The concept of filiation is a complex concept that is used to refer to those parental relationships between two or more parties. Affiliation can be a biological or blood phenomenon, as well as a political, metaphorical or legal phenomenon. In any case, the idea of filiation always represents the relationship that exists between at least two different parties that are united through a bond of protection or care. Affiliation is an idea that the State also takes to refer to the links that it establishes with lower-ranking organizations and institutions. Thus, the dynamics of paternity is also reproduced at the legal, juridical or institutional level.
When we speak of filiation, we refer, basically, to the link that exists between two parties that are different from each other. This bond always has to suppose a certain protection and / or superiority of one of the two parties towards the other since if both parties were equal we would be referring to brotherhood or fraternity bonds. The most basic and representative relationship of the ties of filiation is the one that parents maintain with their children. This link is, in most cases, a biological, blood and genetic link, but depending on each case, it can also be legally established when, for example, a father legally adopts a child. Although there is no biological bond, there is a filial bond at the legal level.
The idea of affiliation is also present in other areas outside the family, for example when referring to the affiliate of a company or an institution. In this case, we will be talking about entities of lower rank than the main one that arise as a derivation of it and which the first must protect and encourage to continue operating.
