a matter of fact, are the inevitable conditions?". Since, it is called uncertain conditions because nobody can know the thing, It was natural that Kageura asked like that. However, For Sakazai, it looks to be hard to understand the matter Kageura offered. For the moment, he answered "Let me see, it probably is everybody because it is being decided objectively.". To all appearances, it is the strange answer. Kageura says. "If so, what kind of thing is the objectivity you stated? In this case, the uncertain conditions, as a matter of fact had been decided objectively and inevitably, you said. If so, is it the objectivity the gods and goddesses perceive? Who the devil decides whether it is inevitable and objective or not? In this case, who the devil is the cognition-person?". However, Sakazaki puts the head on one side. "What do you mean?". Sakazaki asked him like that with the bewildered looks.
			Usually the words of the objective recognition are used when everybody have the same recognition under the certain verification about the certain things. And, the objective recognition like that is based on the proper recognition the individual persons have. However, Sakazaki isn't considering the thing at all. If it is possible the objectivity he stated be, it is certain the soul giving the objectivity isn't a human being. And, it also isn't the gods and goddesses probably. It was because it seems that the gods and goddesses aren't needed if all occurs inevitably. However, it seems it is hard to explain the thing well now. Before the argument, it seemed the more deep contemplation is needed.
