Definition of fallacy
He is known as fallacy that reasoning a priori logical, in which its result is independent to the truth that is able to offer the premises that made us reach to the. For example, to better illustrate this you are saying, if we say, Martin is very good playing football, so Martin is very good, but of course, and how can easily detect, this conclusion is a fallacy, because we actually refer to the good behaviour of Martin but within a soccer field, then and outside this can be that Martin is a person evil and bad feelings. Actually this issue occurs in this case in particular ambiguity which holds good term, which makes that of course the premise is true but not its conclusion as well. While post so it seems an issue quite simple, understandable and easy to detect, in fact, in most of the time in our daily life don't we realize that much of the statements of politicians and some commercials are also invaded and structured their messages through fallacies, better, once again resort to the examples to clarify the question... When a politician says to another you do not have the moral to talk about this or that issue, go if we heard that statement at the time of the campaign, actually referring to that matter is attacking him personally more than anything its credibility, so that voters believe it and act accordingly, i.e., it does not attack him to the directly but making it through this issue which is a fallacy. On the other hand, the fallacy is a resource that is also widely used by advertising when selling products, for example, when you hire a celebrity or a person that particular issue proves to be a model or example for the common people to sell a product or service that has nothing to do with what makes for example, an actor promoting a perfume. Of course, the actor is not an expert in the field with which it is a fallacy that is purchased the perfume just because Antonio Banderas tells me, i.e., there are no prior recognition as an expert in perfumes that support its recommendations how certain. This type of fallacy it is called fallacy of authority.
