The notion of objection consciousness is relatively new in the history of Man and has to do basically with the possibility of refusing to participate in any activity (especially public) if it is faced with the beliefs and convictions of the subject in question.
The relevance of this notion is that it has to do directly with recognizing the freedom of each person to determine their life without other forces invading and deciding for it.
The ability to refuse as a subjective right
We could locate the historical beginning of the figure of conscientious objection in the year 1789, the year in which the French Revolution happened and a great number of things would change since then and forever in the West. Thanks to the Declaration of Rights of Man and of the Citizen, this revolution proclaimed the freedom of the person as one of the most important assets that we possess. That freedom is understood as pre-existing and even goes so far as to allow the person to refuse certain obligations , such as being forced by convictions to join the army or to be intervened in the event that such medical intervention is contrary to the religion that one professes .
Objection by conscience means in other words that the person does not coincide with the ideals that drive certain events or situations. It is a right that is considered part of the private and very personal sphere, for which reason it pre-exists and prevails before any decision or power that the State, for example, or other forces wish to have over the individual.
A right that can sometimes become a problem for others
Conscientious objection is a vitally important right as it reminds us all that our minds, our convictions, and our ideals are above what others want to impose on us. But this can certainly become a problem if the person refuses to collaborate or be part of activities that he opposes and that are designed for others.
A clear example of when this figure can become problematic is when medical professionals refuse to carry out certain practices that help the person suffer less (such as euthanasia) or end the life of a fetus (in the case abortion). Here, this legal element allows individuals not to take part in these activities but may collide with the decisions of third parties.
