What is Doctrine:
Doctrine is the set of principles, teachings or instructions that are considered valid and that belong to a school that can be literary, philosophical, political, military or the dogma of a religion.
Doctrine is related to discipline and everything that is the object of teaching that can be propagated in different ways, such as through education, preaching, the opinion of recognized or authoritative people, literature, and even through religions.
Likewise, the doctrine is based on the possibility of having universal validity, however, this is almost impossible due to the cultural and religious differences that exist in the great diversity of social groups that make up humanity.
On the other hand, the term doctrine is related to the concept of indoctrination, the latter has acquired pejorative connotations for referring to the teaching of beliefs that are considered true without being previously analyzed or discussed by those who learn them.
Hence, indoctrination is the re-education process imposed, for example, in countries with totalitarian regimes or in some religious studies.
The term doctrine derives from the Latin doctrine.
