Philosophical realism, it is the basic aspect that defines that things exist independently of the human mentality.
One of the basic concepts for accepting that things exist independently of the human mentality, this is in the case of unexpected occurrences for each individual.
A catastrophe, a surprise, or any unexpected occurrence, is an event not envisioned by the human mind. Such would define evidence that things exist independently of the human mentality.
Others manage that the human mindset creates such unexpected occurrences. Suppose for example that a scientist analyzes a complex experiment that requires an enormous amount of calculations, these calculations are produced by a large computer and the answer is arrived at.
Then the same scientist manages to do the calculations using merely his mind and not the computer, and arrives at the answer. In this case, if his mind created the system, then he has a mind that can generate infinite calculations, and another extremely slowly.
Which would generate the concept of an infinite mind over a finite mind.
Would this idea be plausible? Neither plausible nor likely. It would not be reasonable, because a mind that had such a form of infinite processing, would generate on the test mind a variation as fast, as fast as the controlling mind.
In other words, one mind over another, it would be the same mind, so the processing speed would be the same. Thus, there would be no concept of time, in relation to the use of a supercomputer, or the use of paper and pencils.
Nor would it be probable because the same mind would be one in itself, and its infinite existence, and its finite existence, would lose the sense of existing. For the infinite would know that it is alone, and the finite would be merely a lie to the infinite. An infinite mind generated the function of generating lies, would nullify the sense of the infinite, and since they are merely one mind, they would cancel each other out.
In fact, every search to generate that the universe is dependent on the imagination of man, leads to dead ends, when we analyze the principles of the unexpected.
We can say that the Theory of the Unexpected, is everything that the human mind does not expect to happen, nor is it programmed to expect.
A random factor to the human concept, which mentally is not supposed to happen, but it does happen. An amazing discovery, detectable, but not imagined.
To build truths dependent on the human mind, in facts or situations unexpected to that same mind, is to seek a controller, and generator of the unexpected.
If we start to create a lot about this idea of a controller and generator of the unexpected, we will easily arrive at a controller, omnipotent, omniscient, and omnipresent.
Which again would fall into neither plausible nor probable situations.
Thus, the acceptance of realism as a factor of absolute truth, is the plausible and probable path. Concepts such as Physics, Chemistry, Medicine, Engineering, and others, are accepted and rationalized in realism.
Breaking such factors can generate a path to arrive at the principles of madness, by losing the rational system. The very concept that the relative truth is self-deniable, already shows the lack of logic.
The rational world in which we live determines that the only rationality is to define that the Absolute Truth exists, because if we say that the Absolute Truth does not exist, then this statement is the definition that the absolute Truth exists.
Defining that anything that is defined, is not linked to the idea of absolute truth, can only be when it is not affirmed, and that alone is an affirmation. So the denial of the statement itself is a statement.
In this case, there is only one directed path. Unless madness is sought, in this case rationality is disconnected, and the being becomes a disconnected randomness of no sense or order.
In that case the truth by Realism is certainly the truth by reason.
