There is talk of duality when is the fact meeting of two different characters or characteristics in the same person or thing.
Meeting of different characteristics in the same person or thing
Duality in this sense is seen as a particularity that things or people can present since it is unique that someone or something presents two different and opposite aspects or characteristics.
Let us think of a person who proves to be kind, proactive and always willing to solve the problems that arise from the future of his work on a professional level, while that same person, on a personal level, is very opposed to the one who is in the future. work: she is sullen, not very sociable, she does not want her close environment to bring her problems and she is not active when it comes to solving her personal problems.
Theology and Philosophy: Two Autonomous and Opposing Supreme Principles
Meanwhile, in the Philosophy and Theology is named dualism To that doctrine that precisely postulates the existence of two independent supreme principles, antagonistic and also irreducible.
For example, the notions of good and bad They turn out to be a good example of duality, because both are defined by opposition to each other and also suppose two totally opposite essences; matter-spirit and realism-idealism are some other expressions of dualism.
In the chinese philosophy the question of duality is an issue that is very present and forms the central part of the questions that it proposes. Through the notion popularly known as the yin and yang Chinese philosophy summarizes the dualities that are present in the universe.
The notion of yin and yang can be applied to any situation as well as to any object and mainly what it holds is that in everything good there will always be something bad and in everything bad it will be possible for us to find something good.
In philosophy, one of its greatest exponents, such as the Greek philosopher Plato, presented the issue of dualism in a forceful and clear way, so there we have a notion of the time that this concept has been addressed in both philosophy and theology.
For Plato there are two realities: one sensitive and characterized by imperfections, and on the other hand the reality of a perfect world, which is that of ideas.
Another distinction that he makes in relation to these two dissimilar realities is the body, which is part of the sensible and imperfect world, and of the soul, which on the contrary is eternal and perfect and is part of the world of ideas.
Plato argued that when the individual is born, the soul is enclosed in an imperfect body that at some point will find finiteness with death, while that very moment will be the liberation of the soul.
When later Aristotle appears on the scene, he will take care to deny this proposal, because for him the body and the soul were an indissoluble unit that is necessary.
In more modern times Plato's proposal is taken up, for example philosophers like Descartes and Kant will talk about the difference between matter and spirit.
For his part, theological dualism holds the existence of a divine principle: the good, which is associated with light and in absolute opposition to it is found another divine principle: evil or darkness. God is responsible for the creation of good while evil is attributed to the devil's ingenuity. The synthesis that theological dualism makes is that it removes man from all guilt and charge of the existence of evil in the world, that is, it frees him from the responsibility of causing it.
This current turns out to be flatly rejected by the Catholic Church , since it speaks of an omnipotent and infinite God who does not give rise to the existence of evil, which in some way limits his creative potential. Everything that exists on the planet was created by God, says the Catholic Church and therefore none of it can be bad.
Existence of two things at the same time
On the other hand, duality is the quality of existence of two things at the same time. "During a period in the club there was duality of presidents."
This situation can occur because, for example, there is an elected authority, such is the case of the example we gave, a president of a football club, and when the elections are held, another president is elected, however, a problem arises with the legitimacy of the same and then the two end up living together until the problem is solved.
It is not common but it is something that usually happens in politics especially.
