Ongoing Tractatus Logico-Philosophicus reading group. And finally,
From all of the above, it seems that in the realm of logic, there is an unrestricted freedom of movement, or at least much greater than in any other space. This freedom is constrained and restrained, like (in) a funnel, the opposite of the Big Bang, as we move "down" to the other two spaces, while the mouth and end of the funnel can be considered as physical reality. Because many of the things that logic encompasses, ie whatever we can think of, do not exist in the natural world, just as many of the things described by geometry about the nature of space do not. However, logic, much like geometry, can examine everything, all possible states of affairs, without commitments and limitations, as long as it is bound only by itself, which doesn't tell us much, or rather, absolutely nothing.
And so, if anything conceivable is logical, anything we can think of, then the illogical has no place in our world; since we cannot think of anything illogical, but if we can conceive it, it automatically becomes logical. With such a broad definition of logic, no person is illogical, ever. But then, what about all those people that are confined, or not, to institutions, that seem to have lost their minds? Are they illogical? By our previous analysis, certainly not.
If we were to make an assumption in accordance with the above, we would say that their problem is not the lack or absence of logical thinking, but rather an abundance, or rather an overabundance of it: they are overly logical. Similar problems are faced by individuals with autism. Just as an autistic person absorbs a huge volume of information from the natural environment without being able to process it adequately to be what we call functional, similarly, someone labeled as "crazy" absorbs a massive amount of information from the realm of logic but cannot correlate that information received there to things and situations seen and felt in the realm of nature. Thus, they are not functional either, but rather constantly confused. Essentially, the confusion arises from the movement of thought as it moves between logical-geometric-physical space. But not only confusion, but all other feelings and emotions, such as fear and security, joy and sorrow, hate and love, interest and indifference, etc., can be explained in the same way. For example, when faced with the unlimited choices and possibilities as mentioned in the case of someone considered "crazy," they may feel fear at the prospect of this boundless freedom, a fear at some existential level, from which other things arise, such as a kind of mania. Therefore, we could say that they are not ultimately becoming illogical, but rather they are thoroughly logical, although I do not know how much this would help them. Laughter might also arise from the mixture of different logical forms among themselves or with natural forms, the result of which appears funny as they blend together. Art and music effectively does the same for us sane people, however under (some) control, because they both have the ability to move our thoughts to anything that can be conceived, along old or new paths, offering e-motions, thereby expanding our world.
Now, the mechanism or mechanisms behind all this, do not fall under, and are neither the scope of the science of logic, to find and expose them, but rather of other sciences. For instance, psychology will talk about how what is called the human psyche is influenced when thought moves from one object to another, what happens within us, what is the psychological relationship between what we say, what we think, and what we mean, why and how various psychological compulsions are created, etc. Or a biologist/pharmacist will search to find the materialistic mechanism/organ in the human body that makes people think, sometimes more or less logically, constructing substances and drugs to address problems. Such inquiries do not concern the logician, at least not in its pure form. For this reason, Wittgenstein, in the Tractatus, did not delve into psychology, biology, or the theory of evolution because he wanted to insist and remain in a purely logical analysis of phenomena, considering it rather the most important, and that anything else follows this or can be reduced to it, as if it doesn't make much sense to explore secondary issues. In his later work, Philosophical Investigations, however, he leads the reader to the same or different ideas through a psychological experiment conducted there. The therapeutic character, both of his early and later work, has been highlighted many times, by many thinkers, because, as they say, many of the problems that humans have, are ultimately dissolved, with his method, into being pseudo-problems. Through philosophy and the critique of language, as he uses them, functioning as therapy, a kind of speech therapy.
