Reasonability is a very useful and important quality. There are not so many people distinguished by them in our time. Reason expresses the highest type of mental activity. Or, in other words, thanks to him, the individual is able to think, generalize, analyze, abstract, and so on. But this is only a brief description of the properties of the mind. In general, this topic needs to be considered in more detail.
About the concept
Reasonability is a person’s quality that allows him to correctly apply the knowledge gained in the process of life. In philosophy, there is an excellent synonym for this concept - expediency. This term determines how much one or another process / phenomenon corresponds to a state whose ideal model is represented as a goal. A person who is characterized by both qualities is guided exclusively by reason in his actions. He is not used to obeying desires and emotions or acting spontaneously.
Reasonable thinking is expressed through speech and through the commission of certain actions. Both one and the other are accompanied by analysis. This is a concept that is familiar to all. Analysis, in simple terms, involves a method of researching something by dividing an object into several parts. That is, its decomposition "on the shelves." Having considered each component individually, it turns out to draw the most correct conclusion. This manifests the human mind.
Good example
Our life is full of different situations. And rationality is a quality that, fortunately, is manifested by many every day. But as an example, it is worth giving an exaggerated situation. As mentioned above, the main property of the mind is its resistance to feelings and emotions. For example, there are two people. Two adult brothers who are for each other the closest and dearest people in the whole world.
At some point, one of them begins to suffer from a mental illness, because of which he poses a danger to society. The consequences are not long in coming. In a spontaneous fit of anger, he kills several people, after which he tells in a panic about what happened to his brother, begging him not to report to the relevant authorities. And he, pitying a relative, in every possible way covers him.
It is reasonable to act, of course, in a different way. It will be correct to report this to the police and psychiatric clinic so that the offender is isolated from society in order to avoid other victims. But in situations so difficult from the point of view of morality, emotions usually prevail, not rationality. It is a fact.
About the power of quality
Everything that we possess is developed to one degree or another. Reasonability is a quality whose strength depends on self-control. If it is not peculiar to a person, then it is difficult to call it expedient. After all, what is the mind? This is the ability of a person to properly perform his duties and duty. And feelings for this turn inward, but not outward. The human mind has its own characteristics. And the fact that this or that person possesses it does not at all exclude the presence of her desires. An intelligent person is not cold and insensitive, to whom joys are alien. He just knows how to keep everything under control.
For example, a person received a tempting offer from a tour operator about a last-minute ticket, which can be bought at a 90% discount. And he lights up with this idea! A person is ready to immediately drop everything and go to rest. But is it appropriate? Indeed, in the office there is a traditional “blockage”. Going on a trip, there is a risk of losing your job. And it is possible that even a ticket with such an impressive discount will then seem like an unattainable purchase for a long time to come. Therefore, it is better to analyze everything, pull yourself together and hold off.
Awareness
This quality should also be noted with attention, talking about what the mind is. It is very important. Because it is a fundamental feature of rationality. A reasonable person can know a lot. Everything that surrounds him, he understands perfectly. But the main thing is not that. And the fact that he realizes and puts into practice everything that he understands and knows. This is not characteristic of every person.
An oncologist can describe the consequences of smoking in colors, show terrifying presentations, show photos and even real lungs of people who use tobacco. But can it be called reasonable if, after completing the lecture, he goes outside and takes a drag on a cigarette? Knowledge and awareness are two different things. And certainly they are not synonyms.
Lack of bias
This is another quality that a reasonable person possesses. A creature is intelligent only if it is unbiased. It's hard to argue with that. What is bias? In simple words, this lack of impartiality, accompanied by a clear prejudice and an initial tendency to a particular position. In general, it is a quality that prevents being adequate and reasonable.
There are many examples in life. Suppose a person does not like people of one or another nationality. Once he is offered a walk in the company, he agrees. There he meets new good friends, and with one, communication begins to actively develop, growing into friendship. And then he becomes aware - this person is a representative of precisely that nationality, to which he feels fierce hostility. An adequate attitude to him disappears and everything good is canceled out only because of his ethnic identity. Is this person reasonable? Not. Is biased? Definitely.
Stereotypes
This is the last thing I would like to say a few words about. An intelligent person never follows stereotypes and cliches. The only thing he believes is his eyes and ears. Its difference from ordinary people is the lack of a framework. He is free in his opinion and outlook. It may seem that this topic is somewhat remote from rationality. But this is not so. After all, we are talking about philosophical concepts, and all of them, one way or another, are interconnected with each other.
