The first thing we are going to do is determine the etymological origin of the term deontology. In this sense we have to establish that it emanates from the Greek, because it is the result of the sum of two components of that language:
• “Deontos”, which can be translated as “duty or obligation”.
• “Lodge”, which is synonymous with “study”.

Deontology it is a concept that is used to name a class of treaty or discipline which focuses on the analysis of homework and of the values governed by the moral .

It is said that the British philosopher Jeremy Bentham He was responsible for coining the notion. Deontology is part of what is known as ethics normative (the philosophy which indicates what should be considered as good and what should be described as bad). This means that each profession, trade or specific field can have its own deontology that indicates what is the duty of each person .

Typically, certain professions have a code of ethics , which is a kind of manual that compiles the moral obligations that those who exercise a job .

It is important to note that ethics analyzes the internal duties of the individual; that is, what you should do or avoid according to what your awareness . Values ​​shared and accepted by ethics are collected by deontological codes.

Within the field of medicine, there is what is known as the code of medical ethics, of which we can highlight the following hallmarks:
• It is also called Medical Deontology.
• It is made up of the set of rules or principles of an ethical nature that must govern at all times the actions of professionals who work as doctors.
• Specifically, it is based on a series of principles that are considered to be the pillars of ethics of any professional who practices medicine: justice, charity, non-maleficiency and autonomy.
• It establishes that non-compliance with the aforementioned regulations will result in a disciplinary offense on which the corresponding authority must make decisions.

This code is formed, in the first place, by the oath of Hippocrates and then completed by other norms and guidelines that deal with issues such as the following:
• The doctor's relationship with the patients.
• The professional secret.
• Quality in regard to medical care.
• Conscientious objection.
• Human reproduction.
• Organ transplantation.
• Medical research.
• Medical care at the end of life.
• Relationships with other doctors, with other healthcare professionals or with the collegiate medical corporation.
• Medical teaching.
• Genetic tests.

The professional deontology applies to journalism , among other fields. Journalists, according to deontology, should always be handled with proven data, confirm the veracity of what they report, protect the sources that provide them with data and not cite content without mentioning the names of their authors, among other principles. If a journalist violates these criteria, he may receive different punishments according to the internal norms of the media in which he works.

Within this professional field, it becomes especially difficult to distinguish and respect two types of freedom closely related to journalism: that of expression and of information. The reason for their resemblance is that both pursue the goal of communicating something, although the main difference is in that something.

Few rights surpass that of expressing oneself freely, given that it is the basis of the struggle to be respected and the dissemination of the rest of the rights of human beings. In a nutshell, freedom of expression is related to opinionable subjects; that of information, on the other hand, revolves around events that are worthy of being published as news. Both freedoms are necessary to form a opinion spontaneous public, without oppression or invisible limits, but deontology makes its implementation not as simple as in a utopian world.

The freedom of information It implies the right that all human beings have to disseminate any history that reaches our ears, but deontology requires certain precautions in the process, some of which are mentioned in a previous paragraph, and the complexity of life does not it is always convenient or productive to make use of this freedom; there may even be cases in which preventing a third party from enjoying it is considered the most fair.

Returning to the concept of freedom of expression, which gives us the right to express our opinions, let's look at the two qualitative levels that can be distinguished:

* the inform function about a real event, that communicates a true and interesting message to the rest of the people. It is necessary to emphasize the importance in the veracity of the message, since it is the property that can invalidate its informative nature;

* opinion function, which is as important as the previous one, since both complement and enrich each other, and opinion is a natural and necessary consequence of the information.

Regarding opinion, it is not necessary to have the fundamental task of feeding and keeping democracy alive and collaborating with the fulfillment of human rights.
