The knowledge in general can be understood from many points of view: through themes, items, or stories from a practical perspective or theoretical. When certain ideals in a given area form a homogeneous set , we are faced with a doctrine.
It is possible to speak of doctrine from a religious, cultural or political point of view. Usually, it is the religion that most applies this concept, as the various principles, dogmas and values of a religious belief can be grouped together and form a doctrinal body, that is, a series of norms, ideas and recommendations.
The main characteristic of any doctrine is the coherence between its various elements.
It would make no sense for a religious principle to contradict another, the same happens with the political area .
Another important aspect of the doctrine is its desire for dissemination and expansion. Religious or political ideals aim to gain adherents or followers, as they need to create doctrinal documents that serve to know the content of religious beliefs or their political ideals.
As a general rule, each doctrine opposes the other, in such a way that they establish a rivalry among themselves, like liberalism that opposes absolutism and materialist doctrines that confront spiritual ones.
When a doctrine loses its value for some reason, groups appear that propose a new doctrinal project
In the religious field this circumstance manifests itself through heresies (beliefs are deviated from one doctrine and create a different one).
In the case of the Catholic religion, its doctrine comes from several texts (mainly the Bible), but which are grouped in a single doctrinal document , in this case the catechism.
The term doctrine has, in principle, no negative connotations…
However, when a person or a group tries to convince the other of something an indoctrination happens, in this case there can be a pejorative sense in relation to the use of this word. Indoctrination is opposed to the idea of teaching. In fact, teaching means informing the other person about a topic objectively and with the purpose of finally proposing your own ideas. On the contrary, indoctrination recruits faithful followers who are submissive to a dogma and which, on occasion, allows us to discuss .
It is not easy to draw a boundary between teaching and indoctrination, as they are two ideals that have common connections. Anyway, whoever teaches something wants to convince the other and, at the same time, the one who indoctrinates also teaches the neighbor to think.
